A SAX-style streaming parser for XML and HTML written in JavaScript, designed for Node.js but usable in the browser. It emits events for tags, text, and attributes, with a strict XML mode and a lenient HTML-ish mode.

Use cases

• parse xml in node.js
• stream large xml files without loading into memory
• parse rss feeds with slightly broken xml
• event-driven xml parsing in javascript
• extract tags and attributes from xml documents
• tolerant parsing of malformed xml

When to choose

• you need a lightweight, streaming, event-based XML parser
• you're dealing with real-world slightly-broken XML like RSS
• you want to build your own DOM or object model on top of raw XML events
• you need to run in Node.js or the browser with minimal dependencies

When to avoid

• you need a full DOM tree or XPath/XSLT querying
• you need strict standards-compliant XML validation or DTD/XSD schema support
• you need a full HTML parser with browser-like error recovery
• you prefer a tree-building parser API over event callbacks
