Glad to hear that it has been a help.
Please send me a description of the source that you wrote (or
the source itself) that is giving you trouble ... hard to tell exactly what it
is without seeing it ... I have an idea ... maybe ... we'll see :)

Subject: Re: Domprint and overwriting
files
Hi,
Thanks a million for your help I have taken your
suggestions.
At the moment I am opening a file inserting new data and
saving the new file; the only trouble is that the information between the tags
is being saved but the tags aren’t.
I.e. I open and parse a file with a structure similar to
this:
<Exception_Event>
<ID>0</ID>
<message>feeder not
found</message>
</Exception_Event>
but my new saved file has a structure like this:
0
feeder not found
Can you help?
Thanks,
Emma
