[xml-dev] using alternative stylesheet in an xml

[priya <priyag@newgen.co.in>]

Hi all!
i m facing a problem while developing the xml. I have an xml which has a
hardcoded path of stylesheet which is a xsl file. Now i want to generate an
xml file which has references of two stylesheets in a way that if one of the
stylesheet is not available then it will take another stylesheet to display
the file. I don't know how to do this... can anyone help me to do this.
thanx
