Thanks David,

I am new to function and sequence functions. However the code is
working fine for author which is having cross-ref tag with affiliation
ids.

But it is failing at the examples below:

<author-group>
    <author>
         <given-name>Shaked</given-name>
         <surname>Gilboa</surname>
    </author>
    <affiliation><textfn>Department of Business Administration, Ruppin
Academic Center, Emek Hefer 40250, Israel</textfn></affiliation>
</author-group>

In which there is no cross-ref and there is no id in affiliation as
this is the single occurrence in the file. This can also define as,
when there is a single affiliation without any id by default the
country should be displayed after the author name(s).

Another variation in the input is as follows:

<author-group>
  <author>
    <given-name>Arch G.</given-name>
    <surname>Woodside</surname>
    <cross-ref refid="aff1"><sup>a</sup></cross-ref>
    <cross-ref refid="cor1"><sup>&#x204E;</sup></cross-ref>
  </author>
  <author>
    <given-name>Timucin</given-name>
    <surname>Ozcan</surname>
  </author>
  <affiliation id="aff1"><label>a</label><textfn>Department of
Marketing, Boston College, Carroll School of Management, 140
Commonwealth Avenue, Chestnut Hill, MA 02467,
USA</textfn></affiliation>
  <affiliation id="aff2"><label>b</label><textfn>Department of
Management and Marketing, Southern Illinois University-Edwardsville,
Founders Hall 2120, Edwardsville, IL 62026, USA</textfn></affiliation>
</author-group>

For one there is cross-ref and for another there is no. In these cases
also it should do the grouping.

Please guide me further on this problem.

Regards,
Ganesh
