So, something like: #!/usr/bin/perl use strict; my $svg; my $file = shift or die "Usage: $0 file\n"; open IN, $file or die "Can't read $file\n"; $svg .= $_ while (<IN>); close IN; $svg =~ s/^\s+//; $svg =~ s/\s+^//; $svg .= "\n"; $svg =~ s/\s+/\n/g; $svg =~ s/\>\s+\</\>\n\</g; print $svg; would then work? An option would be to make git optionally aware of svg, avoiding long lines there. > You can use tidy or xmllint to clean up the xml before > committing. Unfortunately I couldn't make tidy actually wrap the long > attributes, but could be PEBKAC. I tried both, none broke the long lines on Documentation/media/uapi/v4l/fieldseq_tb.svg.
