You didn't tell us which shell you are using. I don't know if your construction works in bash, but in ksh it won't:
typeset -A comp1=$(cat file1 | cut -d"|" -f2)
will produce an array with exactly one element from your files, as "typeset -A" uses whitespace as delimiter, not newlines. You will see that when you trace the script with "set -xv" and watch the output of "(cat file1 | cut ...)".
Then there is a logical error in your code: the "for str in .... done" cycles through every element of the array comp2[]. You compare each to every element of comp1[]: comp2[1] to comp1[1], then comp2[1] to comp1[2], ..., comp2[1] to comp1[n], comp2[2] to comp1[1], comp2[2] to comp1[2], ... This is probably not what you want to achieve - you want to compare comp1[1] to comp2[1], comp1[2] to comp2[2], etc. This is done by the following (demo-)code:
If you want to *search* in one file for the key you found in the other and don't rely on them being sorted according to the same key then do the following: cycle through one array, searching through the other one. If you find a corresponding value store the number of the array-element found. If this number is not stored you have not found a corresponding element. Again, in a sketchy demo-code:

stag-grep
STAG-GREP(1p) User Contributed Perl Documentation STAG-GREP(1p)NAME
stag-grep - filters a stag file (xml, itext, sxpr) for nodes of interest
SYNOPSIS
stag-grep person -q name=fred file1.xml
stag-grep person 'sub {shift->get_name =~ /^A*/}' file1.xml
stag-grep -p My::Foo -w sxpr record 'sub{..}' file2
USAGE
stag-grep [-p|parser PARSER] [-w|writer WRITER] NODE -q tag=val FILE
stag-grep [-p|parser PARSER] [-w|writer WRITER] NODE SUB FILE
stag-grep [-p|parser PARSER] [-w|writer WRITER] NODE -f PERLFILE FILE
DESCRIPTION
parsers an input file using the specified parser (which may be a built in stag parser, such as xml) and filters the resulting stag tree
according to a user-supplied subroutine, writing out only the nodes/elements that pass the test.
the parser is event based, so it should be able to handle large files (although if the node you parse is large, it will take up more
memory)
ARGUMENTS
-p|parser FORMAT
FORMAT is one of xml, sxpr or itext, or the name of a perl module
xml assumed as default
-w|writer FORMAT
FORMAT is one of xml, sxpr or itext, or the name of a perl module
-c|count
prints the number of nodes that pass the test
-filterfile|f
a file containing a perl subroutine (in place of the SUB argument)
-q|query TAG1=VAL1 -q|query TAG2=VAL2 ... -q|query TAGN=VALN
filters based on the field TAG
other operators can be used too - eg <, <=, etc
multiple q arguments can be passed in
for more complex operations, pass in your own subroutine, see below
SUB a perl subroutine. this subroutine is evaluated evry time NODE is encountered - the stag object for NODE is passed into the subroutine.
if the subroutine passes, the node will be passed to the writer for display
NODE
the name of the node/element we are filtering on
FILE
the file to be parser. If no parser option is supplied, this is assumed to a be a stag compatible syntax (xml, sxpr or itext);
otherwise you should parse in a parser name or a parser module that throws stag events
