nsPrefix
- the namespace prefixnsURI
- the namespace URI to associate
-
generateId
Creates a unique identifier for the given node- Returns:
- the String that is a unique identifier for the given node
-
getCurrentNode
Returns the "current" node The current node, is different than the context node, as the context node may change during the evaluation of an xpath expression, the current node does not. Basically it's the first context node during the beginning of an xpath evalation.- Returns:
- the "current" node
- See Also:
-
getErrorObserver
Returns the ErrorObserver to report errors to- Returns:
- the ErrorObserver to report errors to
-
getStylesheetLocation
-
getParameter
Returns the parameter value associated with the given name.- Parameters:
name
- the name of the parameter to retrieve the value of- Returns:
- the parameter value associated with the given name.
-
getProperty
Returns the Property value associated with the given name. All property names without a namespace are defaulted to the System evironment scope.- Parameters:
name
- the name of the property to get the value of- Returns:
- the Property value associated with the given name.
-
getXMLSpaceModes
Returns the stack of XML space modes -
getNamespaceURI
Returns the namespace associated with the given prefix. A namespace can be associated with a given prefix via the XSLT document being processed, or using #associateNamespace method- Overrides:
getNamespaceURI
in classXPathContext
- Parameters:
prefix
- the prefix of the namespace to return- Returns:
- the namespace prefix or null if none found.
-
getURIResolver
Returns the URIResolver for resolving all URIs.- Returns:
- the URIResolver for resolving all URIs.
-
isFunctionAvailable
Returns true if a function with the given name exists within the given namespace.- Returns:
- true if a function with the given name exists
-
isXSLTNamespace
Determines if the given prefix or URI maps to the XSLT namespace- Parameters:
prefixOrURI
- the prefix or URI to compare with the XSLT namespace- Returns:
- true if the given prefix or URI maps to the XSLT namespace
-
popHandler
Removes and returns the ResultHandler from the top of the ResultHandler stack.- Returns:
- the ResultHandler that was at the top of the stack.
-
pushHandler
Pushes a new ResultHandler to the top of the ResultHandler stack.- Parameters:
handler
- the ResultHandler to push to the top of the stack.
-
popCurrentNode
Removes the current node from the top of the stack The current node, is different than the context node, as the context node may change during the evaluation of an xpath expression, the current node does not. Basically it's the first context node during the beginning of an xpath evalation.- Returns:
- the current node.
- See Also:
-
pushCurrentNode
Adds the given node to the top of the "current" node Stack. The current node, is different than the context node, as the context node may change during the evaluation of an xpath expression, the current node does not. Basically it's the first context node during the beginning of an xpath evalation.- Parameters:
node
- the new current node- See Also:
-
pushNodeSet
