Hello, I am new here, and hopefully someone here will be able to answer my question. I have this project that I am working on, and it is taking forever to try and complete. Basically, I have a bunch of long documents, they are transcripts of multiple people talking. I basically have to remove everyone's transcripts except for one person.

So With the example of the types of documents I'm working on below. I have to keep the same format, as far as the tape title and start to end timecodes, I have to delete what anyone says except for AA. Is there a way of accomplishing this via running a script? I have tons of files like this and theyre about 84 pages each document.

This is what they look like, and if you scroll down Ill post what its supposed to look like just in case my description of my problem isn't great.

[TAPE: 00001 - (99)]
Start 18:07:36;19 - End 18:07:47;27

AA: Hello, how are you sir.

BB: I’m doing great thank you.
--------------------------------
[TAPE: 00001 - (100)]
Start 18:07:47;28 - End 18:07:49;11

AA: Hey don’t do that!

BB: I’m sorry I didn’t mean to.
--------------------------------
[TAPE: 00001 - (101)]
Start 18:07:49;12 - End 18:07:55;11

AA: Did you catch American Idol last night?

BB: Yes.
--------------------------------
[TAPE: 00001 - (102)]
Start 18:07:55;12 - End 18:08:10;15

AA: I need to go to get something to eat, would you like to go with me?

CC: Yes, let’s go.
--------------------------------
[TAPE: 00001 - (103)]
Start 18:08:10;16 - End 18:08:13;25

AA: But he has to definitely give me a good price.

CC: We’ll cut you a very good deal.



And this is what it is supposed to look like.

[TAPE: 00001 - (99)]
Start 18:07:36;19 - End 18:07:47;27

AA: Hello, how are you sir.

--------------------------------
[TAPE: 00001 - (100)]
Start 18:07:47;28 - End 18:07:49;11

AA: Hey don’t do that!

--------------------------------
[TAPE: 00001 - (101)]
Start 18:07:49;12 - End 18:07:55;11

AA: Did you catch American Idol last night?

--------------------------------
[TAPE: 00001 - (102)]
Start 18:07:55;12 - End 18:08:10;15

AA: I need to go to get something to eat, would you like to go with me?

--------------------------------
[TAPE: 00001 - (103)]
Start 18:08:10;16 - End 18:08:13;25

AA: But he has to definitely give me a good price.
