I don't believe that's a string, m_pimpl is just the name of the single 
variable in the regex object that points to it's internal data, but I 
repeat: *you cannot easily see the stored regular expression in the 
debugger*, you will need to call the str() member function or else 
stream to cout or clog or something to extract that information.

I'll need the contents of the string that you are trying to match 
against as well to explain why no match occurs.

John.

Ok, update, you might be able to get to the stored expression via:

childNode.infoNode.rFullPathFilePattern.m_pimpl.px->m_expression

or maybe not...
