Problem with regex

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks, I want to know how to write a regex to first find a pattern in a line and then capture the value just next to it. example $line = "this is a test=234567 line"; Here i want to search for the pattern "test" and then get the value 234567 in a variable. I tried this ($value) = $line =~ /.*test=(\d+)/; but this does not seem to be working. Can any one explain how to get what i expect. Thanks in advance. regards, Sid

I don't know what your problem is. When I try: `use strict; my $line = "this is a test=234567 line"; my ($value) = $line =~ /.*test=(\d+)/; print $value;` [download] I get nicely: `234567` [download] pelagic	[reply] [d/l] [select]

I got the correct value when I tried this `use strict; my $line = "this is a test=234567 line"; if ($line =~ /.*test=(\d+)/){ print $1; }` [download] result `234567` [download] Good Luck!!	[reply] [d/l] [select]

I tried this ($value) = $line =~ /.test=(\d+)/; but this does not seem to be working.* In which way does it "seem not to work"? As mentioned by two other monks, it should! As a side note `/test=(\d+)/` should be perfectly equivalent to your code...	[reply] [d/l]

Re: `/.*test=(\d+)/ and /test=(\d+)/` ,of course, these are not entirely equivalent for other values of `$line`	[reply] [d/l] [select]

Now that I think about it you're right. Sorry for the imprecision...	[reply]
