} xmlStreamCtxt;

Typedef xmlStreamCtxtPtr

xmlFreePattern ()

void	xmlFreePattern			(xmlPatternPtr comp)

Free up the memory allocated by @comp

xmlFreePatternList ()

void	xmlFreePatternList		(xmlPatternPtr comp)

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

xmlFreeStreamCtxt ()

void	xmlFreeStreamCtxt		(xmlStreamCtxtPtr stream)

Free the stream context

xmlPatternCompileSafe ()

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

Compile a pattern. Available since 2.13.0.

xmlPatternFromRoot ()

int	xmlPatternFromRoot		(xmlPatternPtr comp)

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

xmlPatternGetStreamCtxt ()

xmlStreamCtxtPtr	xmlPatternGetStreamCtxt	(xmlPatternPtr comp)

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

xmlPatternMatch ()

int	xmlPatternMatch			(xmlPatternPtr comp, 
					 xmlNodePtr node)

Test whether the node matches the pattern

xmlPatternMaxDepth ()

int	xmlPatternMaxDepth		(xmlPatternPtr comp)

Check the maximum depth reachable by a pattern

xmlPatternMinDepth ()

int	xmlPatternMinDepth		(xmlPatternPtr comp)

Check the minimum depth reachable by a pattern, 0 mean the / or . are part of the set.

xmlPatternStreamable ()

int	xmlPatternStreamable		(xmlPatternPtr comp)

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

xmlPatterncompile ()

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

Compile a pattern.

xmlStreamPop ()

int	xmlStreamPop			(xmlStreamCtxtPtr stream)

push one level from the stream.

xmlStreamPush ()

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

Push new data onto the stream. NOTE: if the call xmlPatterncompile() indicated a dictionary, 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. Otherwise the function will act as if it has been given an element-node.

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 dictionary, 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. Otherwise the function will act as if it has been given an attribute-node.

xmlStreamPushNode ()

int	xmlStreamPushNode		(xmlStreamCtxtPtr stream, 
					 const xmlChar * name, 
					 const xmlChar * ns, 
					 int nodeType)

Push new data onto the stream. NOTE: if the call xmlPatterncompile() indicated a dictionary, 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. Different from xmlStreamPush() this function can be fed with nodes of type: element-, attribute-, text-, cdata-section-, comment- and processing-instruction-node.

xmlStreamWantsAnyNode ()

int	xmlStreamWantsAnyNode		(xmlStreamCtxtPtr streamCtxt)

Query if the streaming pattern additionally needs to be fed with text-, cdata-section-, comment- and processing-instruction-nodes. If the result is 0 then only element-nodes and attribute-nodes need to be pushed.
