Are you sure you tried a Perl script, the following seems to work (Tested on Solaris 5.10 sparc with Perl-5.8.4)
Code:
skrynesaver@busybox ~/tmp$ perl -w -Mstrict -e 'open my $long , ">" , "longLines.txt"; for (0..30000){print $long "<record><field1>data</field1><field2>other data </field2></record>";}'
skrynesaver@busybox ~/tmp$ wc  longLines.txt
      0   60003 1980066 longLines.txt
skrynesaver@busybox ~/tmp$ perl -w -Mstrict -e 'open(my $long, "<", "longLines.txt") || die "Could not open longLines.txt $!\n";my $data=readline($long);close $long;$data=~s/<record>/\n<record>/g;open my $short, ">", "shortLines";print $short $data;close $short'
skrynesaver@busybox ~/tmp$  wc  shortLines
  30001   90003 2010067 shortLines

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines - Use concatenation or HEREDOCs instead of literal line breaks in
       strings.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Strings with embedded line breaks are hard to read.  Use concatenation or HEREDOCs instead.

	   my $foo = "Line one is quite long
	   Line two";					 # Bad

	   my $foo = "Line one is quite long
Line two"; # Better, but still hard to read

	   my $foo = "Line one is quite long
"
	       . "Line two";				   # Better still

	   my $foo = <<'EOF';				 # Use heredoc for longer passages
	   Line one is quite long
	   Line two
	   Line three breaks the camel's back
	   EOF

CONFIGURATION

       This Policy is not configurable except for the standard options.
