XML Help

[Vidya Sridhar]

I am a newbie with XML based interfaces.

I need help with converting XML file to HL7 for an inventory interface. The vendor had given me a XML data file (inv10.xml) with some of the data populated. I went ahead and generated a xsd schema for it. I have compiled the .xsd file in XML Package Manager and used it in my Xlate to convert to a HL7 message for the receiving side. This works well when the fields are populated to the point the .xsd was generated. When new fields in the XML document that were not populated during the .xsd generation are valued, the validation on Cloverleaf fails. Is there a way to make all the fields optional in XML? What is the best fix for this issue?

Thanks!

Ask – no demand – the vendor give you an XML schema for the XML message structure he is sending.

Why should you have to guess at his message structure?

XML does not forgive you.

If your DTD does not have fields defined in it that come to you. It will always fail.

The vendor should have a schema they have too. Make them send it to you.  

If they can’t or refuse. You wil always have to redefine you DTD to include the new fields and accpet sometimes the messages will fail.
