XML Query Language (XQL) provides a mechanism for retrieving and interpreting Extensible Markup Language (XML) data. XQL is similar to Extensible Stylesheet Language (XSL) patterns and uses Extensible Markup Language (XML) as a data model. XQL expressions are easily parsed, easy to type, and can be used in a variety of software environments. XQL expressions can be used as part of a URL, in XML or Hypertext Markup Language (HTML) attributes, in programming language strings, and so on. XQL is used in Web browsers, document repositories, XML middleware, Practical Extraction and Report Language (Perl) libraries, and command-line utilities.
