Detailed Description

Generic node type in an XML or HTML tree.

This is used for

XML_ELEMENT_NODE
XML_TEXT_NODE
XML_CDATA_SECTION_NODE
XML_ENTITY_REF_NODE
XML_PI_NODE
XML_COMMENT_NODE
XML_DOCUMENT_FRAG_NODE
XML_XINCLUDE_START_NODE
XML_XINCLUDE_END_NODE

Other node types have a different struct layout than xmlNode, see xmlElementType. Except for XML_NAMESPACE_DECL all nodes share the following members at the same offset:

_private
type (also for XML_NAMESPACE_DECL)
name
children
last
parent
next
prev
doc

xmlNode and xmlAttr also share the ns member.
