QueryPath is a PHP library for working with HTML, XML, and web services that follows the jQuery interface. It provides a simpler way to work with DOM compared to other PHP libraries like DOM and SimpleXML. QueryPath can be used to search, modify, and extract data from XML/HTML files, strings, and URLs. It has been used in various projects and modules like interacting with Drupal. The latest version adds new features and documentation.

• Compact library.
• Functions are short and
mnemonic.

• The power of DOM, but
simpler than SimpleXML
• (Shhh... don’t tell, but it’s
built on the DOM.)
