Post your code and a couple of lines of data. The examples given _do_ work. Perhaps we are missing a part of the problem?
#!/usr/bin/perl
while ( <DATA>) {
($a,$b) = split ' ';
print "split '$a','$b'\n";
my ($a,$b) = $_ =~ /(\S+)\s+(\S+)/;
print "match '$a','$b'\n";
}
__DATA__
none bing
some bong
any bang
output:
split 'none','bing'
match 'none','bing'
split 'some','bong'
match 'some','bong'
split 'any','bang'
match 'any','bang'
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
