[tpm] Regex assistance

[legrady]

How about if you split () on Co. Mas, and then just check the elements of the array for the values you want?
You pattern captures into separate variables : two digits, a dot, two digits, a dot, another two digits.  From your description you want to the whole thing: 
      /(\d{2}\.\d {2}\.\d {2})/
OR a bit sloppily,  but valid 
     /([0-9.]{8})/
It matches non valid strings,  but you say those won't happen. Or by adding an 'x' flag, you can comment your regex. 
    / (                     # capture        [0-9.] {8}      # 8 chars which are digit or dot        ) /'

Probably more useful in more complex instances.

Hello Perl Mongers,



I am looking for assistance with a regex. I have a bunch of strings in for form:



"01.03.16,,Studio one, Space 22,1         500,500,01.051,,"

or

",01.03.16,,Studio one, Space 22,1         500,500,01.051,"

or

",01.03.16,,Studio one, Space 22,1         500,500,01.051,,"

or

",01.03.16,,Studio one, Space 22, ,01.051,,"



So the middle section can be one or more comma separated strings.



I am trying to match and return the first non-blank pattern and the last non-blank pattern

01.03.16 and 01.051 – these numbering formats are always the same: xx.xx.xx and yy.yyy



So far I have a regex that matches the first pattern:



"([0-9]{2})([\.])([0-9]{2})([\.])([0-9]{2})"



In any of those above example.



I am stuck after that.

Any insights appreciated!
