# XML Functions (lr_xml)

XML is a language for web documents that contain structured information. It enables the identification of structures within the document, and provides the facility to define markup tags and their role. VuGen's web Vusers support web pages containing XML code.

The XML functions are not recorded—you insert them manually into your script.

For general information about using XML functions, see XML function guidelines and queries.
