p2p.wrox.com, look up code for Professional VB.NET Chapter 10--on XML--maybe
something there can help you. If not try
www.superexpert.com, "ASP
Unleashed" Look at code for Chapter 13.
Both of these deal with XML and are really the extent of what I know but
just haven't used it much.
You can easily iterate through your form posted elements as I have said
before. If all have a unique name, then you can get "NameofElement" and
then go get it's value as mentioned before... Do that in a loop using the
count-1 property of the collection.
Inside of that as to what to do with it in XML, John is write--that is an
XML question better directed at an XML group. But maybe the sample code
from one of the books I mentioned might have something you need.
Sorry I can't be of further help.
