Re: [xsl] Running the same transformation on many input files, optimisation possible?

You may have a look at gaulois-pipe, which is design to cache XSL compile results, to run multi-files transformation in parallel, and other simple things made to go fast.

https://github.com/cmarchand/gaulois-pipe/wiki

We use it a lot, as it allows, through a pipeline definition file, to run various XSL pipelines, without writing anymore java code or shell code.

Best,
Christophe

Hi

An application I am working on contains a large number of source documents which are all run through the same series of transformations. While initially the build process didn't take long the cost of repeatedly initialising the XSL processor soon adds up, so I am looking at ways to streamline it.

Our processor of choice is Saxon (currently we are using 8.7.3) so I can shift this question to the Saxon list if there are extensions there that are relevant.

So the question; given a script that essentially includes the following:

cd documents

for d in `cat dlist`; do

  cd $d

  for f in `cat flist`; do

    java -jar $SAXONDIR/saxon8.jar  -o  $f.new.xml  $f.xml  $SCRIPTDIR/transform.xsl  doc=$d  file=$f

  done

done

is there a mechanism which would allow a single Java process to perform the equivalent?

Thanks
