Advanced find and replace text in photoshop

In photoshop, let's say I have a few texts layers with contents like this:

Text layer 1: 1@@text01@@abc
Text layer 2: 2@@text02@@cef
Text layer 3: 3@@text03@@hgi

I would like to replace all the layers texts starting with the first@ and the end @, that is "@@text..@@" to "##,

so that results will be:

Text layer 1: 1##abc
Text layer 2: 2##cef
Text layer 3: 3##hgi

I know that photoshop has the "find and replace" function, but it seems only to replace a string/text in a simple way. That's why I would like to know if there is a photoshop script that can do this in a quick way.

Thank you.
