if DOM doesn't allow you to modify the tree, then why are there
"setAttribute" methods? and create...() methods??
one of the really really nice things (IMNSHO) about XPATH, is the ability to
select out a particular node and modify it without having to walk
through the entire tree!
this code works for me:
Document doc = . . .;
String PICTURE = "picture";
String NAME = "name";
String FILENAME = "foo.jpg";
.
.
.
// Create a <picture name="foo.jpg"> element & attribute
Element picture = doc.createElement( PICTURE );
Attr picname = doc.createAttribute( NAME );
picture.setAttributeNode( picname );
picture.setAttribute(NAME, FILENAME);
/** then go on to add child text nodes and append it to
* the appropriate node in the document.
* If you like, i can give you that code too...
