Reading text file, comparing a value in a line, and placing only part of the line in a variable?

I need some help. I would like to read in a text file. Take a variable such as ROW-D-01, compare it to what's in one line in the text file such as PROD/VM/ROW-D-01 and only input PROD/VM into a variable without the /ROW-D-01. Is this possible? any help is appreciated.

unwrapdiff

UNWRAPDIFF(1)							     Man pages							     UNWRAPDIFF(1)

NAME

       unwrapdiff - demangle word-wrapped patches

SYNOPSIS

       unwrapdiff [-v] [file...]

       unwrapdiff {[--help] | [--version]}

DESCRIPTION

       unwrapdiff demangles patches that have been word-wrapped, in an attempt to make them useful.

       The corrected diff is sent to standard output. Note that you will probably need to use the -l option when applying the patch, in order to
       ignore any whitespace differences there may be.

OPTIONS

       -v
	   Verbose operation. A list of lines that are modified in a way that might be wrong is sent to stderr.

       --help
	   Display a short usage message.

       --version
	   Display the version number of unwrapdiff.

LIMITATIONS

       Some heuristics are used to decide whether use a space to recombine a wrapped line, or just join them together. Currently this is done by
       comparing with last three characters of a line with the first two characters of its continuation, and using a space if any of them are
       different.

       The patch needs to have been valid before being word-wrapped.

       The last line of a hunk is nearly always ambiguous. If the next line begins "@@", "Index: ", "diff " or "--- " then it is taken to be
       complete; otherwise it is unwrapped using the next line.
