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.
