Hi,
Can anyone help me to find regular expression for the following in Perl?
"The string can only contain lower case letters (a-z) and no more than one of any letter."
For example: "table" is accepted, whether "dude" is not.
I have coded like this:

locale::currency
Locale::Currency(3pm) Perl Programmers Reference Guide Locale::Currency(3pm)NAME
Locale::Currency - standard codes for currency identification
SYNOPSIS
use Locale::Currency;
$curr = code2currency('usd'); # $curr gets 'US Dollar'
$code = currency2code('Euro'); # $code gets 'eur'
@codes = all_currency_codes();
@names = all_currency_names();
DESCRIPTION
The "Locale::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in ISO
4217.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217
three-letter codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying currencies. A code set may be specified using either a name, or a
constant that is automatically exported by this module.
For example, the two are equivalent:
$curr = code2currency('usd','alpha');
$curr = code2currency('usd',LOCALE_CURR_ALPHA);
The codesets currently supported are:
alpha, LOCALE_CURR_ALPHA
This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro.
Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no
currency is involved) are omitted.
This is the default code set.
num, LOCALE_CURR_NUMERIC
This is the set of three-digit numeric codes from ISO 4217.
ROUTINES
code2currency ( CODE [,CODESET] )
currency2code ( NAME [,CODESET] )
currency_code2code ( CODE ,CODESET ,CODESET2 )
all_currency_codes ( [CODESET] )
all_currency_names ( [CODESET] )
Locale::Currency::rename_currency ( CODE ,NEW_NAME [,CODESET] )
Locale::Currency::add_currency ( CODE ,NAME [,CODESET] )
Locale::Currency::delete_currency ( CODE [,CODESET] )
Locale::Currency::add_currency_alias ( NAME ,NEW_NAME )
Locale::Currency::delete_currency_alias ( NAME )

Locale::Currency::add_currency_code_alias ( CODE ,NEW_CODE [,CODESET] )

These routines are all documented in the Locale::Codes::API man page.
