RE: conditional inlcudes -is it possible?

Hi,

You can't do it in XSL. But you can do it with a URIResolver in something like
java. You can pass the arguments you need to the object and determine which file
to include. For examplpe:

TransformerFactory factory = TransformerFactory.newInstance();
factory.setURIResolver(new MyResolver(some_argument));
...

class MyResolver implements URIResolver {
  String arg;

  public MyResolver(String _arg) {
    this.arg = _arg;
  }

  public Source resolve(String href,String base) {
    String file_str = "some starting path";
    if (href.equals("boo")
      file_str = file_str;
    } else if (href.equals("foo")) {
      file_str = file_str + this.arg;
        }
    File file = new File(file_str,href);
        if(file.exists()) return new StreamSource(file);
        return null;
  }
}

You set the resolver on the factory and then things like xsl:include/import and
document() are handled by 'MyResolver'

best,
