How can I retrieve the text between <id> and </id>? I tried using:
sed -e 's/<id>(.*)</id>/1/'
but that results in the entire block of text being printed out instead of just the part between and <id>.
I don’t have the ability to install programs on this box so I’d rather not go through the hassle of manually compiling xmlstarlet, etc, just to extract this one thing.

Thanks for explaining why you are not doing the obvious with the correct tools
sed -e 's/.*<id>(.*)</id>.*/1/'
match what you don’t want too (untested)
