What you want is called "command substitution".  There are two different
syntaxes for this: backticks (deprecated) and $( ).

    myvariable=$( xmllint --whatever "$myfile" )

As others pointed out recently, there must NOT be any whitespace before
or after the = sign in a variable assignment.

The spaces that I put after $( and before ) are allowed, but not required.
