Network data transmission method based on extensive makeup language (XML)

Abstract

The invention discloses a network data transmission method based on an extensive makeup language (XML). The method comprises the following steps: A, to-be-transmitted initial data are converted into a standard XML file by a data transmitting end; B, each data item in the standard XML file is converted to retrenching type XML data in a form of binary data according to a preset transformational rule; and C, the retrenching type XML data are transmitted to a receiving end through a network. The network data transmission method is capable of reducing occupation of network broad band and improving transmission efficiency.

Description

technical field [0001] The invention relates to network data transmission technology, in particular to a network data transmission method based on Extended Markup Language (XML). Background technique [0002] Extensible Markup Language (XML) is a simple data storage language that uses a series of simple tags to describe data, store and transmit data in a structured form. Because of its good scalability, separation of content and form, and good value preservation, it is often used in network data transmission. [0003] At present, XML-based network data transmission methods such as figure 1 shown, including the following steps: [0004] Step 101, the data sending end tags the data content to be transmitted according to the XML format specification, and generates a standard XML format file. [0005] Step 102, transmit the generated standard XML format file to the data receiving end through the network. [0006] Step 103, the data receiver parses the standard XML format fil...

Problems solved by technology

[0007] However, for good readability and editability, XML tags and data content directly use ASCII text encoding, so there is a lot of redundant data, the content is not concise enough, and the file size is large

Even if the transmission volume can be reduced by compression / reduction during the transmission process, it is at the cost of losing part of the CPU processing speed

Therefore, in network data transmission, using XML directly will waste bandwidth and reduce transmission efficiency.

[0008] In addition, after the remote destination node receives the network data, it also needs to consume a lot of CPU resources to convert the ASCII text data into binary coded data in the process of parsing the XML format file (most computer application systems use binary code to process data). )
