get characters from output of a command in a variable

Hi,

i have two questions, I am new to programming
1. I have an output of a command and i want to get some specific part of it in a variable. i am trying

sr=`some comand xyz| grep 'Last Changed Rev:' | cut -c19-`
now variable sr gets a end of line character at end.

output of the command is

Date: yyyy-mm-dd
---------

abc
xyz
Last Changed Rev: 10
abc
-------------

i want to get this 10 in the variable sr. i dont know the number length in advance.

2. Also the comand returns multiple lines output, how to get complete text in between

abc
xyz
Last Changed Rev: 10
abc

in another variable?
please help!

Thanks in advance..
