is this what you require ?

Code:
while read a
do
grep -i "$a" file1
done  < file2

@zozoo small modification to your script

Code:
$ while read a; do a=$a"xml.gz"; grep -i $a file1; done  < file2
abc.xml.gz
X.xml.gz

awk you may try

Code:
$ awk 'FNR==NR{A[tolower($1"xml.gz")];next}(tolower($1) in A)' file2 file1
abc.xml.gz
X.xml.gz

Or something like this?
Code:
awk -F\. 'NR==FNR{a[toupper($1)]; next} toupper($1) in a' file2 file1

@ Franklin52 yes., it works but if extension is other than .xml.gz or file without extension with same base name also will be printed.

How about
Code:
grep -iFf file2 file1
abc.xml.gz
X.xml.gz

?

Without an anchor "^$a" or "$a"xml.gz one can keep it simple
Code:
fgrep -if file2 file1
