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.

Field Documentation

_private

void* _private

Application data.

Often used by language bindings.

children

struct _xmlNode* children

First child.

Entity declaration of entity references.

content

xmlChar* content

Content of text, comment, PI nodes.

Sort index for elements after calling xmlXPathOrderDocElems. Content of internal entities for entity references.

doc

struct _xmlDoc* doc

Associated document.

Used to access DTDs, entities, ID tables, dictionary or other document properties. All children of a node share the same document.

name

const xmlChar* name

Name of the node.

• Local name of elements or attributes. As a corner case, this can also contain Names which are invalid QNames in non-namespace-wellformed documents.
• Name of entity references
• Target of processing instructions
• Fixed string for text and comments
• Unused otherwise

parent

struct _xmlNode* parent

Parent node.

NULL for documents or unlinked root nodes.

properties

struct _xmlAttr* properties

First attribute of element.

Also used to store small strings with XML_PARSE_COMPACT.
