OK, now we're getting somewhere, how about an example of the output you want?

Here is a simplified example:

<authors>
<author fnref="fn1" affref="aff2" paref="par1">
  <sequence>1</sequence>
  <fname>K.</fname><lname>Lspez-Bujol</lname>
  <footnote id="fn1">These authors contributed equally to this work.</footnote>
</author>
<author affref="aff1 aff3" corresponding="yes" fnref="fn1">
  <sequence>2</sequence>
  <fname>F.</fname>
  <lname>Zhang</lname>
</author>
<author affref="aff1 aff2" fnref="fn1">
  <sequence>3</sequence>
  <fname>S.</fname>
  <lname>Ge</lname>
</author>
<affiliation affid="aff1">This is the second affiliation.</affiliation>
<affiliation affid="aff2">This is the second affiliation.</affiliation>
<affiliation affid="aff3">This is affiliation three.</affiliation>
</authors>

It would help if you posted the XML you are transforming.

I'm trying to made the following code work: ./footnote|//footnote[@id=./@fnref]

I want to select the child footnote element of author and any footnote that its id attribute matches the fnref attribute of the author.
 
In footnote[@id=./@fnref], is "." referring to author or to footnote? How do you refer author?

Thanks.

Peiyun


<xsl:template match="author">
    <!-- something here -->
	     <xsl:choose>
	     <xsl:when test="count(./footnote|//footnote[@id=./@fnref]) = 1">
	        <xsl:apply-templates select="./footnote|//footnote[@id=./@fnref]"/>
	     </xsl:when>
	 
	     <xsl:when test="count(./footnote|//footnote[@id=./@fnref]) > 1">
