Re^2: Substr warning

Hi,

I am extracting information from a html-site, which I have stripped of tags, etc. beforehand. In this instance, I am interested in the two words following the string "Rapporteur: ".

There is probably a better way of doing it, but at the moment I am using $' to get the text after the string I searched for and then read in every single character once at a time, add it to my variable until there have been two character that equal " " (thus, I have two words).

I am confused about the substr warning as I am sure, that there are plenty of characters left in the substring.

Hope this makes my dilemma clearer.

Yes it does. You can (and should) do this by a single regex. Like this: `if ($html =~ /Rapporteur: (\S+ \S+)/) { $reporters_name = $1; }` [download] The regexp searches for "Rapporteur:" followed by a single space, then some non-space characters, a single space and again some nonspace chars. And it captures those two groups of nonspace characters.
