Ok, regex was my first thought because I used to use grep with Perl and shell scripting to grab everything from one pattern to another pattern. The file is just an unformatted file. What is below is exactly what is in the file. There are no spaces between the beginning and ending tags and the content. Would you recommend using spaces there? And if so, why?
