A regular expression that only matches nothing?

[steve.chambers]

Can such a thing be done?

To explain myself a bit better I need a regular expression that will
only match an empty string ("") - if there is any text in the string I
don't want it to match. Won't go into why, it would take too much
explanation!

Thanks for any help/suggestions...

Cheers,
Steve

Pattern empty = Pattern.compile("^$");

..{0}

Both seem to work, not sure which is best but will probably go with the
..{0} suggestion as its meaning seems slightly more intuitive.

Thanks v. much to both of you for the helpful suggestions.
