Description

Function: xmlXPtrNewRangePoints

xmlXPathObjectPtr	xmlXPtrNewRangePoints	(xmlXPathObjectPtr start, 
				 xmlXPathObjectPtr end)

Create a new xmlXPathObjectPtr of type range using 2 Points

start:the starting point
end:the ending point
Returns:the newly created object.

Function: xmlXPtrBuildNodeList

xmlNodePtr	xmlXPtrBuildNodeList	(xmlXPathObjectPtr obj)

Build a node list tree copy of the XPointer result. This will drop Attributes and Namespace declarations.

obj:the XPointer result from the evaluation.
Returns:an xmlNodePtr list or NULL. the caller has to free the node tree.

Function: xmlXPtrEval

xmlXPathObjectPtr	xmlXPtrEval	(const xmlChar * str, 
				 xmlXPathContextPtr ctx)

Evaluate the XPath Location Path in the given context.

str:the XPointer expression
ctx:the XPointer context
Returns:the xmlXPathObjectPtr resulting from the evaluation or NULL. the caller has to free the object.

Function: xmlXPtrNewCollapsedRange

xmlXPathObjectPtr	xmlXPtrNewCollapsedRange	(xmlNodePtr start)

Create a new xmlXPathObjectPtr of type range using a single nodes

start:the starting and ending node
Returns:the newly created object.

Function: xmlXPtrNewLocationSetNodeSet

xmlXPathObjectPtr	xmlXPtrNewLocationSetNodeSet	(xmlNodeSetPtr set)

Create a new xmlXPathObjectPtr of type LocationSet and initialize it with all the nodes from @set

set:a node set
Returns:the newly created object.

Function: xmlXPtrNewRangePointNode

xmlXPathObjectPtr	xmlXPtrNewRangePointNode	(xmlXPathObjectPtr start, 
				 xmlNodePtr end)

Create a new xmlXPathObjectPtr of type range from a point to a node

start:the starting point
end:the ending node
Returns:the newly created object.

Function: xmlXPtrLocationSetMerge

xmlLocationSetPtr	xmlXPtrLocationSetMerge	(xmlLocationSetPtr val1, 
				 xmlLocationSetPtr val2)

Merges two rangesets, all ranges from @val2 are added to @val1

val1:the first LocationSet
val2:the second LocationSet
Returns:val1 once extended or NULL in case of error.

Function: xmlXPtrEvalRangePredicate

void	xmlXPtrEvalRangePredicate	(xmlXPathParserContextPtr ctxt)

[8] Predicate ::= '[' PredicateExpr ']' [9] PredicateExpr ::= Expr Evaluate a predicate as in xmlXPathEvalPredicate() but for a Location Set instead of a node set

ctxt:the XPointer Parser context

Function: xmlXPtrLocationSetDel

void	xmlXPtrLocationSetDel	(xmlLocationSetPtr cur, 
				 xmlXPathObjectPtr val)

Removes an xmlXPathObjectPtr from an existing LocationSet

cur:the initial range set
val:an xmlXPathObjectPtr

Function: xmlXPtrNewRange

xmlXPathObjectPtr	xmlXPtrNewRange	(xmlNodePtr start, 
				 int startindex, 
				 xmlNodePtr end, 
				 int endindex)

Create a new xmlXPathObjectPtr of type range

start:the starting node
startindex:the start index
end:the ending point
endindex:the ending index
Returns:the newly created object.

Function: xmlXPtrFreeLocationSet

void	xmlXPtrFreeLocationSet	(xmlLocationSetPtr obj)

Free the LocationSet compound (not the actual ranges !).

obj:the xmlLocationSetPtr to free

Function: xmlXPtrWrapLocationSet

xmlXPathObjectPtr	xmlXPtrWrapLocationSet	(xmlLocationSetPtr val)

Wrap the LocationSet @val in a new xmlXPathObjectPtr

val:the LocationSet value
Returns:the newly created object.

Function: xmlXPtrNewRangeNodes

xmlXPathObjectPtr	xmlXPtrNewRangeNodes	(xmlNodePtr start, 
				 xmlNodePtr end)

Create a new xmlXPathObjectPtr of type range using 2 nodes

start:the starting node
end:the ending node
Returns:the newly created object.

Function: xmlXPtrLocationSetCreate

xmlLocationSetPtr	xmlXPtrLocationSetCreate	(xmlXPathObjectPtr val)

Create a new xmlLocationSetPtr of type double and of value @val

val:an initial xmlXPathObjectPtr, or NULL
Returns:the newly created object.

Function: xmlXPtrLocationSetAdd

void	xmlXPtrLocationSetAdd	(xmlLocationSetPtr cur, 
				 xmlXPathObjectPtr val)

add a new xmlXPathObjectPtr to an existing LocationSet If the location already exist in the set @val is freed.

cur:the initial range set
val:a new xmlXPathObjectPtr

Function: xmlXPtrRangeToFunction

void	xmlXPtrRangeToFunction	(xmlXPathParserContextPtr ctxt, 
				 int nargs)

Implement the range-to() XPointer function

ctxt:the XPointer Parser context
nargs:the number of args

Function: xmlXPtrNewLocationSetNodes

xmlXPathObjectPtr	xmlXPtrNewLocationSetNodes	(xmlNodePtr start, 
				 xmlNodePtr end)

start:the start NodePtr value
end:the end NodePtr value or NULL
Returns:the newly created object.

Function: xmlXPtrNewContext

xmlXPathContextPtr	xmlXPtrNewContext	(xmlDocPtr doc, 
				 xmlNodePtr here, 
				 xmlNodePtr origin)

Create a new XPointer context

doc:the XML document
here:the node that directly contains the XPointer being evaluated or NULL
origin:the element from which a user or program initiated traversal of the link, or NULL.
Returns:the xmlXPathContext just allocated.

Function: xmlXPtrNewRangeNodeObject

xmlXPathObjectPtr	xmlXPtrNewRangeNodeObject	(xmlNodePtr start,
