Suppose I have the following string:

"The street is 1501 S. Oak Lane, Apt #228"

I need code that would extract the first numeric
substring (starting from the LEFT). Therefore, I
would need to extract "1501 from this string.

Or, I might have a string that looks like this:

"cat. dog mouse 12 8 112 house tree"

For that string, I would need to extract the "12"
only, because it is the first numeric substring or token.

Does anyone have any code samples that can extract
the substring that I describe above?? Please note
that any number of whitespace (space or tab) characters
may separate the string elements.

Thank you!
