[Dojo-interest] dojo.xml.XlsTransform feature request

[Joerg-D Schneider]

Hi Rob,

I don't think so - we have around 12-15 applications using hundreds of 
different xml documents / stylesheets following this approach and did not 
run into problems for the last 4 years. Since we anyway create most of the 
xml documents dynamically on the server, we usually assign the correct 
stylesheet on the server.

I don't think that there is a need to instantiate the XslTransform object. 
To be honest, not having to instantiate the XslTransform would be a 
benefit if you just want to transform a xml containing information about 
what stylesheet to use.
The way the current implementation works, I need to know the stylesheet 
URL before I can instantiate the XslTransform object and afterwards I call 
one of its transform method passing in the xml to be transformed. I'd 
think it would be handy, to directly call one of the transformation 
methods just giving an xml and I'm done. Anyhow, I understood that 
apparently we do not share the same opinion about that :-)
I don't get your point regarding the simple parsing of an XML instance 
would trigger a transformation - if I load an xml document via javascript 
that contains a xsl stylehsheet PI nothing will happen - what is your 
expectation in this respect ? If it would be automatically transformed by 
the browser, what is the dojo.xml.XslTransform package purpose then ? If 
you want to have it transformed within your javascript you will need to 
initiate a xsl transformation yourself. This is different if such an xml 
is loaded by the browser (not by javascript means) - then the xml is 
transformed automatically using the implied stylesheet.


Mit freundlichen Grüßen / Kind regards
