parserInternals		API documentation		The XML C parser and toolkit of Gnome	relaxng

allows to compile and test pattern expressions for nodes either in a tree or based on a parser state.

Function: xmlFreePattern

void	xmlFreePattern			(xmlPatternPtr comp)

Free up the memory allocated by @comp

Function: xmlFreePatternList

void	xmlFreePatternList		(xmlPatternPtr comp)

Free up the memory allocated by all the elements of @comp

Function: xmlFreeStreamCtxt

void	xmlFreeStreamCtxt		(xmlStreamCtxtPtr stream)

Free the stream context

Function: xmlPatternFromRoot

int	xmlPatternFromRoot		(xmlPatternPtr comp)

Check if the pattern must be looked at from the root.

Function: xmlPatternGetStreamCtxt

xmlStreamCtxtPtr	xmlPatternGetStreamCtxt	(xmlPatternPtr comp)

Get a streaming context for that pattern Use xmlFreeStreamCtxt to free the context.

Function: xmlPatternMatch

int	xmlPatternMatch			(xmlPatternPtr comp, 
					 xmlNodePtr node)

Test wether the node matches the pattern

Function: xmlPatternMaxDepth

int	xmlPatternMaxDepth		(xmlPatternPtr comp)

Check the maximum depth reachable by a pattern

Function: xmlPatternStreamable

int	xmlPatternStreamable		(xmlPatternPtr comp)

Check if the pattern is streamable i.e. xmlPatternGetStreamCtxt() should work.

Function: xmlPatterncompile

xmlPatternPtr	xmlPatterncompile	(const xmlChar * pattern, 
					 xmlDict * dict, 
					 int flags, 
					 const xmlChar ** namespaces)

Compile a pattern.

Function: xmlStreamPop

int	xmlStreamPop			(xmlStreamCtxtPtr stream)

push one level from the stream.

Function: xmlStreamPush

int	xmlStreamPush			(xmlStreamCtxtPtr stream, 
					 const xmlChar * name, 
					 const xmlChar * ns)

push new data onto the stream. NOTE: if the call xmlPatterncompile() indicated a dictionnary, then strings for name and ns will be expected to come from the dictionary. Both @name and @ns being NULL means the / i.e. the root of the document. This can also act as a reset.

Function: xmlStreamPushAttr

int	xmlStreamPushAttr		(xmlStreamCtxtPtr stream, 
					 const xmlChar * name, 
					 const xmlChar * ns)

push new attribute data onto the stream. NOTE: if the call xmlPatterncompile() indicated a dictionnary, then strings for name and ns will be expected to come from the dictionary. Both @name and @ns being NULL means the / i.e. the root of the document. This can also act as a reset.
