Usage

From source file:org.apache.xml.security.utils.CachedXPathFuncHereAPI.java

/**
 *   Evaluate XPath string to an XObject.
 *   XPath namespace prefixes are resolved from the namespaceNode.
 *   The implementation of this is a little slow, since it creates
 *   a number of objects each time it is called.  This could be optimized
 *   to keep the same objects around, but then thread-safety issues would arise.
 *
 *   @param contextNode The node to start searching from.
 *   @param xpathnode/*from w  w  w.  j a va  2  s  .c o m*/
 *   @param str
 *   @param prefixResolver Will be called if the parser encounters namespace
 *                         prefixes, to resolve the prefixes to URLs.
 *   @return An XObject, which can be used to obtain a string, number, nodelist, etc, 
 *   should never be null.
 *   @see org.apache.xpath.objects.XObject
 *   @see org.apache.xpath.objects.XNull
 *   @see org.apache.xpath.objects.XBoolean
