[ROOT] Regular expression in string

Hi,

The TString class has a nice feature which is the detection
of a regular expression within a string:

	Bool_t Contains(const TRegexp& pat) const

Once a regexp has been detected is it possible to store this
expression to a variable?

For example for the two strings:

	TString str1 = "_15GeV_"
	TString str2 = "_30GeV_"

the following results will be true:

	str1.Contains("_[0-9][0-9]_GeV")
	str2.Contains("_[0-9][0-9]_GeV")

Can someone finds out which string is actually matched?

Thanks!

Stelios.
