.NET Forum / Languages / C# / February 2008Relative XSD path
Hi guys, I want to validate my xml by xsd schema. But in the xsd file I have RELATIVE includes to the others xsd files that located in ..\ directory for the main xsd. Could you provide me code example that makes such a validation. All the examples I found in google doesn't work. Thanks a lot, Aleksey What environment? asp.net? standard exe? etc? If I recall, this should simply work (I'll run a quick test in a moment to check) - however, it isn't hard to roll a custom XmlResolver if you want to take control of where nested xsd come from; I use such to pull my xsd from a resource file, for example. Marc I work in winforms environment. I have main xsd that includes another in the next way: <xs:include schemaLocation="..\MessageHeader.xsd"/> Would you please send me your test code, that will resolve me the problem? Thanks a lot, Aleksey > What environment? asp.net? standard exe? etc? > [quoted text clipped - 4 lines] > > Marc Try swapping the slash; the following works fine for me: <xs:include schemaLocation="../Inner.xsd"/> Let me know how you get on; I have a working console exe that works fine with this approach, but I don't want to swamp you with xsd, xml and cs unless the above fails ;-p Marc No it doesn't help :( Still when I call reader = XmlReader.Create( new StringReader( xml ), settings ); it fails with the next exception: System.NullReferenceException: Object reference not set to an instance of an object Would you please provide me your test code, so I'll check what don't I do right? Thank you a lot for your help!!! Aleksey > Try swapping the slash; the following works fine for me: > [quoted text clipped - 5 lines] > > Marc I have (where there is also a Foo/Inner.xsd, included as per the previous post); my "Oops" handler just writes a message to the console to verify that my xml has been processed correctly (some valid, some invalid): XmlSchemaSet schema; using(XmlReader reader = XmlReader.Create("Foo/Bar/Outer.xsd")) { schema = new XmlSchemaSet(); schema.Add(XmlSchema.Read(reader, Oops)); schema.Compile(); } XmlReaderSettings settings = new XmlReaderSettings(); settings.Schemas = schema; settings.ValidationEventHandler += Oops; settings.ValidationType = ValidationType.Schema; using (XmlReader reader = XmlReader.Create("Sample.xml", settings)) { while (reader.Read()) { } } Marc Thanks a lot, Marc! It works now. The problem was the next: I had pretty the same code with one defferance that I used in StreamReader instead of XmlReader in the first "using" statement. Thank you a lot once again!

Interesting; I learn't something there (don't use StreamReader here ;-p) - so thanks for that. Cheers, Marc (for completeness, this is the XmlReader.BaseURI property; there is nothing equivalent for raw streams - plus you've gotta love the consistent casing [URI vs Uri] and return type [System.String vs System.Uri]) Marc Free MagazinesGet these publications absolutely FREE for up to 12 months.
