XPathContext.XPathExpressionContext
public XPathContext.XPathExpressionContext()
getXPathContext
public XPathContext getXPathContext()
- Return the XPathContext associated with this XPathExpressionContext.
Extensions should use this judiciously and only when special processing
requirements cannot be met another way. Consider requesting an enhancement
to the ExpressionContext interface to avoid having to call this method.
- Returns:
- the XPathContext associated with this XPathExpressionContext.
getDTMManager
public DTMManager getDTMManager()
- Return the DTMManager object. Though XPathContext context extends
the DTMManager, it really is a proxy for the real DTMManager. If a
caller needs to make a lot of calls to the DTMManager, it is faster
if it gets the real one from this function.
getContextNode
public org.w3c.dom.Node getContextNode()
- Get the current context node.
- Specified by:
- getContextNode in interface ExpressionContext
- Returns:
- The current context node.
getContextNodes
public org.w3c.dom.traversal.NodeIterator getContextNodes()
- Get the current context node list.
- Specified by:
- getContextNodes in interface ExpressionContext
- Returns:
- An iterator for the current context list, as
defined in XSLT.
toNumber
public double toNumber(org.w3c.dom.Node n)
- Get the value of a node as a number.
- Specified by:
- toNumber in interface ExpressionContext
- Parameters:
n

- value of n as a number.
toString
public java.lang.String toString(org.w3c.dom.Node n)
- Get the value of a node as a string.
- Specified by:
- toString in interface ExpressionContext
- Parameters:
n
- Node to be converted to a string. May be null.- Returns:
- value of n as a string, or an empty string if n is null.
getVariableOrParam
public final XObject getVariableOrParam(QName qname)
throws javax.xml.transform.TransformerException
- Get a variable based on it's qualified name.
