DESCRIPTION

The Document Class is in most cases the result of a parsing process. But sometimes it is necessary to create a Document from scratch. The DOM Document Class provides functions that conform to the DOM Core naming style.

It inherits all functions from XML::LibXML::Node as specified in the DOM specification. This enables access to the nodes besides the root element on document level - a DTD for example. The support for these nodes is limited at the moment.

While generally nodes are bound to a document in the DOM concept it is suggested that one should always create a node not bound to any document. There is no need of really including the node to the document, but once the node is bound to a document, it is quite safe that all strings have the correct encoding. If an unbound text node with an ISO encoded string is created (e.g. with $CLASS->new()), the toString function may not return the expected result.

To prevent such problems, it is recommended to pass all data to XML::LibXML methods as character strings (i.e. UTF-8 encoded, with the UTF8 flag on).

METHODS

Many functions listed here are extensively documented in the DOM Level 3 specification (http://www.w3.org/TR/DOM-Level-3-Core/). Please refer to the specification for extensive documentation.
