Add file name+path to processed document

Hello,

in my ANT processing pipeline I process a folder structure full of XML
documents. One task is to add the file name and path to each processed
file via XSL. Is there a way to extract the name and path of the
currently processed file from the processor and write it to the output
document. It does not need to be standard XSLT becaused inside ANT I am
able to switch processors.

Any idea would be great!
