No problem,
I am generally surprised it is not a more generally proposed solution (most
likely because it is java based -- JAXP). It is pretty simple.
There is a very simple way to implement it. I will point you to read:
http://xml.apache.org/commons/components/resolver/index.html
There are more complex ways that some of us need, but this should suffice.
But basically (in a simplistic way) all you need to do is pass some kind of
Map (key=value, or in other words href=resolvable_custom_uri) or an object
that holds the Map to the resolver. So this:
tFactory.setURIResolver(new MyResolver(""));
could be:
tFactory.setURIResolver(new MyResolver(myProject));
and the URIResolver can look like:
public class MyResolver implements URIResolver
{
private Project project;
public MyResolver ( Project _project )
{
this.project = _project;
}
public Source resolve( String href, String base )
{
Source source = null;
try {
source = new StreamSource( this.project.someLookup( href ).getURL() );
}
catch ( Exception e ) {
...
}
if ( null == source )
source = new StreamSource( new StringReader( "<error/>" ) );
return source;
}
}

Thanks for your suggestion. As I understand it, the "arg:" is
a sort of custom uri. Still, it is not clear what it should
be resolving to.
Any advice on how to do the custom uri resolver, or how to
remove these "arg:" custom uris?

P.S. so far, it's like this:
TransformerFactory tFactory =
TransformerFactory.newInstance();
Source stylesheet = new StreamSource(xsl_file);
tFactory.setURIResolver(new MyResolver("")); //confusing bit
Transformer transformer = tFactory.newTransformer(stylesheet);
StreamSource strs= new StreamSource(xml_file);
StreamResult strr=new StreamResult(new FileOutputStream(out_file));
transformer.transform(strs, strr);

Hi,
You need to set up a custom javax.xml.transform.URIResolver (assuming
you
are using java). You will be passed two arguments when the resolve
method is
automatically called when you use document(href [, base]). The first one
is
the string you can use to resolve your custom URI.

Hi List,
I hope that this is an appropriate question for this list.
In trying to process an RDF foaf document [1] using the
stylesheet [2], the processor, which is members of the
javax.xml.transform package, gives an error which tells me that
the protocol "arg" is unknown in this statement:
<xsl:when test="document('arg:/ifp')/*/*/*">
<xsl:variable name="ifp">
<xsl:copy-of select="document('arg:/ifp')/*[1]/*[1]/*[1]"/>
</xsl:variable>
<xsl:apply-templates mode="output" ... />
</xsl:when>
or
<xsl:variable name="def"
select="document('arg:/schema')/ns/schema[(_at_)ns=$ns]/rdf:RDF/*[(_at_)rdf:about=$t
his or @rdf:ID=$name or @ID=$name]"/>
and in several other places.
In looking over the documentation on document(), there is no
mention of a protocol "arg" or what this could possibly be. It
seems that the stylesheet is trying to refer to one of the
namespace URIs.

Thanks in advance for helping an XSL noob.
