## What it is
htmlparser2 is a fast, forgiving HTML and XML parser for JavaScript and TypeScript, offering a low-allocation callback interface as well as DOM output via its ecosystem packages. It prioritizes speed over strict HTML spec compliance, making it the engine behind tools like cheerio.

## Use cases
- parse html from web pages in node
- extract links and text from html documents
- parse xml feeds like rss and atom
- scrape websites with cheerio-style selectors
- stream-parse large html documents with minimal memory
- build a dom tree from malformed html

## When to choose
- you need the fastest html/xml parsing in javascript
- input html may be malformed or non-spec-compliant
- you want a streaming, low-allocation callback-based parser
- you are building scraping or feed-processing tools

## When to avoid
- you need strict HTML5 spec compliance and error correction (use parse5)
- you need a full browser-grade DOM with CSS selector querying out of the box
