+# domhandler [![Build Status](https://travis-ci.com/fb55/domhandler.svg?branch=master)](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`.
+
+## 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",
+            },
