The functional characteristics and advantages of the Jericho HTML DEV framework
The Jericho HTML DEV framework is an open source Java library for parsing and operating HTML documents.This framework provides some functional characteristics, enabling developers to process HTML documents more easily. The following are some of the main functional characteristics and advantages of the framework.
1. HTML analysis: Jericho HTML DEV framework can resolve HTML documents and convert it into a Java object model.Developers can use this model to retrieve and process data in HTML documents.
String html = "<html><body><h1>Hello World!</h1></body></html>";
Source source = new Source(html);
List<Element> headings = source.getAllElements(HTMLElementName.H1);
for (Element heading : headings) {
System.out.println(heading.getTextExtractor().toString());
}
2. DOM operation: This framework provides a powerful and simple API, allowing developers to manipulate HTML documents by programming.Developers can use these APIs to query, add, modify or delete HTML elements.
String html = "<html><body><h1>Hello World!</h1></body></html>";
Source source = new Source(html);
Element body = source.getFirstElement(HTMLElementName.BODY);
Element newHeading = new Element(HTMLElementName.H2);
newHeading.setContent("Welcome to Jericho HTML Dev!");
body.insertChild(newHeading, 0);
System.out.println(source.toString());
3. Text extraction: This framework provides various methods to extract the text content in the HTML document and supports various operations of the text content, such as words, filtering or formatting.
String html = "<html><body><p>Hello <b>World</b>!</p></body></html>";
Source source = new Source(html);
List<TextExtractor> textExtractors = source.getAllTextExtractors();
for (TextExtractor textExtractor : textExtractors) {
System.out.println(textExtractor.toString());
}
String formattedText = source.getRenderer().toString();
System.out.println(formattedText);
4. Character encoding support: Jericho HTML DEV framework can automatically identify and process the character encoding of the HTML document.It can properly handle various character coding and provide methods to analyze and generate HTML documents with different character codes.
String html = "<html><head><meta charset=\"UTF-8\"></head><body>Hello World!</body></html>";
Source source = new Source(html);
String charset = source.getEncoding();
System.out.println(charset);
In short, the Jericho HTML DEV framework is a powerful and easy -to -use HTML processing tool.It provides rich functional features, enabling developers to analyze, operate and extract data in HTML documents more efficiently.Using this framework, developers can easily build HTML -based applications, and can handle various complex HTML documents.
