And excuse me, but you ARE using regular expressions in your example...<BR>

<BR>
you don't need regex:<BR>
<BR>
sed \<BR>
-e '/^ *$/d' \<BR>
-e 's/,/ \& $/' \<BR>
-e 's/\./,/g' \<BR>
-e 's/e/ \\cdot 10^{/' -e s'/$/}$\\\\/' \<BR>
/path/to/input/file<BR>
<BR>
now, the exercice is to read the input file directly with LaTeX using<BR>
TeX macros instead of converting it.<BR>
