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.

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:

<font> <br />this is the text <font></font></font>

Example: normalizeWhitespace: true

[
    {
        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

[
    {
        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",
            },
        ],
    },
];
