I know this wasn't what you were looking for, but I hope this explanation helps!

Thank you, the truth always helps.

A hint for you: there is another writing mistake: "that" instead of "than" in "Often there is more that one way of matching".

That'll be fixed in cvs in a moment: thanks for pointing that out.

And the boost::regex::egrep option doesn't work. No match is found with:

regex expression1("<[^>]*>\n]*)>", boost::regex::egrep);

Yikes, that's a bad one to slip through, I'm testing (the fairly trivial) fix now.

I guess, even a working egrep option would not change anything for me.

Nope, you need to either: Use the perl-compatible expressions and place the alternatives in the order you want them searched, or Use POSIX expressions, and either put brackets around all the alternatives *and* put them in the order you want. Or don't put braces around those of lower priority, and do put them around those of higher priority. HTH, John.
