search inside zip archives

[mohfa]

Hi , i'm developping an application that its main goal is to search for a string inside zip archives ( it's like a Grep utility ).

for the first time i hade no problem when a zip archive is a single file ( i mean the zip archive contains only files ) , but the problem begins when a zip archive stores some other zip archives , i mean One zip archive that stores other zip archives .
the first solution i tought about is to make a recrusive search inside a zip archive but really i tried a lot of time but no result .

can someone helps me to make a recrusive search procedure inside a zip archive that stores other zip archives .



regards.
