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
javascript const handler = new DomHandler([ <func> callback(err, dom), ] [ <obj> options ]); // const parser = new Parser(handler[, options]);
Available options are described below.
Example
javascript
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:
javascript
[
{
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.
Option: normalizeWhitespace _(deprecated)_
Replace all whitespace with single spaces. The default value is false.
Note: Enabling this might break your markup.
For the following examples, this HTML will be used:
html <font> <br />this is the text <font></font></font>
Example: normalizeWhitespace: true
javascript
[
{
type: "tag",
name: "font",
children: [
{
data: " ",
type: "text",
},
{
type: "tag",
name: "br",
},
{
data: "this is the text ",
type: "text",
},
{
type: "tag",
name: "font",
},
],
},
];Example: normalizeWhitespace: false
javascript
[
{
type: "tag",
name: "font",
children: [
{
data: "\n\t",
type: "text",
},
{
type: "tag",
name: "br",
},
{
data: "this is the text\n",
type: "text",
},
{
type: "tag",
name: "font",
