Greetings to all -

I'm having a problem processing xml with relative dtd URI specified
using XSLT:

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mydoc SYSTEM "my.dtd">
<mydoc>
...
</mydoc>

I do not have a control over the original xml but I have my.dtd in the
app classpath. I'm getting the TransformerException: Relative URI
"my.dtd" can not be resolved without a base URI.

How do I tell to javax.xml.transform.Transformer where to find the dtd
file w/out specifying the base URI (or any other modifications of the
original xml)?

Here is how I call the xsl transformer:

//  1. Instantiate a TransformerFactory.
javax.xml.transform.TransformerFactory tFactory =
	javax.xml.transform.TransformerFactory.newInstance();

//  2. Use the TransformerFactory to process the stylesheet Source and
//     generate a Transformer.
javax.xml.transform.Transformer transformer =
	tFactory.newTransformer(new
javax.xml.transform.stream.StreamSource(xsl));

//transformer.setURIResolver(new RelativeURIResolver());

//  3. Use the Transformer to transform an XML Source and send the
//     output to a Result object.
transformer.transform(
	new javax.xml.transform.stream.StreamSource(xml),
	new javax.xml.transform.stream.StreamResult(out));

As you can see above, I've tried to use URIResolver() but it does not
appear to be used by the transformer to resolve the DTD.

I'm using Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.2_03-b02) and default xslt processor and xml parser from there
("org.apache.xalan.processor.TransformerFactoryImpl" and
"org.apache.crimson.jaxp.DocumentBuilderFactoryImpl" I assume).

Of course, I could use java.util.regex to either remove
<!DOCTYPE[a-zA-Z0-9\". ]*> completely or to add the base url there.
But I wonder if there is more elegant solution to this.

Any suggestions are very appreciated.
Thanks
Pavel
