& XSLT Excellent thanks! Ok so if I use removeChild how can I commit my changes
to the same file I was reading from? I know I can do something like
write to a new file all the items I finished. But I would rather not
have to do a check for each item in my current list to a item in the new
list. But if I HAVE to I will but just prefer to keep things as simple
and as clean as possible.
Thanks

it's removeChild, but that is only going to affect the
_in_memory_ tree; it isn't going to help recover
from crashes unless you serialize & write the dom
back to a file after each removal.

Not completely clear what you mean;
You certainly can replace the node by a node that isn't allowed
by the dtd/schema, so it can easily be non valid in that sense.
