Subject Re: xslt/transformer question
Date Thu, 16 Oct 2003 07:23:29 GMT
Hi Geert,
I have written a basic xml editor in cocoon that can result in large 
files in region of 150 to 200kb +. Obviously at the upper end of the 
file size it gets a bit sluggish but works none the less.
I use the source writing transformer to output the xml file to disk. 
Prior to this step, I wrap the required <source:write> tags around the 
document in a stylesheet which is basically an identity transform of the 
Hope this helps.
