Re^4: remove line feed at the end

[Anonymous Monk]

<ROOT> <FILE>sourcetag1</FILE> <NUMBER>00000 11111</NUMBER> <SOURCE>source1</SOURCE> <AUTHOR>author1 staff1</AUTHOR> <HEADLINE>DISPOSABLE DECOR: THE CUTTING EDGE DULLS FASTTYLE AT A SPEED USUALLY ASSOCIATED WITH WARDROBE ITEMS</HEADLINE> </ROOT> Sorry...It is not only for the line which has \ at the end. It should remove all the new line character anything which doesnot match {sometext} at the start. I mergeed the code with the sample which you provided. But it works for the line {HEADLINE} The merged code is below

#!/usr/bin/perl
use strict;
use warnings;

my $output = '';
my $tag;
my $fh;
LINE: while ( my $line = <DATA>)  {
    chomp $line;
    # if line ended with a '\', remove '\' and save line for later out
++put
    if ( $line =~ s/\\$// || $line =~ s/\s$//) {
        # clean indentation
        $line =~ s/^\s+/ /;
        # save line
        $output .= $line;
        next LINE;
    }
    # we have previous line(s) to consider?
    if ( length $output ) {
        # clean indentation
        $line =~ s/^\s+/ /;
        $line = $output . $line;
        $output = '';
    }
  if($line =~ /^{(.*)}/) {
        $tag = $1;
    }else {
        if($tag eq 'FILE') {
                if(defined($fh)){
                print $fh "</ROOT>";
                close($fh);
                }
 my $filename = $line;
            open($fh, '>', "$filename.xml") or die "$filename: $!";
            print $fh '<?xml version="1.0"?>',"\n";
            print $fh "<ROOT>\n";
            print $fh "<FILE>$filename</FILE>\n";
        } elsif(defined($fh)) {
if($line ne ''){
$line =~ s/\\//gi;
            print "<$tag>$line</$tag>\n";
}
}
}
    print $line, $/;
}

Your code seems that concatenating of lines is only for the last statement before the {FILE} tag. Figure out the way to solve it.
