# domhandler [](https://travis-ci.com/fb55/domhandler)
|
|
|
|
The DOM handler creates a tree containing all nodes of a page.
|
|
The tree can be manipulated using the [domutils](https://github.com/fb55/domutils)
|
|
or [cheerio](https://github.com/cheeriojs/cheerio) libraries and
|
|
rendered using [dom-serializer](https://github.com/cheeriojs/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`.
