正则表达式匹配谷歌地图纬度

Question

I am using google map and i need to update map using lat long and to verify that some doesn't put invalid data i want a regex which can test entered lat long

But now when i see there are three type of lat long as described here

Google Map Lat Long Search

I made a regex for Decimal degrees (DDD) which is following

^([-+]?\d{1,2}([.]\d+)?),\s*([-+]?\d{1,3}([.]\d+)?)$

But this regex doesn't fulfill

Degrees, minutes and seconds (DMS): 41° 24' 12.1674", 2° 10' 26.508"

AND

Degrees and decimal minutes (DMM): 41 24.2028, 2 10.4418

So in simple i need regex to verify all these three types

Answer 1

You can add an OR operator |

^ anchor beginning
(?: start a non-capturing group
([-+]?\\d{1,2}([.]\\d+)?),\\s*([-+]?\\d{1,3}([.]\\d+)?) Your current regex.
| OR
Make one for degrees & minutes & seconds
| OR
Make one for degrees and decimal minutes
) end non-capturing group
$ anchor end

Let me know if you have more questions on this.
