Hi Jason

It might be that

<?xml version="1.0" encoding="utf-8"?>
<WireTransfers xmlns="dsTransaction">
     <WireTransfer>
          <Value_Date>2007-02-15</Value_Date>
          <Amount>22222.33</Amount>
          <Bank_Action>R</Bank_Action>
          <Date_Blocked_Rejected>2007-02-15</Date_Blocked_Rejected>
          <Wire_Transfer_Transaction_Type>Bank to
Bank</Wire_Transfer_Transaction_Type>
           <other elements>
     </WireTransfer>
</WireTransfers>

will work - just need that xmlns="dsTransaction" at the top (maybe
add the schemaLocation too - example needs some correcting here)

can't say for sure without seeing the schema though but some of the
namespaces seem to be for the datatypes which probably don't need
to be included in the xml files

you'd probably want to tidy up the schema a fair bit too - looks like it
was generated and maybe not optimally for your purposes

All the best

I've done a lot of reading lately about XML as I've never really had
to work with it, but I've been tasked with developing an XML upload
for the business I support. I'm really surprised at the complexities.

Currently, I have the XML upload completed and it's working with the
various test files that I've created. I developed an XML schema and I
load the test file into a dataset once it passes validation.

There are a couple of things that I don't like about it though, and
I'm wondering if I can make this process better.

For one, I'm not happy with the fact that the xml file needs so much
information regarding namespaces.

This is what the top section of my XML file looks like:

<?xml version="1.0" encoding="utf-8"?>
<n:Transactions
xmlns:n="dsTransaction"
xmlns:mstns="http://tempuri.org/dsTransaction.xsd";
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
xmlns:codegen="urn:schemas-microsoft-com:xml-msprop"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance";
xs:schemaLocation="dsTransaction.xsd">

I don't see why the customers should have to include this stuff in their files.
They would need all those lines and then prefix all of their elements as below.
A single transaction sample is as follows:

<n:WireTransfers>
     <n:WireTransfer>
          <n:Value_Date>2007-02-15</n:Value_Date>
          <n:Amount>22222.33</n:Amount>
          <n:Bank_Action>R</n:Bank_Action>
          <n:Date_Blocked_Rejected>2007-02-15</n:Date_Blocked_Rejected>
          <n:Wire_Transfer_Transaction_Type>Bank to
Bank</n:Wire_Transfer_Transaction_Type>
           <other elements>
     </n:WireTransfer>
<n:/WireTransfers>

It seems to me that when the file is uploaded, I should be able to
validate the file against any schema I like. Does this sound right?
Could I take an XML file that looks like this:

<?xml version="1.0" encoding="utf-8"?>
<WireTransfers>
     <WireTransfer>
          <Value_Date>2007-02-15</Value_Date>
          <Amount>22222.33</Amount>
          <Bank_Action>R</Bank_Action>
          <Date_Blocked_Rejected>2007-02-15</Date_Blocked_Rejected>
          <Wire_Transfer_Transaction_Type>Bank to
Bank</Wire_Transfer_Transaction_Type>
           <other elements>
     </WireTransfer>
</WireTransfers>

And then validate it against my schema? I haven't been able to get a
sample file like that to work, so perhaps I'm wrong, but it seems like
a lot to require of the customers.

Thanks for any advice,
--Jason
