Re: [xsl] Indent?

Accoding to the XSLT spec, indent is considered a hint to the serializer, and the exact results are not specified. There are rules saying where you can't introduce whitespace, but no requirement that you do so in all the places it's allowed, nor how much. Implementation dependent. Xalan *does* support indentation... but our default indentation-per-level is 0; we generate only the line-breaks. To get actual structural indentation, you need to say how much you want, using a Xalan-specific directive; see http://xml.apache.org/xalan-j/usagepatterns.html#outputprops Yes, this is nonportable (though it's harmless to other processors) -- but as I said above, indent's behavior is nonportable. If you want predictable whitespace, your stylesheet has to generate that itself, using xsl:text directives. That's just the nature of the beast, I'm afraid. (We can argue -- and have argued many times! -- about whether 0 is the right default for per-level indentation. I've become completely agnostic on that issue, since no matter what value you pick someone always screams.) ______________________________________ Joe Kesselman, IBM Next-Generation Web Technologies: XML, XSL and more.
