Piping commands using xargs

Need help in piping commands using xargs

I have several .tar.gz files that I need to list the folder content in a subdirectory.
For example,
Code:
a.tar.gz
b.tar.gz
c.tar.gz

The following command works great for each .tar.gz file but it's a pain to run the tar command for each file.
Code:
tar -tf a.tar.gz|grep folder1/folder2

I tried this command and failed.
Code:
ls *.tar.gz|xargs tar -tf|grep folder1/folder2

I got this error message "tar: a.tar.gz: Not found in archive" for each gz file.

What do I need to fix to run this command successfully?
Or do I need to use a different command to process all the .tar.gz files?

Thank you.
