Dear Monks,

today I have played around a bit with HTML::Tree and its parts. And was surprised that the following expression was not working (as intended) on a string extracted from a webpage using as_trimmed_text().

$name =~ s/\sx\s\d+//;  # remove trailing " x 3" (and similar)
[download]

After a lot of searching I found the culprit: the blanks were coded as 0xA0 (non-breaking spaces). And \s is not matching them. Is there a better way to handle those besides my rather ugly solution below?

$name =~ s/[\s\xA0]x[\s\xA0]\d+//;
[download]

Or another workaround?

Rata

Update: Thanks a lot rovf, Eliya and LanX: I added all of your solutions to my code for future reference - all work like a charm :-) Now that I installed v5.14, I will keep the solution with use feature "unicode_strings"; active - I like its elegance.

And thanks for the link to the interesting blog-post, shawnhcorey!
