htmlparser2
htmlparser2 is a Node.js library for parsing HTML and XML documents. It works by building a tree of elements, similar to the Document Object Model (DOM) in web browsers. This allows you to easily traverse and manipulate the structure of the document.
htmlparser2 is a low-level html tree parser but it can still be useful in web scraping as it's a powerful tool for HTML restructuring and serialization.
Example Use
``javascript
const htmlparser = require("htmlparser2");
const parser = new htmlparser.Parser({
onopentag: (name, attribs) => {
console.log(Opening tag: ${name});
},
ontext: (text) => {
console.log(Text: ${text});
},
onclosetag: (name) => {
console.log(Closing tag: ${name}`);
}
}, {decodeEntities: true});
const html = "
Hello, world!
"; parser.write(html); parser.end(); ```
