StringRegExp Help

[confused2gether]

I am stuck at a certain point in my program that I need to extract a set of numbers from a specific string.

Here is are examples of some strings:

This is a (23.123, 34.567) great example of some code (yes it is).

This is another example of some code (34.234, 78.123).

Hello World (45.678, 12.324) This is cool.

I need to extract out the (##.###, ##.###) from each different string. The position is always different and the numbers are always different but the format is always the same. Also, in the first example, I need to make sure to not grab the "(yes if is)".

I have been looking around the forums and the help file and it looks like the thing to use is StringRegExp but I am very confused on how to write out how to grab that information specifically.

Any help is appreciated!

Thanks

try (\(\d+\.\d+,\s+\d+\.\d+\))

try (\(\d+\.\d+,\s+\d+\.\d+\))

Initial try looks like it works! Thanks for the help! It will help me better understand how this who RegEx actually works too for the future.

I didn't reply earlier because jchd had it all under control. If you want to learn and use Regular Expressions, try the PCRE Toolkit in my signature.

I've little to add to what GeoSoft said, but let me try to explain:

(\(\d+\.\d+,\s+\d+\.\d+\)) : the outer parenthesis actually mean capture what matches the inside.

\(\d+\.\d+,\s+\d+\.\d+\) : match a left parenthesis

\d+\.\d+,\s+\d+\.\d+\) : match one or more decimal digits

\.\d+,\s+\d+\.\d+\) : match a dot

\d+,\s+\d+\.\d+\) : match one or more decimal digits

,\s+\d+\.\d+\) : match a comma

\s+\d+\.\d+\) : match one or more space character

\d+\.\d+\) : match ###.### like we just did

\) : match a right parenthesis

It's just like Lego bricks!
