[Rajasekaran, Santhosh]

Hi Folks,

                I have the below requirement in Xquery.

Given a string I need to remove spaces, punctuation, parens and etc., 
(I.e)except alpha(A-Z or a-z) and numeric 0-9

Eg:

Input                                       Expected Output

San & co.,                              Sanco
It is a string                            Itisastring
New (value)                          Newvalue
At,the hill +  school             Atthehillschool
Oh!.. is it, I don’t know       OhisitIdontknow

Please let me know how do I achieve this. Do I need to add all this characters 
(spaces,punctuation,parens and etc., in regular expression and replace that one 
by one) using fn:replace() function.
Or
Do we have any other better suggestion?

Thanks & Regards,
Santhosh
