Wawan, is it true that you look at postings only, not on your ingoing e-mail?

Have you *reasoned* why you want do the replacing with LaTeX, not with Perl?

Besides an algorithm, you need an implementation -- that actually operates
on strings. You need macros referring to strings und substrings. This has
(almost) nothing to do with implementing "if" and "then" as ifthen does it.
Indeed, the first argument of \ifthenelse needs a *test* referring to
certain things. The ifthen package implements tests of equality of strings,

The xifthen package adds tests for substrings, but it doesn't implement any
*operations* on strings, i.e., generate a certain output string from some

There is a guide for class and package writers at
and a section on the same matter in the LaTeX Companion. And finally CTAN
is full of examples.
All the best,
