Question Need help with sed and regexp

Hi everyone, I would really appreciate any help I could get on the following topic.
I am not very familiar with reg expressions nor with sed, I just know the basic uses. What I am trying to do is the following: I have a huge text file where I would like to replace all occurnces of a certain pattern with another one. Here an example:

Code:
 "name1" = "12;15";
  "name5" = "7";
  "abc1" = "3";
  "5" = "";
  "-7" = "";
  "hgf" = "12;15";
  "e1" = "8";
  "-5" = "";

Should change to:

Code:
  "name1" = "12;15";
  "name5" = "7";
  "abc1" = "3;5;-7";
  "hgf" = "12;15";
  "e1" = "8;-5";

The rule is: any assign statement to a variable starting with a letter ( like "name1" ) is preserved, while any assignment to a numerical variable ( like "1" or "-1" should be appended to the previous line.

I couldnt get it to work because of the condition is across more than one line. I know I am supposed to use the N instruction but dunno how. Any help how to do the above with sed or any other way is cery appreciated.

Thanks.

Locale::Currency(3)					User Contributed Perl Documentation				       Locale::Currency(3)

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::rename_currency_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Currency::add_currency_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Currency::delete_currency_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
