XML -- an XML parser

Description

This experimental and tentative package provides an interface to the library libxml2 (see http://www.xmlsoft.org/), which is a parser for XML files (see http://en.wikipedia.org/wiki/XML). The package offers two ways of representing the result: as an object of class LibxmlNode, which is a pointer to the internal structure created and accessed by the library; or as a hashtable of class XMLnode (which currently represents only elements, attributes, and nodes).

This package was written to support the packages OpenMath and SCSCP.
