Re: [Regexp] (no subject)

[Hartwig, Thomas]

If I understand you correct. You can catch this with repeating 
operators. See this from the manual:


-----------------------------------------------
# Repeating Operators
These symbols operate on the previous atomic expression.

    ? matches the preceding expression or the null string
    * matches the null string or any number of repetitions of the 
preceding expression
    + matches one or more repetitions of the preceding expression
    {m} matches exactly m repetitions of the one-character expression
    {m,n} matches between m and n repetitions of the preceding 
expression, inclusive
    {m,} matches m or more repetitions of the preceding expression
-----------------------------------------------



[a-zA-Z0-9,.'&@_-]{2,} would catch all occurences of at least two of 
your character class.
