#DOMHandler-Daily

The DOM handler (formally known as DefaultHandler) creates a tree containing all nodes of a page. The tree may be manipulated using the DOMUtils library.

Custom version to handle Twig tags in elements.

##Usage

1var handler = new DomHandler([ <func> callback(err, dom), ] [ <obj> options ]);
2// var parser = new Parser(handler[, options]);

##Example

1var htmlparser = require("htmlparser2");
2var rawHtml = "Xyz <script language= javascript>var foo = '<<bar>>';< /  script><!--<!-- Waah! -- -->";
3var handler = new htmlparser.DomHandler(function (error, dom) {
4    if (error)
5    	[...do something for errors...]
6    else
7    	[...parsing done, do something...]
8        console.log(dom);
9});
10var parser = new htmlparser.Parser(handler);
11parser.write(rawHtml);
12parser.done();

Output:

1[{
2    data: 'Xyz ',
3    type: 'text'
4}, {
5    type: 'script',
6    name: 'script',
7    attribs: {
8    	language: 'javascript'
9    },
10    children: [{
11    	data: 'var foo = \'<bar>\';<',
12    	type: 'text'
13    }]
14}, {
15    data: '<!-- Waah! -- ',
16    type: 'comment'
17}]

##Option: normalizeWhitespace Indicates whether the whitespace in text nodes should be normalized (= all whitespace should be replaced with single spaces). The default value is "false".

The following HTML will be used:

1<font>
2	<br>this is the text
3<font>

###Example: true

1[{
2    type: 'tag',
3    name: 'font',
4    children: [{
5    	data: ' ',
6    	type: 'text'
7    }, {
8    	type: 'tag',
9    	name: 'br'
10    }, {
11    	data: 'this is the text ',
12    	type: 'text'
13    }, {
14    	type: 'tag',
15    	name: 'font'
16    }]
17}]

###Example: false

1[{
2    type: 'tag',
3    name: 'font',
4    children: [{
5    	data: '\n\t',
6    	type: 'text'
7    }, {
8    	type: 'tag',
9    	name: 'br'
10    }, {
11    	data: 'this is the text\n',
12    	type: 'text'
13    }, {
14    	type: 'tag',
15    	name: 'font'
16    }]
17}]

##Option: withStartIndices Indicates whether a startIndex property will be added 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".
