Your code as posted (almost) works. After modifying it to
#!/usr/bin/perl -w
use strict;
my $out = '<?xml version="1.0" encoding="utf-8"?>';
my @tmp = split /</, $out;
foreach(@tmp) {
if (substr($_, 0, 1) eq "?") {
print "conditionA matched - looping!\n";
next;
} elsif (substr($_, 0, 1) eq "!") {
print "conditionB matched\n";
}
print "End of loop\n";
}
I get the output
End of loop
conditionA matched - looping!
as expected. (Note that the split is returning a list of
two scalars, not just one: the 0 characters before the < and
the
n characters after it.)
Side note: That feels a lot like C. Changing your tests
to if (/^\?/) and if (/^!/) would
feel perlier. Should work either way, though.
