domhandler

domhandler

The DOM handler creates a tree containing all nodes of a page. The tree can be manipulated using the domutils or cheerio libraries and rendered using dom-serializer .

Usage

const handler = new DomHandler([ <func> callback(err, dom), ] [ <obj> options ]); // const parser = new Parser(handler[, options]);

Available options are described below.

Example

const { Parser } = require("htmlparser2"); const { DomHandler } = require("domhandler"); const rawHtml = "Xyz <script language= javascript>var foo = '<<bar>>';</script><!--<!-- Waah! -- -->"; const handler = new DomHandler((error, dom) => { if (error) { // Handle error } else { // Parsing completed, do something console.log(dom); } }); const parser = new Parser(handler); parser.write(rawHtml); parser.end();

Output:

[ { data: "Xyz ", type: "text", }, { type: "script", name: "script", attribs: { language: "javascript", }, children: [ { data: "var foo = '<bar>';<", type: "text", }, ], }, { data: "<!-- Waah! -- ", type: "comment", }, ];

Option: withStartIndices

Add a startIndex property to nodes. When the parser is used in a non-streaming fashion, startIndex is an integer indicating the position of the start of the node in the document. The default value is false.

Option: withEndIndices

Add an endIndex property to nodes. When the parser is used in a non-streaming fashion, endIndex is an integer indicating the position of the end of the node in the document. The default value is false.
