## What it is
Nokogiri is a Ruby library for parsing, querying, modifying, and generating XML and HTML documents, built on native parsers like libxml2, libgumbo, and xerces. It supports DOM, SAX, and push parsing, XPath 1.0 and CSS3 selector search, XSD validation, XSLT transformation, and a Builder DSL.

## Use cases
- parse html from a webpage in ruby
- scrape data from html tables
- query xml documents with xpath
- validate xml against an xsd schema
- transform xml with xslt
- build and generate xml documents in ruby
- extract links from an html page

## When to choose
- you need fast, standards-compliant XML/HTML parsing in Ruby or JRuby
- you want XPath or CSS selector querying of documents
- you need secure-by-default parsing of untrusted documents
- you need SAX or streaming parsing for large documents

## When to avoid
- you are not working in Ruby
- you need a lenient, forgiving scraper for badly broken HTML beyond what libgumbo handles
- you need XPath 2.0+ features (only XPath 1.0 is supported)

## Facets
- artifact type: library
- maturity: stable
- function: parser, web-scraping, serialization
- domain: parsers, web-development, developer-tools
- platform: ruby, jvm, windows, cross-platform
- tags: xml, html, html5, xpath, css-selectors, xslt, sax-parser, dom, libxml2, ruby-gem, schema-validation, linux, macos
