Look at the man for "chop()" function, it does exactly what you want, example :
Code:
#!/usr/bin/perl

my $string = 'frog';
my $chr = chop($string);

print "String: $string\n";
print "Char: $chr\n";

this outputs :
Quote:
String: fro
Char: g
you should, of course, removing this part : "print "Char: $chr\n""

Edit : if you want array :
Quote:
my @array = qw/fred bob jill joan/;
my $chr = chop(@array);

foreach my $str (@array) {
print "$str\n";
}

print "Char: $chr\n";

XML::LibXML::RegExp(3)					User Contributed Perl Documentation				    XML::LibXML::RegExp(3)

NAME
XML::LibXML::RegExp - XML::LibXML::RegExp - interface to libxml2 regular expressions SYNOPSIS
use XML::LibXML; my $compiled_re = new XML::LibXML::RegExp('[0-9]{5}(-[0-9]{4})?'); if ($compiled_re->isDeterministic()) { ... } if ($compiled_re->matches($string)) { ... } $compiled_re = XML::LibXML::RegExp->new( $regexp_str ); $bool = $compiled_re->matches($string); $bool = $compiled_re->isDeterministic(); DESCRIPTION
This is a perl interface to libxml2's implementation of regular expressions, which are used e.g. for validation of XML Schema simple types (pattern facet). new() $compiled_re = XML::LibXML::RegExp->new( $regexp_str ); The constructor takes a string containing a regular expression and returns a compiled regexp object. matches($string) $bool = $compiled_re->matches($string); Given a string value, returns a true value if the value is matched by the compiled regular expression. isDeterministic() $bool = $compiled_re->isDeterministic(); Returns a true value if the regular expression is deterministic; returns false otherwise. (See the definition of determinism in the XML spec (http://www.w3.org/TR/REC-xml/#determinism <http://www.w3.org/TR/REC-xml/#determinism>)) AUTHORS
