Simple regex help

Just wondering how to search a string for non word
characters that 
aren't spaces...
W is for a non-word character, s would find a space, just
wondering 
how to put that together in a regex...

Thanks much,

David

You can only "or" together in a char class (this
OR that).
But you want to "and".  Luckily, DeMorgan's laws
teaches us
that the following are equivalent:

        (this AND that)
        NOT (NOT this OR NOT that)

so it's just a matter of writing it out.  You want:

        (non-word AND non-space)

which demorgan says is:

        NOT (NOT non-word OR NOT non-space)

and reducing the nots:

        NOT (word OR space)

and writing that in regex talk:

        [ ^ w s ]

and removing the spacing:

        [^ws]

There ya go.  All the chars that are neither word nor space.
