Forums Developers regular expression

Hey all, I am having a little trouble with my regular expression.
(I am programming in Java)

does anyone know why my regular expression:
p = Pattern.compile("«\\d+\\s(mb|m|meg|k|kb|gb|gig|g)»",Pattern.CASE_INSENSITIVE);

will not match this text?
«150 MB»

Thanks! I am stumped

i think that you should use \d instead of \\d (and \s instead of \\s)

\\ = 'escaped' \, an \ without its proprieties

There's two levels of parsing going on and backslash is the escape character in both of them. The extra backslashes are to escape the other backslashes when the string is parsed so that they're still backslash literals when the regular expression is parsed.
