Update and version iteration of the HTMLPARSER framework

Update and version iteration of HTMLPARSER framework HTMLPARSER is an open source framework written by Java to process HTML documents.It provides a powerful analysis and operation of HTML, enabling developers to easily obtain data from HTML or modify HTML. The HTMLPARSER framework has undergone iteration and update of multiple versions, and each version brings better performance, more functions and better stability.The following is an overview of the update of the HTMLPARSER framework and the iteration of the version: 1. HTMLPARSER 1.0: The original version provides a basic HTML parsing function.It can analyze the labels, attributes and texts in HTML, and transform it into an object model with a hierarchical structure. 2. HTMLPARSER 1.1: This version introduces support for the CSS selector.Developers can use the CSS selector to select specific elements in the HTML document to make the analysis and operation HTML more convenient. Example code: String html = "<div id=\"content\">Hello World!</div>"; Parser parser = new Parser(html); NodeList nodeList = parser.parse(new CssSelectorParserVisitor("#content")); String content = nodeList.elementAt(0).toPlainTextString(); System.out.println (Content); // Output: Hello World! 3. HTMLPARSER 2.0: This version introduces integration with other frameworks, such as integration with Spring and JSF.It also provides more analysis options and configurations to enable developers to better control the analysis process. Example code: String html = "<div id=\"content\">Hello World!</div>"; Parser parser = new Parser(html); ParserFeedback feedback = new ParserFeedback(); ParserOptions options = new ParserOptions(); options.setExpressiveness(1.5); options.setFeedback(feedback); parser.setOptions(options); NodeList nodeList = parser.parse(); String content = nodeList.toPlainTextString(); System.out.println (Content); // Output: Hello World! 4. HTMLPARSER 3.0: This version introduces support for HTML5.It can analyze and operate documents that comply with HTML5 specifications and provide some extensions for HTML5 characteristics.At the same time, it also improves the performance and stability of the analyst. Example code: String html = "<div id=\"content\">Hello World!</div>"; Parser parser = new Parser(html); ParserFeedback feedback = new ParserFeedback(); ParserOptions options = new ParserOptions(); options.setLanguage(ParserOptions.HTML5); options.setFeedback(feedback); parser.setOptions(options); NodeList nodeList = parser.parse(); String content = nodeList.toPlainTextString(); System.out.println (Content); // Output: Hello World! The HTMLPARSER framework has continuously improved and improved its functions and performance through continuous updates and version iterations, providing developers with a powerful and flexible HTML analysis and operation tools.Developers can choose the suitable HTMLPARSER version according to their needs, and use the corresponding API to process HTML documents.Whether it is to capture web pages, digging data, or website testing and automation, HTMLPARSER is an excellent framework worth using.
