[OSM-dev] Script to find tiles that need rebuilding

[OJW]

BlueNinja was having problems with western-hemisphere locations showing-up in 
the RSS feed as if their latitude had been inverted

I'm looking at a line in the script:

  if( $part =~ m,<geo:lat>-?([0-9.]+)</geo:lat>, )
  {
    $lat = $1;
  }

and wondering if it should be replaced with:

  if( $part =~ m,<geo:lat>(-?[0-9.]+)</geo:lat>, )
  {
    $lat = $1;
  }
