I am new to XML and have a business requirement that I think Infopath might
be the solution.  We are dealing with a large customer who would like us to
deliver monthly invoices in the cXML format.  The customer is under contract
so the invoice will change very little from month to month.  

My hope was that I could create an Infopath form that AR dept can open each
month and make the simple changes necessary and then possibly code a button
on the bottom of the form that will submit the xml file to the customers http
site.

Once thing I have noticed in testing is that the xml output seems to have
two InfoPath processing-instructions at the top.  Will I have to create some
code to remove these before the file is actually submitted, or is there some
sort of option within Infopath that will prevent them from being included in
the xml output?

Thanks for any help (and I need all I can get).
