Dear Monks,

I've the following issue:
$str = abc dddd    10 ;
$str1 = "abc dddd ee    10" ;

[download]

I need to extract "10" however there might be 2 or 3 words preceding. Somehow I cannot construct the regexp. My quess was something like:
$number = $str =~ /abc\sdddd\s[ee]\s+(\d+)/gs ;
but it didn't work:(
Furthermore I realized that I don't understand the ?:, ?= etc patterns. I tried to read the perlre but that didn't help very much
Any suggestions for a good tut or an other post ?

Thanks in advance
Luca
