[0056] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.
[0057] In one embodiment, as shown in Figure 1 A text rendering method is provided, and the present embodiment is exemplarily described by taking the method applied to a terminal. It should be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and can be realized through the interaction of the terminal and the server. In the present embodiment, the method includes the following steps:
[0058] In step S110, a target structured document is obtained, and the target structured document is parsed to obtain a target text and at least one style rule matched with the target text.
[0059] Exemplarily, the target structured document is obtained, wherein the target structured document can be a document corresponding to a rendering task in a current scenario. In some examples, the target structured document can be automatically obtained according to the rendering task, or can be obtained by prior configuration. In some examples, the target structured document can include an HTML (HyperText Markup Language) document.
[0060] Optionally, the target structured document is parsed to obtain the target text and the matched style rule. In some examples, a parser can be constructed by using a preset semantic analysis algorithm, and the target structured document is parsed by using the parser to obtain the target text and the corresponding style rule.
[0061] In some possible implementation manners, the parser scans the target structured document line by line, identifies and extracts style labels (such as and tagged wrapped content. For example, for Example text The parser identifies (Paragraph tag), (bold tag), and "example text" within the tag; extract the text information without all tags from the content wrapped by the tag to form the target text; the parser analyzes the style information contained in the tag (including the semantic style brought by the tag itself and the explicitly defined style attributes) to form the corresponding style rule; record the association of each target text and the corresponding style rule to form a mapping, for example, "example text" may be associated with a paragraph style of the label and a bold style of the label, the parser can store the association as a correspondence of "text node→[paragraph style, bold style]". In some examples, one target text can correspond to one or more style rules, which can be determined according to the target structured document in the actual application scenario.
[0062] In step S120, a style instruction corresponding to the style rule is determined according to a style attribute of the style rule, the style attribute including at least one of a global style attribute and a differential style attribute.
[0063] For example, the corresponding style instruction is determined according to the style attribute of the style rule. In some examples, the style rule can include a basic style rule applied to the entire target text, i.e., a style rule of a global style attribute; the style rule can also include a differential style rule applied to part of the content in the target text, i.e., a style rule of a local style attribute.
[0064] Optionally, different style rules can be rendered by different components, and different components can correspond to different types of style instructions. According to the style attribute of the style rule, the type of the style instruction corresponding to the style rule is determined, and the style instruction is generated.
[0065] In step S130, the target text is rendered by using the components corresponding to the style instructions respectively, to obtain initial rendering texts, and the initial rendering texts are merged to obtain a target rendering text.
[0066] For example, the target text is rendered by using the components corresponding to the style instructions. In some examples, when the style rule corresponding to the target text includes multiple style rules of different style attributes, the target text is rendered by using different components respectively to obtain multiple initial rendering texts. The initial rendering texts are merged to obtain the final target rendering text.
[0067] In the text rendering, the target structured document is obtained and parsed to obtain the target text and the corresponding style rule. According to the style attribute of the style rule, the corresponding style instruction is determined, the initial rendering text is obtained by rendering the components corresponding to the style instruction respectively, and the target rendering text is obtained by merging the initial rendering text. Therefore, the text rendering is quickly and accurately realized, and the text rendering effect is ensured. In the rendering, different style instructions are determined for different style attributes of the style rule, so that the corresponding components can be used for rendering. In the case of limited rendering function of the rendering component, the rendering of the complex style of the text is realized by generating the style instruction in a targeted manner, the global style rendering and the differential style rendering are ensured to be realized, and more application scenarios are applicable. The requirement for the component required for rendering is low. According to the embodiment of the present disclosure, the complex style rendering of the text can be realized by using a lightweight component, and the rendering effect is effectively improved.
[0068] In one embodiment, as shown in Figure 2 The parsing of the target structured document obtains the target text and at least one style rule matched with the target text.
[0069] In step S111, the target structured document is parsed to extract the style label in the target structured document and the text data corresponding to the style label.
[0070] In step S112, the target text and the style rule matched with the target text are generated according to the style label and the text data.
[0071] For example, when determining the target text and the style rule, the target structured document is parsed to extract the style label in the target structured text and the text data corresponding to the style label. In some examples, the target structured document usually includes two parts of content. One part is pure text data, that is, the actual literal content in the document, such as paragraph text, title text, etc. The other part is the associated style rule, wherein the style rule can be defined by a style label or a cascading style sheet, including but not limited to style information such as font size, color, bold, indentation, etc. The style label and the corresponding text data can be obtained by semantic parsing.
[0072] Optionally, the target text is obtained according to the text data, the corresponding style rule is obtained according to the style label, and the target text and the style rule matched with the target text are generated based on the corresponding relationship between the text data and the style label.
[0073] The embodiment of the present disclosure analyzes a target structured document, extracts style tags and text data, generates target text and style rules, and uses a semantic analysis method to quickly and accurately extract style tags and text data from the target structured document, and then generate target text and style rules, thereby improving text rendering efficiency, ensuring the accuracy of the generated target text and style rules, and improving rendering effect.
[0074] In one embodiment, as shown in Figure 3 The method comprises the following steps:
[0075] S121, generating a standardized style feature vector corresponding to the style rule;
[0076] S122, according to the style attribute of the style rule, mapping the standardized style feature vector into a style instruction.
[0077] Exemplarily, according to the style rule, a standardized style feature vector corresponding to the style rule is generated. In some examples, the style attributes of different units are converted into a unified unit (such as converting em, rem, % and the like into px), all color representations (such as red, #FF0000, rgb(255,0,0)) are uniformly converted into ARGB (Alpha Red Green Blue, Alpha channel + red green blue color model) format (such as #FFFF0000), font names are mapped to standard fonts supported by the system (such as mapping "Microsoft YaHei" to "sans-serif"), redundant units are removed (such as font-size: 16px→16), and are normalized to integers or floating-point numbers; text style dimension information, layout attribute dimension information, spacing attribute dimension information, and special effect dimension information are extracted from the preprocessed style rule; the extracted information is converted into a fixed-length numerical vector, each dimension corresponds to a position in the vector; each dimension in the vector is normalized to ensure that all values are within a unified range (such as [0,1]), wherein the value of the data attribute is mapped to [0,1] through linear scaling (such as value / max_value); the value of the enumeration attribute is converted into a binary vector using One-Hot Encoding (such as alignment left=1,0,0; center=0,1,0; right=0,0,1); for undefined style attributes, use default values to fill in special values (such as -1) in the vector; and generate a standardized style feature vector.
[0078] Optionally, based on the style attributes corresponding to the style rules, the corresponding style instruction type is determined, and the standardized style feature vector is mapped to the style instruction corresponding to that style instruction type.
[0079] In this embodiment, a standardized style feature vector is generated according to style rules and mapped to style instructions. This enables the style rules to be quickly and accurately converted into style instructions that the component can process. Based on style attributes, the mapping is implemented to convert different style attributes into different style instructions. Text rendering can also be achieved in complex style scenarios, making it suitable for more application scenarios.
[0080] In one embodiment, mapping the standardized style feature vector to style instructions based on the style attributes of the style rules includes:
[0081] When the style attribute of the style rule is a global style attribute, based on the parsing method corresponding to the global rendering component, the standardized style feature vector is mapped to a global style instruction that the global rendering component can parse; and / or,
[0082] When the style attribute of the style rule is a differential style attribute, the standardized style feature vector is mapped to a differential style instruction that can be parsed by the target differential rendering component based on the parsing method corresponding to the target differential rendering component.
[0083] For example, when the style attribute of a style rule is a global style, the corresponding style instruction type is determined based on the parsing method of the global rendering component, and the standardized style feature vector is mapped to a global style instruction that the global rendering component can parse. In some examples, the style instruction type corresponding to the style rule of a global style may include a global style instruction, and the interface parameters corresponding to the global style instruction match the global rendering component.
[0084] Optionally, when the style attribute of the style rule is a difference style attribute, the corresponding style instruction type is determined based on the parsing method of the target difference rendering component, and the standardized style feature vector is mapped to a difference style instruction that the target difference rendering component can parse. In some examples, the style instruction type corresponding to the style rule of the difference style may include a difference style instruction, and the interface parameters corresponding to the difference style instruction match the target difference rendering component. In some examples, the target difference rendering component may be a sub-component nested within a global rendering component, which can be used to implement local rendering within text.
[0085] In this embodiment, global style attributes and differential style attributes are mapped to corresponding style instructions respectively. Style instructions are mapped in a targeted manner for different style rules. Even in the case of lightweight components, style instructions can be quickly and accurately identified and text rendered.
[0086] In an embodiment, the parsing the target structured document to obtain a target text and at least one style rule matched with the target text comprises:
[0087] parsing the target structured document to obtain a target text and at least one candidate style rule matched with the target text;
[0088] determining a weight score of the candidate style rule according to style information corresponding to the candidate style rule;
[0089] determining a style rule matched with the target text from the candidate style rules according to the weight score.
[0090] Exemplarily, style conflict detection and merging is performed through style weight calculation. A target structured text is parsed to obtain a candidate style rule matched with a target text, and the candidate style rule can include one or more. A weight score of the candidate style rule is determined according to style information corresponding to the candidate style rule, and the weight score can be determined after weighting based on scores in different dimensions. The weight score can be determined according to an actual application scenario.
[0091] Optionally, a style rule matched with the target text is determined based on the weight score. In some examples, the higher the weight score is, the higher the priority of the corresponding candidate style rule is. In the case of conflict between the candidate style rules, the candidate style rule with the higher weight score is determined as the style rule corresponding to the target text.
[0092] In the embodiments of the present disclosure, the weight score is determined based on the style information, and the style rules are screened, so that redundant style rules can be quickly and accurately screened out, the accuracy and reliability of the finally obtained style rules are ensured, the text rendering effect is improved, the problem of rendering failure caused by style conflicts or repetition is avoided, and the present disclosure is suitable for more application scenarios.
[0093] In an embodiment, the determining the weight score of the candidate style rule according to the style information corresponding to the candidate style rule comprises:
[0094] determining an element score corresponding to the candidate style rule according to an element type corresponding to the candidate style rule; determining an inheritance level score corresponding to the candidate style rule according to source information corresponding to the candidate style rule; determining a specificity score corresponding to the candidate style rule according to a selector type corresponding to the candidate style rule; and determining a declaration order score corresponding to the candidate style rule according to a declaration time corresponding to the candidate style rule;
[0095] Based on the element score, the inheritance hierarchy score, the specificity score, and the declaration order score, a weight score of the candidate style rule is determined.
[0096] For example, an element score is assigned based on the element type associated with the style rule (e.g., block-level elements 、 with inline elements , a weight difference, the core content element weight is higher than the auxiliary element); determining an inheritance level score based on source information corresponding to the candidate rule, wherein a directly applied style weight is higher than an inherited style, for example, a parent node sets "color:black", but the current node directly sets "color:red", then the "red" weight is higher; determining a specificity score according to a selector type, in some examples, for a style rule defined by a CSS (Cascading Style Sheets) selector, a specificity score is assigned according to the selector type, for example, an ID selector #id> a class selector.class> an element selector p> a wildcard, the higher the specificity, the higher the specificity score; determining a declaration order score based on a declaration time corresponding to the candidate style rule, wherein the style rules are sorted according to the declaration time, and the style rule declared later has a higher weight than the style rule declared earlier.
[0097] Optionally, the weight score of the candidate style rule is determined according to the element score, the inheritance level score, the specificity score and the declaration order score. In some possible implementations, a weight coefficient is set for each of the four dimensions, and the weighted weight score is calculated for the candidate style rules in conflict. Among the candidate style rules in conflict, the style rule with the highest weight score is determined as the final effective style, that is, the style rule corresponding to the target text, and the remaining conflicting styles are discarded.
[0098] In some examples, the effective style retained after the conflict is processed is combined with the non-conflicting candidate style rules of the target text to form all the style rules corresponding to the target text.
[0099] The embodiments of the present disclosure determine scores in multiple dimensions based on the element type, the source information, the selector type and the specificity score, and finally obtain the weight score, which further improves the accuracy and reliability of the weight score, ensures the accuracy of the selected style rules, improves the text rendering effect, reduces the data processing workload during text rendering, and improves the text rendering efficiency.
[0100] Figure 4 To show a flowchart of a text rendering according to an example embodiment, refer to Figure 4 As shown, the target structured document can include an HTML (HyperText Markup Language) document, and when text rendering is performed, an HTML tag parser is constructed, the HTML document is decoupled into a pure text data set (i.e., target text) and an associated style rule set (i.e., corresponding style rules) through semantic analysis, and a one-to-many mapping relationship between a text node and a style rule is established; a style optimization processor is designed, and the following operations are performed on the style rule set: a) style conflict detection and merging through style weight calculation and cascade rules, b) generation of a standardized style feature vector, and establishment of a one-to-one correspondence between a text node and a style feature; a dynamic style mapping engine is created, the standardized style feature vector is converted into a style instruction set of a target platform based on style specifications of a cross-platform UI (User Interface) framework, and the following mapping relationships are achieved: a) mapping of a common style attribute (i.e., global style) to a platform basic text Text component (i.e., global rendering component), b) mapping of a differential style attribute to a platform Span component (i.e., target differential rendering component); rendering is achieved, and the same source style Span component is instantiated and reused based on a batch processing mechanism of style similarity.
[0101] In some examples, the conflict processing adopts a multi-dimensional priority algorithm, contains a four-tuple evaluation model of element weight, inheritance level, selector specificity and declaration order, and determines the final effective style through linear weighting calculation. In some examples, the dynamic style mapping engine contains a bidirectional binding module, supports dynamic modification of the mapped style through a reactive programming interface, and the modification operations include: a) real-time addition, deletion and modification operations of style attributes, b) dynamic mounting and unloading of event listeners.
[0102] Through the embodiment, intelligent parsing of HTML text to component-parsable instructions is achieved, and pure text content and associated style attributes are accurately extracted; a style optimization algorithm is adopted, and rendering performance is significantly improved through extraction and deduplication processing; dynamic interaction capability is supported, complete style management and event processing APIs (Application Programming Interface) are provided in addition to basic rendering; and an efficient rendering scheme is achieved based on a lightweight Text control.
