xalan_1_2_D01 crashes

[Claudio Sacerdoti Coen <sa...@students.cs.unibo.it>]

 Hi developers,

  I have just installed the 1_2_D01 versione of xalan and it crashes when
  the 1_1 version doesn't.

  The problem seems to me that you are using a wrong version of org.w3c.dom
   classes (or of xerces, perhaps).

  In src/org/apache/xalan/xpath/xdom/XercesLiason.java the code was:

=============
  /**
   * Get the parent of a node.
   */ 
  public Node getParentOfNode(Node node)
    throws RuntimeException
  {   
    return (Node.ATTRIBUTE_NODE == node.getNodeType())
           ? ((AttrImpl)node).getElement() : node.getParentNode();
  }
=============

  And now it is:

=============
  /**
   * Get the parent of a node.
   */
  public Node getParentOfNode(Node node)
    throws RuntimeException
  {
    return (Node.ATTRIBUTE_NODE == node.getNodeType())
           ? ((Attr)node).getOwnerElement() : node.getParentNode();
  }
=============

  but if I try to rebuild xalan I get this error:

=============
org/apache/xalan/xpath/xdom/XercesLiaison.java:396: Method getOwnerElement()
not found in interface org.w3c.dom.Attr.
           ? ((Attr)node).getOwnerElement() : node.getParentNode();
=============


  and in fact the dump of the exception stack is:

=======================
Exception in thread "main" java.lang.NoSuchMethodError: org.w3c.dom.Attr:
method getOwnerElement()Lorg/w3c/dom/Element; not found

=======================

 I don't think you need the stylesheet and the XML file to fix the
 problem.

						Good work,

 Please, ignore the previous message. I forgot I had also saxon in
 my CLASSPATH...
