I have a problem in accessing a specific tag without considering the same tag inside child nodes.

The problem is:
<bib>
<au>
<fnm> Jelfy</fnm>
<snm>Mary</snm>
</au>
<au>
<fnm> Sumitha</fnm>
<snm>Susan</snm>
</au>
<eds>
<au>
<fnm> Joy</fnm>
<snm>Peter</snm>
</au>
<au>
<fnm> Flora</fnm>
<snm>Sania</snm>
</au>

</eds>
</bib>
Here I want only Jelfy Mary and Sumitha Susan,the <au> inside <eds>
I dont want to extract.I used getelementbytagname,select singlenodes etc but it is fetching all the 4 au tags.
I want only the first 2.Can u help me?
