XOM API for Processing XML with Java

["Grzegorz Kaczor" <grzegorz.kaczor AT gmail.com>]

Hello,

I think that there is no way to avoid scanning a whole file because
the <service> element can occur anywhere (yes, I know that it cannot
appear anywhere but XOM does not know that :) ). And I do not think
that there are more intelligent ways of modifying XML than read it and
write it back :(.

I think you can replace the node with the following code:
                Element el = new Element("synonym");
                el.addAttribute(new Attribute("name","ABCDE"));             
                node.getParent().replaceChild(node, el);

However, I can imagine a simpler way of doing that, without xpath -
XOM allows you to replace the NodeFactory, then when you handle
finishMakingElement you can filter out the elements you wish and
return your element instead of the <service> element. This will for
sure be quicker than xpath. See XOM tutorial page 23.

Hope this helps,
Grzegorz
