How to create an XSD schema file from an XML file?

Question

I am trying to create an XSD schema file from an existing XML file but am getting errors. Currently I am trying to use the XSD command prompt tool to generate the XSD file. Any advice on mistakes with my XML file? Or any other tools I should try instead? Here is my XML file:

<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'

Answer 1

That looks like a document defined by NOTE-XML-Data, an W3C Note (not a Rec), rather than an XML Schema Document. Does your tool have options for the type of document output?

Answer 2

A very simple way to accomplish this would be to download the 30 day trial of Altova XML Spy. It has a very nice XML to XSD feature that you can customize completely.

Answer 3

It is my understanding that an XSDL schema document can only describe one namespace. Your XML document makes use of multiple namespaces, so you need to have a XSD file for each namespace (i.e. dt.xsd, rs.xsd z.xsd etc.)

Not familiar with SSIS, but I would assume that if it supports multiple XML namespaces and can validate each namespace against a schema, that it should support an XSD per namespace.
