You could do the exact same thing using XSLT. eg.

    var result = new XSLTProcessor().importStylesheet(xsl).transform(....);

It's a bit of a pointless example because it really depends on the transformations you need. I'm sure in some cases XSLT would be better for the job, and in other cases another language. Most of the time it would generally just depend on your environment, available tools and skillset.
