[Dev-C++] Regular expressions: string substitution with pcre or any other library?

[Bernd M. <Ber...@eu...>]

Hi together,
most of the time I'm using .net framework to programm C++.
F.E. I can do the following:

Regex* rex;
String*=20
replacedTags=3Drex->Replace(originalLine,S"<(.*)?>,S"<SPECIAL>$1</SPECIAL=
>");

For a special program I would like to do the same in a standard C++ progr=
am.
I found the library pcre and after some starting problems I'm able to=20
compile and link to it.
But with this library I can only test if a string matches to a pattern=20
and extract the corresponding substring.
I think I would be able to write a function for replacing this=20
substring, but there must have someone before me who did this work=20
already ;-)

Searching with google "pcre string replace substitute" or whatever I did=20
not find any solution for pcre nor any other library for the same thing=20
(it must be a library which can be used with Windows XP).

Thank you for any hints, Bernd

never used them myself, but the boost libraries may be very helpful...

Why not use Boost.Regex? regex_replace() will probably do what you want.
