      public XPathFilterParameterSpec(String xPath, Map<String,String> namespaceMap)
      Creates an XPathFilterParameterSpec with the specified XPath expression and namespace map. The map is copied to protect against subsequent modification.
      Parameters:
      xPath - the XPath expression to be evaluated
      namespaceMap - the map of namespace prefixes. Each key is a namespace prefix String that maps to a corresponding namespace URI String.
