Description
This implements the DOM Level 3 XPath W3C Working Draft 08 February 2002. API SUBJECT
TO CHANGE!
The evaluation of XPath expressions is provided by GdomeXPathEvaluator,
which will provide evaluation of XPath
1.0 expressions with no specialized extension functions or variables.
It is expected that the GdomeXPathEvaluator interface will be implemented
on the same object which implements the GdomeDocument interface in an
implementation which supports the XPath DOM module. GdomeXPathEvaluator
implementations may be available from other sources that may provide
support for new versions of XPath or special extension functions or
variables which are not defined in this specification.
Details
struct GdomeXPathEvaluator
struct GdomeXPathEvaluator {
gpointer user_data;

gdome_xpeval_mkref ()
Constructor of the XPathEvaluator interface.
gdome_xpeval_ref ()
Increase the reference count of the XPathEvaluator structure.
gdome_xpeval_unref ()
Decrease the reference count of the XPathEvaluator. Free the structure
if XPathEvaluator will have zero reference.
gdome_xpeval_createNSResolver ()
Adapts any DOM node to resolve namespaces so that an XPath expression
can be easily evaluated relative to the context of the node where it
appeared within the document.
gdome_xpeval_createResult ()
gdome_xpeval_evaluate ()
Evaluates an XPath expression string
