[![Coverage](http://img.shields.io/coveralls/fb55/htmlparser2.svg?style=flat)](https://coveralls.io/r/fb55/htmlparser2)
The fast & forgiving HTML/XML parser.
## Installation
npm install htmlparser2
A live demo of `htmlparser2` is available [here](https://astexplorer.net/#/2AmVrGuGVJ).
## Ecosystem
| Name | Description |
| ------------------------------------------------------------- | ------------------------------------------------------- |
| [htmlparser2](https://github.com/fb55/htmlparser2) | Fast & forgiving HTML/XML parser |
| [domhandler](https://github.com/fb55/domhandler) | Handler for htmlparser2 that turns documents into a DOM |
| [domutils](https://github.com/fb55/domutils) | Utilities for working with domhandler's DOM |
| [css-select](https://github.com/fb55/css-select) | CSS selector engine, compatible with domhandler's DOM |
| [cheerio](https://github.com/cheeriojs/cheerio) | The jQuery API for domhandler's DOM |
| [dom-serializer](https://github.com/cheeriojs/dom-serializer) | Serializer for domhandler's DOM |
## Usage
`htmlparser2` itself provides a callback interface that allows consumption of documents with minimal allocations.
For a more ergonomic experience, read [Getting a DOM](#getting-a-dom) below.
```javascript
const htmlparser2 = require("htmlparser2");
const parser = new htmlparser2.Parser({
onopentag(name, attributes) {
/*
* This fires when a new tag is opened.
*
* If you don't need an aggregated `attributes` object,
* have a look at the `onopentagname` and `onattribute` events.
*/
if (name === "script" && attributes.type === "text/javascript") {
console.log("JS! Hooray!");
}
},
ontext(text) {
/*
* Fires whenever a section of text was processed.
*
* Note that this can fire at any point within text and you might
* have to stich together multiple pieces.
*/
console.log("-->", text);
},
onclosetag(tagname) {
/*
* Fires when a tag is closed.
*
* You can rely on this event only firing when you have received an
* equivalent opening tag before. Closing tags without corresponding
* opening tags will be ignored.
*/
if (tagname === "script") {
console.log("That's it?!");
}
},
});
parser.write(
"Xyz <script type='text/javascript'>const foo = '<<bar>>';</ script>"
);
parser.end();
```
Output (with multiple text events combined):
```
--> Xyz
JS! Hooray!
--> const foo = '<<bar>>';
That's it?!
```
This example only shows three of the possible events.
Read more about the parser, its events and options in the [wiki](https://github.com/fb55/htmlparser2/wiki/Parser-options).
### Usage with streams
While the `Parser` interface closely resembles Node.js streams, it's not a 100% match.
Use the `WritableStream` interface to process a streaming input:
```javascript
const { WritableStream } = require("htmlparser2/lib/WritableStream");
const parserStream = new WritableStream({
ontext(text) {
console.log("Streaming:", text);
},
});
const htmlStream = fs.createReadStream("./my-file.html");
htmlStream.pipe(parserStream).on("finish", () => console.log("done"));
```
## Getting a DOM
The `DomHandler` produces a DOM (document object model) that can be manipulated using the [`DomUtils`](https://github.com/fb55/DomUtils) helper.
```js
const htmlparser2 = require("htmlparser2");
const dom = htmlparser2.parseDocument(htmlString);
```
The `DomHandler`, while still bundled with this module, was moved to its [own module](https://github.com/fb55/domhandler).
Have a look at that for further information.
## Parsing RSS/RDF/Atom Feeds
```javascript
const feed = htmlparser2.parseFeed(content, options);
```
Note: While the provided feed handler works for most feeds,
you might want to use [danmactough/node-feedparser](https://github.com/danmactough/node-feedparser), which is much better tested and actively maintained.
## Performance
After having some artificial benchmarks for some time, **@AndreasMadsen** published his [`htmlparser-benchmark`](https://github.com/AndreasMadsen/htmlparser-benchmark), which benchmarks HTML parses based on real-world websites.
At the time of writing, the latest versions of all supported parsers show the following performance characteristics on GitHub Actions (sourced from [here](https://github.com/AndreasMadsen/htmlparser-benchmark/blob/e78cd8fc6c2adac08deedd4f274c33537451186b/stats.txt)):
```
htmlparser2 : 2.17215 ms/file ± 3.81587
node-html-parser : 2.35983 ms/file ± 1.54487
html5parser : 2.43468 ms/file ± 2.81501

htmlparser2-dom : 3.09034 ms/file ± 4.77033
html-dom-parser : 3.56804 ms/file ± 5.15621
libxmljs : 4.07490 ms/file ± 2.99869
htmljs-parser : 6.15812 ms/file ± 7.52497
parse5 : 9.70406 ms/file ± 6.74872
htmlparser : 15.0596 ms/file ± 89.0826
html-parser : 28.6282 ms/file ± 22.6652
saxes : 45.7921 ms/file ± 128.691
html5 : 120.844 ms/file ± 153.944
```
## How does this module differ from [node-htmlparser](https://github.com/tautologistics/node-htmlparser)?
In 2011, this module started as a fork of the `htmlparser` module.
`htmlparser2` was rewritten multiple times and, while it maintains an API that's mostly compatible with `htmlparser` in most cases, the projects don't share any code anymore.
The parser now provides a callback interface inspired by [sax.js](https://github.com/isaacs/sax-js) (originally targeted at [readabilitySAX](https://github.com/fb55/readabilitysax)).
As a result, old handlers won't work anymore.
The `DefaultHandler` and the `RssHandler` were renamed to clarify their purpose (to `DomHandler` and `FeedHandler`). The old names are still available when requiring `htmlparser2`, your code should work as expected.

# entities [![NPM version](http://img.shields.io/npm/v/entities.svg)](https://npmjs.org/package/entities) [![Downloads](https://img.shields.io/npm/dm/entities.svg)](https://npmjs.org/package/entities) [![Build Status](http://img.shields.io/travis/fb55/entities.svg)](http://travis-ci.org/fb55/entities) [![Coverage](http://img.shields.io/coveralls/fb55/entities.svg)](https://coveralls.io/r/fb55/entities)
Encode & decode HTML & XML entities with ease & speed.
## How to…
### …install `entities`
npm install entities
### …use `entities`
```javascript
const entities = require("entities");
//encoding
entities.escape("&#38;"); // "&#x26;#38;"
entities.encodeXML("&#38;"); // "&amp;#38;"
entities.encodeHTML("&#38;"); // "&amp;&num;38&semi;"
//decoding
entities.decodeXML("asdf &amp; &#xFF; &#xFC; &apos;"); // "asdf & ÿ ü '"
entities.decodeHTML("asdf &amp; &yuml; &uuml; &apos;"); // "asdf & ÿ ü '"
```
## Performance
This is how `entities` compares to other libraries on a very basic benchmark
(see `scripts/benchmark.ts`, for 10,000,000 iterations):
| Library | `decode` perf | `encode` perf | `escape` perf | Bundle size |
| -------------- | ------------- | ------------- | ------------- | -------------------------------------------------------------------------- |
| entities | 1.418s | 6.786s | 2.196s | ![npm bundle size](https://img.shields.io/bundlephobia/min/entities) |
| html-entities | 2.530s | 6.829s | 2.415s | ![npm bundle size](https://img.shields.io/bundlephobia/min/html-entities) |
| he | 5.800s | 24.237s | 3.624s | ![npm bundle size](https://img.shields.io/bundlephobia/min/he) |
| parse-entities | 9.660s | N/A | N/A | ![npm bundle size](https://img.shields.io/bundlephobia/min/parse-entities) |

## Acknowledgements
This libary wouldn't be possible without the work of these individuals. Thanks
to
- [@mathiasbynens](https://github.com/mathiasbynens) for his explanations
about character encodings, and his library `he`, which was one of the
inspirations for `entities`
- [@inikulin](https://github.com/inikulin) for his work on optimized tries for
decoding HTML entities for the `parse5` project
- [@mdevils](https://github.com/mdevils) for taking on the challenge of
producing a quick entity library with his `html-entities` library.
`entities` would be quite a bit slower if there wasn't any competition.
Right now `entities` is on top, but we'll see how long that lasts!
