Re: isolating text in a string

Hi,

Hello,

I'm trying to isolate text in a string. My string is typically of the
form:
sometext["moretext",

I would like to isolate moretext.

I tried:
#!/usr/bin/perl -w
my $string = 'sometext["moretext",';
print $string;
my $snippet;
($snippet, $snippet) = split(/$string/,\[,2);

I assume that you really meant to say:

( $snippet, $snippet ) = split /\[/, $string, 2;

But why are you using the same variable twice in the assignment list? Perhaps you meant this instead:

my ( undef, $snippet ) = split /\[/, $string, 2;


print "$snippet\n";

I don't seem to be able to escape the [ in the split function, so two
questions:
1. How do I escape the [?

See above.

2. What would be a better way to approach this problem?

Is 'sometext[' always the same or variable? Is 'moretext' always enclosed in double quotes and preceded by [ and followed by ,?

Perhaps:

my ( $snippet ) = $string =~ /\w\["([^"]+)",/;
