How to remove tags and the removen tags'
content ?

Then save the result to the file?  @@.
By using the NodeVisitor pattern,followings is my codes.
The ^^^^ area is my focus.
Could someone good give me the hand? @@.

thank you
May god bless you all

You should be able to collect all the nodes you want to remove in a NodeList:

NodeList list = new NodeList (); // top level nodes gathered
NodeIterator iterator = parser.elements ();
while (iterator.hasMoreNodes ())
    list.add (iteartor.NextNode ());

And after completion of the visiting:
for (int i = 0; i < list.size (); i++)
    list.elementAt (i).accept (myvisitor);

Run through the list and do something like:
NodeList matching_ones = myvisitor.getMatchingNodes ();
for (int i = 0; i < list.size (); i++)
    item = matching_ones.elementAt (i);
...
list = item.getParent ().getChildren ();
for (int i = 0; i < list.size (); i++)
    if (item == list.elementAt (i))
    {
        list.remove (i);
        break;
     }
}

Then print the list of all nodes in a similar manner:
for (int i = 0; i < list.size (); i++)
    System.out.print (list.elementAt (i).toHtml ());

Follwings is my codes.
It work successfully to move the ScriptTag and it's content.
But my codes cannot move the word "Script" is in 'a' tag.
