redact - pattern

I have found the file named SearchRedactPatterns.xml (thank you) and I just started trying to make sense the code defining text pattern. (I also need to get rights to modify this file - it's locked.)

I want to add a pattern that fits a pair of numbers (latitude and longitude). The pattern is always a pair, comma and space separate the pair, second number preceeded by negative sign. There are two digits before the decimal point. The number of digits after the decimal points will change - so I guess I define more than one pattern - but even with a single, new pattern fitting the example below, I would have saved myself work and saved myself time.

Example pattern:

36.63, -82.551

I found a website that explains text searches usin regular expressions (RegEx) -

http://www.Regular-Expressions.info/

Looks like the RegEx code at this "info" website is similar to the text pattern code in the Adobe xml file (SearchRedactPatterns.xml).

I need to match and redact a Lat. and Long. coordinate pair such as:

36.63, -82.551               (fixed length)

36.6nnn, -82.5nnnnn       (variable length)

I want to try my code (untested code - don't know if it is correct), first matching a fixed length pair, second matching variable-length :

<val>(\d\d.\d\d\,\ \-\d\d\.\d\d\d\)</val>

<val>(\d\d\.\[0-9][0-9]{0,4}\,\ \-\d\d\.\[0-9][0-9]{0,6})</val>
