RE: [docbook-apps] Use of XML Catalog with Ant (xslt task)

"If I'm understanding the original post correctly, you want to use catalogs so that ANT will resolve the location of the stylesheet specified in ant's <xslt/> task from the catalog"

That's correct.

"I don't know if ant can do that" "I only ever used ant+catalog files to resolve dtds and stylesheet locations specified in xsl:imports"

Interesting point.

The Ant docs say "This task supports the use of a nested xmlcatalog element which is used to perform Entity and URI resolution", which does not seem to explicitly include or exclude the use of the catalog to find the style file.

In Saxon I do a mixture. The initial (ie customization) stylesheets are looked-up using a catalog, then the standard stylesheets are xsl:import'ed again via a catalog lookup. Within those the file locations are relative paths.

My catalog has two <group> elements. One is for the locations of the customization stylesheets; the other is for the standard stylesheets.

I'm seeking to do this as it's what my existing Saxon-based transformations do, so I assumed Ant would be able to do so too. I have asked on the Ant mailing-list, and have just received a reply indicating that I may need to start delving into the Java code to sort out exactly what's going on. As a C++ programmer Java looks quite familiar, but I have no experience of actually working on it.

Uncertainly,

Richard.

If I'm understanding the original post correctly, you want to use
catalogs so that ANT will resolve the location of the stylesheet
specified in ant's <xslt/> task from the catalog. I don't know if ant
can do that, though I've never tried. I only ever used ant+catalog files
to resolve dtds and stylesheet locations specified in xsl:imports. It'd
be worth asking on an ant list or looking at the code for the xslt task
to see if it even supports that.

If you ever do get it working, be sure to let us know. It would be a
convenient thing to have.

David
