## What it is
Oga is an XML/HTML parser library for Ruby with a simple API for parsing, modifying, and querying documents via XPath. It requires no system libraries like libxml, using a small native extension for performance and supporting thread-safe parsing.

## Use cases
- parse xml documents in ruby
- parse html without libxml
- query documents with xpath
- scrape html pages in ruby
- stream-parse large xml files
- sax parsing of xml feeds

## When to choose
- you want a pure-Ruby-installable XML/HTML parser without native system dependencies
- you need thread-safe parsing in a multi-threaded app
- you want a lighter alternative to Nokogiri

## When to avoid
- you need maximum parsing performance or extensive Nokogiri feature parity
- you need actively developed software with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, web-scraping
- domain: parsers, web-development, developer-tools
- platform: ruby, cross-platform
- tags: xml-parser, html-parser, xpath, sax, nokogiri-alternative
