end: | the ending node |
Returns : | the newly created object. |
xmlXPathObjectPtr xmlXPtrNewLocationSetNodes (xmlNodePtr start, xmlNodePtr end);
Create a new xmlXPathObjectPtr of type LocationSet and initialize it with the single range made of the two nodes start and end
start: | the start NodePtr value |
end: | the end NodePtr value or NULL |
Returns : | the newly created object. |
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. |
xmlXPathObjectPtr xmlXPtrNewRangeNodeObject (xmlNodePtr start, xmlXPathObjectPtr end);

start: | the starting and ending node |
Returns : | the newly created object. |
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 |
xmlXPathObjectPtr xmlXPtrWrapLocationSet (xmlLocationSetPtr val);

val: | the LocationSet value |
Returns : | the newly created object. |
void xmlXPtrLocationSetDel (xmlLocationSetPtr cur, xmlXPathObjectPtr val);
Removes an xmlXPathObjectPtr from an existing LocationSet
cur: | the initial range set |
val: | an xmlXPathObjectPtr |
void xmlXPtrLocationSetRemove (xmlLocationSetPtr cur, int val);
Removes an entry from an existing LocationSet list.
cur: | the initial range set |
val: | the index to remove |
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. |
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. |
void xmlXPtrRangeToFunction (xmlXPathParserContextPtr ctxt, int nargs);
Implement the range-
ctxt: | the XPointer Parser context |
nargs: | the number of args |
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. |
void xmlXPtrEvalRangePredicate (xmlXPathParserContextPtr ctxt);
[8] Predicate ::= '[' PredicateExpr ']' [9] PredicateExpr ::= Expr
