Extracting Data from a .txt file

Hi

I am trying to copy several rows of data from a text file. I have had a look through previous threads and cant find anything that explains how to copy more than one row over so I am hoping someone else can help me.

I have a large text file - I have attached a small extract. So far I have managed to search the file and import the digit 1 out of the first row "Matrix 1" (trust me thats progress). The next step I want to do is literally copy the proceeding 109 rows. Is this possible - I know I could do it manually but I have 350 files with a minimum of 16 of these matrices in each.

Hope you can help

Thanks
