    • getPrefix

      protected static String getPrefix(NodePointer pointer, String namespaceURI)
      Find the namespace prefix for the specified namespace URI and NodePointer.
      Parameters:
      pointer - location
      namespaceURI - to check
      Returns:
      prefix if found
      Since:
      JXPath 1.3
    • registerNamespace

      public void registerNamespace(String prefix, String namespaceURI)
      Registers a namespace prefix.
      Parameters:
      prefix - A namespace prefix
      namespaceURI - A URI for that prefix
    • setNamespaceContextPointer

      public void setNamespaceContextPointer(NodePointer pointer)
      Register a namespace for the expression context.
      Parameters:
      pointer - the Pointer to set.
    • getNamespaceContextPointer

      Get the namespace context pointer.
      Returns:
      Pointer
    • getNamespaceURI

      public String getNamespaceURI(String prefix)
      Given a prefix, returns a registered namespace URI. If the requested prefix was not defined explicitly using the registerNamespace method, JXPathContext will then check the context node to see if the prefix is defined there. See setNamespaceContextPointer.
      Parameters:
      prefix - The namespace prefix to look up
      Returns:
      namespace URI or null if the prefix is undefined.
    • getExternallyRegisteredNamespaceURI

      Given a prefix, returns an externally registered namespace URI.
      Parameters:
      prefix - The namespace prefix to look up
      Returns:
      namespace URI or null if the prefix is undefined.
      Since:
      JXPath 1.3
    • getPrefix

      public String getPrefix(String namespaceURI)
      Get the prefix associated with the specifed namespace URI.
      Parameters:
      namespaceURI - the ns URI to check.
      Returns:
      String prefix
    • getExternallyRegisteredPrefix

      protected String getExternallyRegisteredPrefix(String namespaceURI)
      Get the nearest prefix found that matches an externally-registered namespace.
      Parameters:
      namespaceURI - the ns URI to check.
      Returns:
      String prefix if found.

      JXPath 1.3
