## Usage

`@hoangcung1804npm/totam-perferendis-nam` 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.

```js
import * as @hoangcung1804npm/totam-perferendis-nam from "@hoangcung1804npm/totam-perferendis-nam";

const parser = new @hoangcung1804npm/totam-perferendis-nam.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 stitch 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/hoangcung1804npm/totam-perferendis-nam/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:

```js
import { WritableStream } from "@hoangcung1804npm/totam-perferendis-nam/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
import * as @hoangcung1804npm/totam-perferendis-nam from "@hoangcung1804npm/totam-perferendis-nam";

const dom = @hoangcung1804npm/totam-perferendis-nam.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 Feeds

`@hoangcung1804npm/totam-perferendis-nam` makes it easy to parse RSS, RDF and Atom feeds, by providing a `parseFeed` method:

```javascript
const feed = @hoangcung1804npm/totam-perferendis-nam.parseFeed(content, options);
```

## 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)):

## 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.
`@hoangcung1804npm/totam-perferendis-nam` was rewritten multiple times and, while it maintains an API that's mostly compatible with `htmlparser`, 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` was renamed to clarify its purpose (to `DomHandler`). The old name is still available when requiring `@hoangcung1804npm/totam-perferendis-nam` and your code should work as expected.

The `RssHandler` was replaced with a `getFeed` function that takes a `DomHandler` DOM and returns a feed object. There is a `parseFeed` helper function that can be used to parse a feed from a string.
