Hugo, You always can do: - extract SVG - run your fragment-extractor-svg.xsl - extract JFC - run your fragment-extractor-jfc.xsl >The problem is created by the "FragmentExtractorTransformer.java" class. >It knows the name of the element it is filtering, but it does not pass it >any further. >So the easiest solution seems to be to add a new attribute that passes the >name of the filtered element.
