The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0060] Before the embodiments of the present application are described in detail, first, some nouns and terms involved in the embodiments of the present application are explained, and the nouns and terms involved in the embodiments of the present application are applicable to the following explanations.

[0061] 1) Service discovery server (SD server), refers to the process of automatically discovering available network services in a network. The service discovery server is a server responsible for managing and providing service discovery functions. The service discovery server usually stores information of available services in the network, such as the location of the service, IP address, port number, etc.

[0062] 2) ARXML Document (AUTOSAR XML) is an XML format used in the Automotive Open System Architecture (AUTOSAR) framework. ARXML is a data format used by AUTOSAR to describe and exchange information about software components and system configurations for automotive systems.

[0063] 3) Software Component Execution Unit (SWC Runnable) refers to a task unit that can be independently executed within an AUTOSAR Software Component (SWC). SWC is a basic building block in the AUTOSAR architecture, representing a software module with specific functionality. Each SWC can contain one or more runnables.

[0064] 4) Method Identifier (Method ID) is used in the AUTOSAR (Automotive Open System Architecture) framework to identify services within a SWC (Software Component).

[0065] 5) Group Identifier (GROUP ID) is used to group related SWCs together to form a logical software group. Software groups represent specific functions or subsystems in automotive systems, such as engine control units, chassis control units, etc.

[0066] 6) Automotive Open System Architecture (AUTOSAR) is an open, standardized automotive software architecture developed by the automotive industry and suppliers. It aims to provide a modular, scalable and reusable solution for automotive software development. The AUTOSAR architecture aims to support the complexity of automotive electronics and software systems while improving development efficiency, reducing costs, and ensuring system reliability and safety.

[0067] With the continuous development of the automotive industry, the integration and optimization of software and hardware become increasingly important. Automotive manufacturers and suppliers must ensure the high reliability, safety and performance of automotive software. To achieve these goals, AUTOSAR (Automotive Open System Architecture) and ARXML (AUTOSAR XML) files have become key tools. AUTOSAR provides a set of specifications for developing, testing and deploying automotive software, while ARXML files are used to describe and manage automotive software components and system configurations. However, traditional ARXML document parsing methods have some problems that limit their efficiency and effectiveness in practical applications.

[0068] Firstly, traditional ARXML document parsing methods are complex. Parsing ARXML files and extracting relevant information usually requires a lot of manual operations or a large amount of custom code. This method leads to a large amount of work and complexity, requiring professional knowledge and a deep understanding of the AUTOSAR architecture. In addition, since ARXML files contain rich configuration information and software architecture descriptions, manually identifying or parsing ARXML files is very time-consuming and prone to errors.

[0069] Secondly, the error rate is high. In the traditional document parsing process, due to human operation errors or understanding errors, configuration errors or inaccurate information extraction may occur. These errors may cause abnormal behavior of the automotive system, and even may cause safety problems.

[0070] In addition, the traditional document parsing method has poor fault tolerance. In actual application, various abnormal situations may be encountered, such as subscription request failure, communication interruption, etc. The traditional parsing method often lacks processing of these abnormal situations, and cannot capture error information or status codes in time. This may cause the system to be unable to respond to problems in time, affecting the performance and safety of the automobile.

[0071] Finally, the traditional document parsing method is not flexible and difficult to handle ARXML files of different structures and levels. With the increasing complexity of automotive software, the structure and level of ARXML files also become more and more complex. The traditional parsing method often lacks flexibility and scalability, and is difficult to meet the changing needs of automotive software.

[0072] In summary, although ARXML files play an important role in the integration and optimization of automotive software, traditional ARXML document parsing methods have some problems.

[0073] Therefore, the application provides a document parsing method and device, equipment and medium. The method comprises the following steps: reading the content of an ARXML document, parsing the read content into a tree structure of an XML document, simplifying the work flow, reducing the work difficulty and reducing the workload; obtaining a root node of the tree structure, taking the root node as a current node; extracting and parsing the information of the current node, ensuring the accuracy and completeness of the extracted data, helping to generate a correct service signal and reducing the error rate; if the current node has a child node, taking the child node as the current node and returning to the step of extracting and parsing the information of the current node, which is beneficial to flexibly processing ARXML files with different structures and levels and enhancing the flexibility and expansibility of the system; generating a service signal according to the extracted and parsed information and sending the service signal to a server as a subscription request; obtaining the processing result of the subscription request; if the processing result is a subscription failure, obtaining the error information or status code returned by the server, helping the terminal to respond to problems in time and take corresponding measures, and improving the fault tolerance, stability and reliability of the terminal.

[0074] The document parsing method provided in the application is related to the technical field of communication. The document parsing method provided in the application can be applied to a terminal, can also be applied to a server, and can be software running in the terminal or the server. In some embodiments, the terminal can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a vehicle-mounted terminal and the like, but is not limited thereto; the server can be configured as a stand-alone physical server, can also be configured as a server cluster or a distributed system composed of multiple physical servers, can also be configured as a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN and big data and artificial intelligence platform, and the server can also be a node server in a blockchain network; the software can be an application for implementing the document parsing method, but is not limited to the above forms. In addition, the terminal and the server can adopt a C / S architecture, the terminal is a client, and the server is a server. Those skilled in the art can understand that the client and the server can run on one device or at least two devices.

[0075] The application is operable in a variety of general purpose or special purpose computer systems environments. Examples of well-known computer systems, environments, or configurations that can be suitable for use with the application include, but are not limited to, personal computers, server computers, handheld or laptop devices, tablet devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like. The application can be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, and the like, that perform particular tasks or implement particular abstract data types. The application can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote computer storage media including memory storage devices.

[0076] FIG. 1 is an optional flowchart of a document parsing method according to an embodiment of the application. The method in FIG. 1 can include, but is not limited to, steps S101 to S107.

[0077] In step S101, the content of the ARXML document is read, and the read content is parsed into a tree structure of the XML document.

[0078] The application does not make specific limitations on the way of reading the content of the ARXML document, and can be flexibly selected according to actual parsing needs. For example, an XML parsing library can be used to complete the reading, or other tools can be used to complete the reading. In step S101 of some embodiments, the ElementTree library in Python can be used to read the content of the ARXML document. The content of the ARXML document can also be read through the BeautifulSoup library, without being limited thereto.

[0079] In this embodiment, the content of the ARXML document is read, and the read content is parsed into a tree structure of the XML document, so as to convert the content of the ARXML file into a tree structure which is easy to process and operate, thereby providing basic data for subsequent steps.

[0080] In step S102, the root node of the tree structure is obtained, and the root node is taken as a current node.

[0081] In some embodiments, the root node is obtained from the parsed tree structure, and is set as the current node, so as to extract and parse information from the root node.

[0082] In this embodiment, the root node of the tree structure is obtained, and the root node is taken as the current node, thereby ensuring that the information is processed from the top of the ARXML file, and providing a starting point for subsequent steps.

[0083] Step S103, information of the current node is extracted and parsed.

[0084] Specifically, the information of the current node includes a tag, an attribute, and text content. The attribute information of the current node includes a data type, a SWC runnable, a port, a type mapping, a signal node, a communication ID, a method identifier, and a group identifier.

[0085] In some embodiments, the information contained in the current node is extracted and parsed.

[0086] Optionally, the extraction and parsing can be, but are not limited to, extracting information such as a data type, a method identifier, a group identifier, and a period related to Ethernet communication.

[0087] It can be understood that the extracted information of the current node can be stored.

[0088] The storage structure of the information of the current node is not specifically limited in the present application, and can be flexibly selected in combination with actual parsing needs. Exemplarily, the information of the current node can be stored as a key-value pair, or as an object.

[0089] In the present embodiment, the information of the current node is extracted and parsed, which prepares for generating a service signal.

[0090] Step S104, if the current node has a child node, the child node is taken as the current node, and the step of extracting and parsing the information of the current node is returned.

[0091] In some embodiments, if the current node has a child node, the child node is taken as the current node, and the step of extracting and parsing the information of the current node is returned, until the current node has no child node.

[0092] In the present embodiment, if the current node has a child node, the child node is taken as the current node, and the step of extracting and parsing the information of the current node is returned, which ensures the step-by-step traversal of the entire ARXML document, thereby completely extracting all required information.

[0093] Step S105, a service signal is generated according to the extracted and parsed information, and the service signal is sent to the server as a subscription request.

[0094] Specifically, the service signal includes a data type, a method identifier, and a group identifier.

[0095] In some embodiments, the data type, the method identifier, and the group identifier are obtained from the node information, a service signal is generated, and the service signal is sent to the server as a subscription request.

[0096] The server is not specifically limited, and can be selected flexibly according to actual analysis needs. For example, an SD server or a cloud server can be used.

[0097] Optionally, the period, the data type, the method identifier, and the group identifier are obtained from the node information, a service signal is generated, and the service signal is sent to the server as a subscription request. The period is used to accurately specify a time interval of data transmission in the subscription request.

[0098] In this embodiment, the service signal is generated according to the extracted and parsed information, and the service signal is sent to the server as a subscription request, which can improve the timeliness and accuracy of data, and enables the server to register the service, so that the service can be discovered, subscribed, and used by other nodes in the network.

[0099] In step S106, a processing result of the subscription request is obtained.

[0100] Specifically, the processing result includes subscription failure or subscription success.

[0101] In some embodiments, the processing result of the subscription request can be obtained by waiting for a response of the server, or can be obtained by polling the processing result, and is not limited thereto.

[0102] In this embodiment, the processing result of the subscription request is obtained, which prepares for subsequent error processing.

[0103] In step S107, if the processing result is subscription failure, error information or a status code returned by the server is obtained.

[0104] In some embodiments, if the processing result of the subscription request is failure, the terminal obtains error information or a status code returned by the server, so as to perform error processing.

[0105] Optionally, the status code can be used to determine an error type, so as to determine an error processing manner, or can be used to determine an error position, so as to determine the error processing manner.

[0106] In this embodiment, if the processing result is subscription failure, error information or a status code returned by the server is obtained, which is helpful to identify and solve problems occurring in the subscription process in a timely manner, and improves stability and reliability.

[0107] The steps S101 to S107 shown in the embodiments of the present application simplify the workflow, reduce the work difficulty, and reduce the workload by reading the content of the ARXML document, parsing the read content into a tree structure of the XML document; obtaining a root node of the tree structure, taking the root node as a current node; extracting and parsing information of the current node to ensure the accuracy and completeness of the extracted data, which helps to generate a correct service signal and reduce the error rate; if the current node has a child node, taking the child node as the current node and returning to the step of extracting and parsing the information of the current node, which is beneficial to flexibly processing ARXML files of different structures and levels and enhancing the flexibility and expansibility of the system; generating a service signal according to the extracted and parsed information and sending the service signal as a subscription request to a server; obtaining a processing result of the subscription request; if the processing result is a subscription failure, obtaining error information or a state code returned by the server to help the terminal respond to problems in time and take corresponding measures, thereby improving the fault tolerance, stability, and reliability of the terminal.

[0108] Referring to FIG. 2, in some embodiments, the step S106 can include but is not limited to steps S201 to S202.

[0109] In step S201, a response of a server is listened to, and a processing result of a subscription request returned by the server is obtained.

[0110] In step S201 of some embodiments, a terminal obtains a processing result of a subscription request returned by a server by listening to a response of the server.

[0111] In the present embodiment, a response of a server is listened to, and a processing result of a subscription request returned by the server is obtained, which prepares for subsequent processing of subscription success and subscription failure.

[0112] In step S202, if the processing result is a subscription success, registered service information returned by the server is obtained.

[0113] Specifically, the registered service information includes all registered service information of the server. The registered service information indicates that these services have been registered in the network and can be discovered, subscribed, and used by other nodes. The registered service information includes a data type, a method identifier, and a group identifier.

[0114] In step S202 of some embodiments, if the processing result is a subscription success, registered service information returned by the server is obtained, and it is verified whether the registered service information contains a subscription request sent by the terminal. If yes, the service has been subscribed, and if no, the subscription request is updated according to the method identifier and the group identifier.

[0115] In the embodiment, if the processing result is that the subscription succeeds, the terminal can discover available services according to the server by obtaining the registered service information returned by the server, so as to realize dynamic service discovery.

[0116] Referring to FIG. 3, in some embodiments, the server returns error information, and step S107 can include but is not limited to steps S301-S302:

[0117] In step S301, if the processing result is that the subscription fails, error information returned by the server is obtained.

[0118] In step S301 of some embodiments, the server returns error information.

[0119] In step S302, an error processing manner is determined according to an error type.

[0120] Specifically, the error information includes the error type.

[0121] In step S302 of some embodiments, the error type can include but is not limited to network connection error, service unavailable, authentication failure, parameter error, and timeout.

[0122] Optionally, according to the error type, the error processing manner is determined, and a corresponding error processing strategy is formulated.

[0123] In some embodiments, the corresponding error processing strategy is formulated, which is beneficial to reduce error repetition.

[0124] In the embodiment, the error processing manner is determined according to the error type, which is beneficial to error processing, improves program stability, enhances user experience, and reduces error repetition probability.

[0125] Referring to FIG. 4, in some embodiments, the server returns a status code, and step S107 can include but is not limited to steps S401-S403:

[0126] In step S401, if the processing result is that the subscription fails, a status code returned by the server is obtained.

[0127] In step S401 of some embodiments, the server returns the status code. Specifically, the status code does not include the error type.

[0128] In step S402, an error type is determined according to the status code.

[0129] In step S402 of some embodiments, the error type is determined according to the status code by referring to a configuration document.

[0130] It should be noted that the configuration document is pre-set by relevant personnel.

[0131] Step S403, determining the error handling mode according to the error type.

[0132] In step S403 of some embodiments, the error type can include but is not limited to network connection error, service unavailable, authentication failure, parameter error, server failure and request timeout.

[0133] In some embodiments, the document parsing method is applied to the client, the server adopts the server side, the client communicates with the server, and the client server communication schematic diagram is shown in FIG. 5, wherein 501 represents the client, and 502 represents the server. The client flow schematic diagram is shown in FIG. 6, and the method in FIG. 6 includes but is not limited to steps S601 to S611:

[0134] Step S601, reading the ARXML file content through the parsing library, and parsing the read content into a tree structure of XML document.

[0135] In step S601 of some embodiments, a Python library for parsing XML files is imported, for example, xml.etree.ElementTree; a function or method is created to perform the parsing and processing of ARXML files; and the file operation function of Python is used to open the ARXML file.

[0136] Further, the ARXML file content is read using the parsing library and parsed into a tree structure of XML document. Wherein, the parse() function or similar method can be used.

[0137] Step S602, obtaining the root node of the tree structure, and taking the root node as the current node.

[0138] In step S602 of some embodiments, the root node is obtained from the parsed XML document, which is the starting point of the XML tree structure.

[0139] Step S603, extracting and parsing the information of the current node, and storing the information of the current node.

[0140] In step S603 of some embodiments, the label, attribute and text content of each node are extracted, and the information is processed or stored as needed.

[0141] For each node, its attributes are parsed and stored as key-value pairs or other data structures for subsequent processing and analysis. The attributes of ARXML contain a lot of information, such as data type, SWC runnable, port, type mapping, signal node, communication ID, method identifier (Method ID) and group identifier (GROUP ID) and other information. In this embodiment, the signal, ID, period and other information related to Ethernet communication are extracted.

[0142] Step S604, if the current node has child nodes, the child nodes are taken as the current nodes, and the step of extracting and parsing the current nodes and storing the information of the current nodes is returned.

[0143] In step S604 of some embodiments, the nodes and child nodes of the XML tree are traversed in a loop or recursive manner.

[0144] Step S605, converting the extracted node information into a target data structure.

[0145] In step S605 of some embodiments, the extracted node information is organized into a target data structure, such as a list, a dictionary, an object, etc., according to the requirements of parsing and the data structure.

[0146] Step S606, generating a service signal according to the information extracted and parsed, and sending the service signal as a subscription request to the server.

[0147] Optionally, a data model is created according to the extracted node information.

[0148] In step S606 of some embodiments, a service signal is generated according to the information extracted and parsed, and the service signal is sent as a subscription request to the SD server (i.e., the server) to request subscription of a specific service. Exemplarily, a schematic diagram of the SD server is shown in FIG. 7, where "SWC" represents "Software Component" (software component), "BSWM" represents "Basic Software Module" (basic software module), SD represents the SD server, and "SOAD" represents "Service-Oriented Architecture Design" (service-oriented architecture design).
