[Solved] sed parsing xml file1 index file2

Question

the awk line should work for u:

awk 'FNR==NR{if(NR%2)i=$0;else a[i]=$0;next;}{if($0 in a){print; print a[$0]}else print}' file2 file1

EDIT

here I see no EXTRA lines. see the test. (maybe your example data format is not same as your real data.).

however I have shown the way, how to do it. you can change the awk oneliner to fit your real data format.
