However, the Info Set that the Xml Validating Reader acts on is somehow now the same. Since Xml Validating Reader needs an Xml Text Reader that is more "legit," we'll give it one This is cheesy, but if a better way is found at least it's compartmentalized and I can fix it in one place.

We quickly run through the input Xml Text Reader, write the Infoset out to a Memory Stream and return a "fresh" Xml Text Reader and darn it if it doesn't work just fine.

Xml Document doc = new Xml Document(); Xml Validating Reader reader = new Xml Validating Reader(new Xml Text Reader(stream)); reader. The problem occurs when the incoming XML contains no DOCTYPE attribute. Load(reader); The XML document's stream is contained in the stream variable Here is My DTDResolver declaration: private class My DTDResolver: Xml Url Resolver The problem occurs when the incoming XML contains no DOCTYPE attribute.

The resolver code never gets called and the validation does not occur at all. Is that a bug and there is no way to enforce the DTD even if the icoming XML file does not specify the DTD file? The resolver code never gets called and the validation does not occur at all. Is that a bug and there is no way to enforce the DTD even if the icoming XML file does not specify the DTD file? You can add Doctype to a document using a variety of methods.

As far as using the XSLT code to insert the DOCTYPE, I couldn't use it because the XML files that I receive could be very large and I do not want to regenerate the whole file just to check for its validity.

As for creating a custom Xml Reader, I initially tried it but it is not that simple since in order to fake the DOCTYPE attribute one has to first determine that it is missing or invalid and then simulate it only in that case. Here is what I ended up doing: Because the Validating Reader does not throw any exceptions if DOCTYPE is missing I just check Xml Document.

The documents come in like this: Before I'd look hard at the schema I had assumed that I could load them with an Xml Namespace Upgrade Reader. NET 1.1 has carnal knowledge of Xml Text Reader and is probably making some assumptions about the underlying stream and doing some caching rather than taking my fake-out Xml Reader's word for it.

This is a derivation of Xml Text Reader that does nothing but lie about the Namespace of every element. I know that the Xml Root Namespace Upgrading Reader works because the XML is correct when it's written out to an intermediate.

This whole validation ickiness deserved two posts, so I didn't mention it in the last Xml Validating Reader post. But, the I remember/noticed that the document was element Form Default="unqualified" meaning that only the This document should now validate, and it fact it does in my test applications.

Visual Studio, when I open the file, validates it against the schema and lists errors perfectly.

Somehow, though, I can't seem to validate it automatically in C# without specifying the schema to validate against like so: Xml Document asset = new Xml Document(); Xml Text Reader schema Reader = new Xml Text Reader("relative Schema Path"); Xml Schema schema = Xml Schema.

It is a known shortcoming of the whole DTD approach that parsers do look for a DOCTYPE declaration to validate the XML against. NET classes to perform DTD validation but it might well be that you need to run your incoming XML stream through a filter mirroring all nodes but inserting the DOCTYPE declaration at the beginning to be able to perform the validation gainst the DTD.

  1. She and I posed for photos together as if we were boyfriend and girlfriend. But with full hindsight, there were so many warning signs. Of course, the walking tour conveniently ended at a luxurious restaurant. Later that afternoon, I received this text: I chalked up the whole experience to a life lesson and moved on.
