xslt transforms as a web service

If you can get by with xslt 1.0, xsltproc is much faster for rapid prototyping.

Saxon-HE is the only open source xslt 2.0 (and 3.0!) processor. As a cli app, the jre start time does it no favours. Instead, this repo runs Saxon-HE as a web service. On my machine, transform time was 3x better compared to the cli.

Run a transform with your favourite http client. Note the url query params, especially the cache busting:

http --print b ':8090?style=/app/mytransform.xslt&source=/app/mydoc.xml&clear-stylesheet-cache=yes' | tee output.txt

This was thrown together with great speed and only just enough care.

build and run the service

When you need to build the jar:

docker run --rm -v "$PWD:/app" -w /app maven:3.5.3-jdk-8-alpine mvn package

Once you have the jar:

docker build -t xsltservlet .
docker run --rm -p "8090:8080" -v "<MYWORKDIR>:/app" xsltservlet
