It did process something but I am a little dumb how to use it. I put it in the same folder as my working file to begin with. I thought it could not harm.
roger@roger-laptop:~$ cd /home/roger/Bureau/pdfreflow-0.8.3/ubuntu/
roger@roger-laptop:~/Bureau/pdfreflow-0.8.3/ubuntu$ pdftohtml -xml Bowden\,\ Mark\ -\ Killing\ Pablo.pdf

But I do not know what to do with the resulting xml file. Sorry for that.
