How to Use regular expression in VC6?

Hi Community,

How can I use regular expression in VC6? I tried below sample code but it gives me an error as VC6 not supported atlcoll.h.

// catlregexp_class.cpp
#include <afx.h>
#include <atlrx.h>

int main(int argc, char* argv[])
{
    CAtlRegExp<> reUrl;
    // Five match groups: scheme, authority, path, query, fragment
    REParseError status = reUrl.Parse(
        "({[^:/?#]+}:)?(//{[^/?#]*})?{[^?#]*}(?{[^#]*})?(#{.*})?" );

    if (REPARSE_ERROR_OK != status)
    {
        // Unexpected error.
        return 0;
    }

    CAtlREMatchContext<> mcUrl;
    if (!reUrl.Match(
"http://search.microsoft.com/us/Search.asp?qu=atl&boolean=ALL#results",
        &mcUrl))
    {
        // Unexpected error.
        return 0;
    }

    for (UINT nGroupIndex = 0; nGroupIndex < mcUrl.m_uNumGroups;
         ++nGroupIndex)
    {
        const CAtlREMatchContext<>::RECHAR* szStart = 0;
        const CAtlREMatchContext<>::RECHAR* szEnd = 0;
        mcUrl.GetMatch(nGroupIndex, &szStart, &szEnd);

        ptrdiff_t nLength = szEnd - szStart;
        printf_s("%d: \"%.*s\"\n", nGroupIndex, nLength, szStart);
    }

    return 0;
}

To the best of my knowledge that class (CAtlRegExp) is only available for more recent versions of visual studio.
Two options:
Get a newer version of visual studio
Find a third party utility or write one yourself  (There should be regex support in the boost libraries for example)

You might want to try GRETA ("The GRETA Regular Expression Template Archive") for that purpose instead: http://research.microsoft.com/en-us/downloads/bd99f343-4ff4-4041-8293-34c054efe749/default.aspx
