Hi Team,
Is there any quick idea about how to sequence the authors in the output
file.

Input
<article>
<author seq="1">author 1</author>
<author seq="3">author 3</author>
<author seq="2">author 2</author>
</article>

Desired output
<article>
<au seq="1">author 1</author>
<au seq="2">author 2</author>
<author seq="3">author 3</author>
</article>

Thanks in advance
