> When you clone a Node using cloneNode(true) and later invoke
> getElementsByTagNameNS a class cast exception is thrown in getElementNS.
> The reason for this is that getElementNS casts to Element if the object under
> inspection is not an instance of Text. However, org.apache.axis.message.Text
> does not override NodeImpl.cloneNode(boolean deep). Thus, when I cloned my
> Node all Text nodes got replaced by NodeImpl nodes as the NodeImpl.cloneNode
> method was called (and this method returns instances of type NodeImpl).
> Thus my clone contained nodes which were neither of type Element nore of type
> Text but of type NodeImpl. Thus the class cast exception in getElementNS
> (which assumes a node is of type Element if it's not of type Text).
> I suggest so resolve this issue by implementing cloneNode in Text in a
> similar fashion it is implemented in NodeImpl:
> /**
> * Returns a duplicate of this node, i.e., serves as a generic copy
> * constructor for nodes. The duplicate node has no parent; (
> * <code>parentNode</code> is <code>null</code>.).
> * <br>Cloning an <code>Element</code> copies all attributes and their
> * values, including those generated by the XML processor to represent
> * defaulted attributes, but this method does not copy any text it
> * contains unless it is a deep clone, since the text is contained in a
> * child <code>Text</code> node. Cloning an <code>Attribute</code>
> * directly, as opposed to be cloned as part of an <code>Element</code>
> * cloning operation, returns a specified attribute (
> * <code>specified</code> is <code>true</code>). Cloning any other type
> * of node simply returns a copy of this node.
> * <br>Note that cloning an immutable subtree results in a mutable copy,
> * but the children of an <code>EntityReference</code> clone are readonly
> * . In addition, clones of unspecified <code>Attr</code> nodes are
> * specified. And, cloning <code>Document</code>,
> * <code>DocumentType</code>, <code>Entity</code>, and
> * <code>Notation</code> nodes is implementation dependent.
> *
> * @param deep If <code>true</code>, recursively clone the subtree under
> * the specified node; if <code>false</code>, clone only the
> node
> * itself (and its attributes, if it is an
> <code>Element</code>).
> * @return The duplicate node.
