Need help with some string manip in C#

<< < (2/2)

mwb1100:
I think the following algorithm will get you what you want (or close):

  - remove any characters that are not an alpha, a digit, or a decimal point
  - replace runs of alpha characters with a space

Now you have a space-delimited string of the numbers you're looking for.

Some things that might need work or modification:

  - if you want to allow negative numeric values, then you might need to handle the minus sign specially (you discarded it in my question's example, so I figure you're not interested in negative values)
  - if you want to allow a comma to be used as a decimal separator

But I think the basic idea gets you what you're looking for.

mouser:
I think a regex is the way to go.  Easy to make one that ignores whitespaces, etc.

Renegade:
That looks workable,  Ren. But any regex would need to capture and replace whitespace before,  among and after the numbers: "9. 07" becomes "9.07", and " 7   6 . 04" becomes "76.04"

While you can do something like:

( )?([0-9 ]+)\.([0-9 ]+)( )?

You can also concat the capture groups and use string.Trim() or string.Replace(). That's simple and reliable.

kyrathaba:
Yeah, I installed Regulator, but I really need to do some studying of regexes.

RegexHero is another you might want to try.  Regexbuddy is the best Regex editor that I've come across.
