with the: (.*\<)? doesn't the ? match 0 or 1 occurences of anything in the
()? if so how does that work with the (.*) characters since .*
means 0 or more occurences of any character? Don't the .* and the ?
contradict each other since the ? applies to anything in the ()?
No, the (.*\<) expression matches at least one character (the boundary
character after .*) but we also want to match nothingness, so we make
the whole expression optional. You might be able to find more about
this in the archives.
