Hi Guys,
Holliday took got me far away from my computer
@betterRed: thank you very much for pointing me in the subgrouping direction... I use command line for batch conversion, but nothing else right now
@theduck: whouah, the template is juste amazing... it sends me back to the old days when I had to juggle for the first time with regular expression not knowing what xpath was
I keep you posted on my experiments
Thanks a lot again for your detailed answers. I guess these two replies could become a good start for a tutorial.
François
