Hi,

I'm new at c#.  I have a web service that is being called from Oracle's BPEL process.  I need to read the xml and parse the values in the elements.  The XML will purchase order header information and lines.  I need to capture the values for the header and strings these values and then I call an existing Webservice.  When I return I need to check the if its a good transaction.  If so then I want to continue and the value for the lines.  If a bad return from the header then I want to return back to Oracles BPEL with the error message in a XML document format.  Now there can be mulitple lines as well.  I would do the same process for the lines as I did for the header.  Here is an example or the XML:
