Write Xml()" and later prompt my users for the name of the filein order to read it back in again (using "Data Set. I'm still looking into it but I'm fairly new to XML and so it's a learning process. I was going to respond to your first post in fact but was working on resolving the issue which I just did moments ago (with the help of an XML MVP elsewhere though I'm still testing things). Report Validation Warnings " in "Xml Reader Settings" and then Arne's example works (well, I changed it slightly). I've distributed schemas with application code before now as a plain file, although this was to a well constrained user population. Xml Exception" if they enter anon-XML file, a valid XML file results in no exception even though theschema may be completely incorrect (if they enter some random XML file onthe system that is). Try something like: Data Set ds = new Data Set("Test DS"); Xml Reader Settings xrs = new Xml Reader Settings(); xrs. Note however that "ds" from your example will actually be the wizard-generated "Data Set" derivative whose constructor creates all tables, etc. I don't like having to send my ".xsd" file out just for validation however (it's an internal detail) but I'm hoping it can be avoided somehow. I can't seem to resolve the issue any other way however.
Write Xml()" and later prompt my users for the name of the file in order to read it back in again (using "Data Set. If your worried about people tampering with it, you could store it in a file in your application. I originally thought it would be reported as an error but apparently not. In any case, my overall experience with this situation has been very frustrating. Load(@"C:\Temp\Test.xml"); // Open XML Definition and store for validation Xml Schema Set schemas = new Xml Schema Set(); schemas. Create(@"C:\Temp\Release XMLSchema.xsd")); bool errors = false; xml File. Validate(schemas, (o, e) = There must be some problem in the code that u are using to validate it..Validate(schemas, (o, e) = But every time I run the code I am told that "XMLDOC validated". Shouldn't my weird XML file cause validation to fail? coz when i validated ur xml againt xsd.gave me error as file:///c:/Documents and Settings/kavita/Desktop/test/why Validate.xml:3,233: Unknown element 'Release' file:///c:/Documents and Settings/kavita/Desktop/test/why Validate.xml:3,233: Attribute 'BLAHLBAH' is not declared for element 'Release' Also the Ok i see..u havent added the Validation handler.. I'll have to research it further but I'm basically doing this: 1) Create a strongly-typed (wizard-generated) dataset using VS (wizard-generated constructor creates all tables, constraints, etc.) 2) Populate it with data and write to file using "Data Set. 3) Read it back in using your code above, passing the wizard-generated ".xsd" file from step 1. If I now pass in an arbitrary (invalid) ".xml" file in step 3, the handler is never called. X that's now obsolete) so I'm probably safer relying on it. Read()) ; The XML is compliant, but it's still reporting an error: Could not find schema information for the element 'details'. That may not be true however so I may actually reject a conforming ".xml" file which will be a problem. Note that my experience with XML is very limited so I'm not sure what's wrong (I'm a very experienced developer however). Note that my ".xml" file actually uses another extension but I assume that's not an issue. I think Arne's way is really the "official" way in 2.0 anyway (there was another technique in 1. My testing shows that a conforming ".xml" file generates no warnings however so I'll have to assume that any warning is really an error and treat it that way. Xml Exception" if they enter a non-XML file, a valid XML file results in no exception even though the schema may be completely incorrect (if they enter some random XML file on the system that is). Hi Check out the Write Xml Schema, Read Xml Schema and Write Xml and Read Xml overloads of the Data Set type.

I promise you, this version works, honest ;-) class Program I haven't checked all of this thread, so apologies if I've missed the intended point. -- ============================================= Pete Cordell Tech-Know-Ware Ltd for XML to C data binding visit (or ============================================= I was so focused on finding out what was wrong with the code that I neglected to consider something was wrong with the schema.

And it's there for the purpose of making your application inputs more robust. Read() ); Doing so will cause the reader to walk over the document and pick up any problems.
The only reason I am not using the Xml Validating Reader is that it is deprecated in ASP. My code is identical to the Microsoft sample code demonstrated here: the Microsoft code works as expected in their own example, but fails to work for mine.
If I replace the Microsoft example xsd Markup with my own: It fails to detect any errors. This may be XML fundamentals, so apologies if it seems obvious, but it seems I was not specifying the correct namespace in the XML document after all.
You can also use a DTD to verify your own data." On 2007-01-12 -0600, Fo**********@said: validate that the file they enter is valid. To validate an ".xml" file, do you normally install its ".xsd" file for this purpose, assuming you don't need it for anything else.
Here's what to say about it: "Your application can use a standard DTD to verify that the data you receive from the outside world is valid. I'm not sure what the accepted protocol is however .
In that case you would then get warnings reported to your Validation Event Handler that there are elements for which not matching schema is found.
