I have a relaxng schema embedded in a dll as a resource. The relaxng schema
includes other schemas, and those schemas include other schemas as well. All
the schemas are inside the dll. I use a custom XmlUrlLoader to load the
dependencies from inside my dll. However, it seems like the
RelaxngPAttern.Compile sometime calls my custom XmlUrlLoader, but also sometime
doesn't!
Here is the code I use:
----------------Code to load and compile the relaxngSchema
CMSD_RELAXNG_SCHEMA = "CMSD_V1.0.rng";
RelaxngPattern p = null;
XmlUrlResolver resolver = new EmbeddedResourceResolver(GetType());
using(XmlTextReader schema = new
XmlTextReader(Assembly.GetExecutingAssembly().Location,Assembly.GetExecutingAssembly().GetManifestResourceStream(this.GetType(),CMSD_RELAXNG_SCHEMA)))
{
Console.WriteLine("---- Reading Schema ----");
p = RelaxngPattern.Read(schema,null,resolver);
p.XmlResolver = resolver;
Console.WriteLine("---- Compiling Schema ----");
p.Compile();
}
-------------My custom XmlUrlLoader
public class EmbeddedResourceResolver: XmlUrlResolver
{
private Type type;
private Assembly assembly;
public EmbeddedResourceResolver(Type t)
{
type = t;
assembly = t.Assembly;
}
public override object GetEntity(Uri absoluteUri, string role, Type
ofObjectToReturn)
{
Console.WriteLine(" Getting Entity absoluteUri:{0}, role:{1},
type: {2}", absoluteUri,role,ofObjectToReturn.ToString());
String fullPath = absoluteUri.AbsolutePath;
String name = Path.GetFileName(fullPath);
//return
assembly.GetManifestResourceStream(this.GetType(),name);
return assembly.GetManifestResourceStream(this.GetType(),
absoluteUri.Segments[absoluteUri.Segments.Length - 1]);
}
public override Uri ResolveUri(Uri baseUri, string relativeUri)
{
Console.WriteLine(" Resolving Uri with baseUri: {0},
relativeUri: {1}", baseUri, relativeUri);
if(baseUri == null)
{
baseUri = new Uri(assembly.Location);
}
Uri res = base.ResolveUri(baseUri, relativeUri);
Console.WriteLine(" ->Resolved to {0}", res);
return res;
}
}
---------------------Here is the output on the console (I shortened the urls
for clarity)

-----------------------------
What surprises me is that in the inner exception, you can see that
System.Xml.XmlUrlResolver.GetEntity(...) is being called, even though I
provided my own xmlUrlResolver.
The relaxng schema used can be found here:
