Re: [xsl] How to recover/continue from XML Transformation exception?

[Jack Bush <netbeansfan@xxxxxxxxxxxx>]

Hi Michael,
 
Apologies for having taking a while to respond due to other
commitments.
I have taken on board 2 (first & last) while staying with Saxon
9.1 and they 
appear to be working after some preliminary testing on limited
set of data.
 
Much appreciated for your advice again,
Jack

It's not entirely clear from your question, but if you are calling
transformer.transform() once for each XML file to be processed, you can catch
the Java exception and continue.

for(Source source : sources) {
  try {
     
transformer.transform(source);
  } catch (TransformerException err) {
     
System.err.println("This one failed");
  }
}

On the other hand, if you are
calling transform() once to process all the XML 
files, you will need to use
an XSLT try/catch. This is available in XSLT 3.0 
(aka 2.1), and implemented
in Saxon 9.3: you will need the commercial edition.

Incidentally, if you are
using the same stylesheet to process many files, I 
recommend reusing the JAXP
Templates object, but creating a new Transformer 
object for each
transformation.
