    domhandler Build Status

    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",
                },
            ],
        },
    ];
