The following figure presents an overview over the classes of the XML module and their relations.
XML module
The XML module provides classes that allow creation, writing and reading of files in the Extensible Markup Language (XML) format. The central class of the XML module is the abstract GXmlNode base class which represent a node of the XML document. The essential property of GXmlNode is that it may contain a list of GXmlNode objects, allowing creating a complex tree of data structures. Nodes in a XML document may be either elements, comments, some text of a processing instruction. These different node types are implemented by the GXmlElement, GXmlComment, GXmlText and GXmlPI classes, respectively. A special node if the GXmlDocument node which provides the root node of a XML document. This node must exist only once in a XML tree. The XML file is implement by the GXml class which contains one instance of GXmlDocument.
