I added a couple of regular expression validators to my asp fields but
I am having difficulty coming up with a regular expression for this,
anyone have any suggestions?
My RegEx-Fu is very poor.
Any kind of latitude / longitude regular expression would be nice,
preferably one that uses the signed and unsigned decimal as opposed to
cardinal direction.
I have googled this for a while but can't find any example to use as a
good starting point.
(\d{1,3} \d{1,2}\.\d{1,2} [NSEW])
latitude or longitude coordinates in the form 46 37.73 N
but I would rather have this be something closer to:
46°37'73" (46 37.73 S would be better as -46°37'73")
Again, any feedback is appreciated.
