Hello All.
I'm using the C++ library of boost RegEx. Long story short: I'm trying the expression
(?<=<h1>).*?(?=</h1>)
On the string <h1>hello there</h1>
and the engine crashes (asserts in Kernel32(d).dll)
Is this a known issue?
here's my code snippet.
std::vectorstd::string v; boost::RegEx expr( "<h1>hello there</h1>", TRUE); expr.Grep(v, "(?<=<h1>).*?(?=</h1>)" );
thanks for any help!
