Macro XML_XML_NAMESPACE

#define XML_XML_NAMESPACE;

This is the namespace for the special xml: prefix predefined in the XML Namespace specification.

Macro xmlChildrenNode

#define xmlChildrenNode;

Macro for compatibility naming layer with libxml1. Maps to "children."

Function type xmlDOMWrapAcquireNsFunction

xmlNsPtr	xmlDOMWrapAcquireNsFunction	(xmlDOMWrapCtxtPtr ctxt, 
						 xmlNodePtr node, 
						 const xmlChar * nsName, 
						 const xmlChar * nsPrefix)

A function called to acquire namespaces (xmlNs) from the wrapper.

`ctxt`:	a DOM wrapper context
`node`:	the context node (element or attribute)
`nsName`:	the requested namespace name
`nsPrefix`:	the requested namespace prefix
`Returns`:	an xmlNsPtr or NULL in case of an error.

Function type xmlDeregisterNodeFunc

void	xmlDeregisterNodeFunc		(xmlNodePtr node)

Signature for the deregistration callback of a discarded node

node: the current node

Function type xmlRegisterNodeFunc

void	xmlRegisterNodeFunc		(xmlNodePtr node)

Signature for the registration callback of a created node

node: the current node

xmlAddChild ()

xmlNodePtr	xmlAddChild		(xmlNodePtr parent, 
					 xmlNodePtr cur)

Add a new node to @parent, at the end of the child (or property) list merging adjacent TEXT nodes (in which case @cur is freed) If the new node is ATTRIBUTE, it is added into properties instead of children. If there is an attribute with equal name, it is first destroyed. All tree manipulation functions can safely move nodes within a document. But when moving nodes from one document to another, references to namespaces in element or attribute nodes are NOT fixed. In this case, you MUST call xmlReconciliateNs after the move operation to avoid memory errors.

`parent`:	the parent node
`cur`:	the child node

xmlUnlinkNode ()

void	xmlUnlinkNode			(xmlNodePtr cur)

Unlink a node from it's current context, the node is not freed If one need to free the node, use xmlFreeNode() routine after the unlink to discard it. Note that namespace nodes can't be unlinked as they do not have pointer to their parent.

cur: the node

xmlUnsetNsProp ()

int	xmlUnsetNsProp			(xmlNodePtr node, 
					 xmlNsPtr ns, 
					 const xmlChar * name)

Remove an attribute carried by a node.

`node`:	the node
`ns`:	the namespace definition
`name`:	the attribute name
`Returns`:	0 if successful, -1 if not found

xmlUnsetProp ()

int	xmlUnsetProp			(xmlNodePtr node, 
					 const xmlChar * name)

Remove an attribute carried by a node. This handles only attributes in no namespace.

`node`:	the node
`name`:	the attribute name
`Returns`:	0 if successful, -1 if not found

xmlValidateNCName ()

int	xmlValidateNCName		(const xmlChar * value, 
					 int space)

Check that a value conforms to the lexical space of NCName

`value`:	the value to check
`space`:	allow spaces in front and end of the string
`Returns`:	0 if this validates, a positive error code number otherwise and -1 in case of internal or API error.

xmlValidateNMToken ()

int	xmlValidateNMToken		(const xmlChar * value, 
					 int space)
