XMLLib osax is a Scripting Addition which implements the XML DOM in AppleScript. Features include:

• opening, validating, closing, saving an XML document
• browsing an XML tree - parents, children, siblings
• searching an XML tree - sending a XPATH request
• editing, creating, removing an XML node
• searching text in an XML node
• applying a XSLT stylesheet
• handling XLinks

XMLLib carries references rather than data or object specifiers, so a script can process large XML documents as fast as if you had been writing a C program - yet, in a more comfortable environment.

Also includes a similar set of commands for Property lists (p-lists). Transparently store AppleScript objects in p-lists. Provide a fast lookup table (or "dictionary", or "associative array") structure.
