Count the Element

Hi guys,

i'm using xslt 2.0 for the below task, I have a doubt for how to count the element (author) inside the <authors>tag and If my author element count is more than 5 need to add the text i.e (,et al. ) in the output xml.

Any one help me please.......

Input xml:

Code:

<authors>
<author>
<surname>Assink</surname> 
<given-name>EHM</given-name>
</author>
<author>
<surname>Assink</surname> 
<given-name>EHM</given-name>
</author>
<author>
<surname>Assink</surname> 
<given-name>EHM</given-name>
</author>
<author>
<surname>Assink</surname> 
<given-name>EHM</given-name>
</author>
<author>
<surname>Assink</surname> 
<given-name>EHM</given-name>
</author>
<author>
 <surname>Assink</surname> 
 <given-name>EHM</given-name>
 </author>

Output needed:

Code:

<authors>
<author>
<surname>Assink</surname> 
<given-name>EHM</given-name>
</author>
<author>
 <surname>Assink</surname> 
 <given-name>EHM</given-name>
 </author>
<author>
 <surname>Assink</surname> 
 <given-name>EHM</given-name>
 </author>
<author>
 <surname>Assink</surname> 
 <given-name>EHM</given-name>
 </author>
<author>
 <surname>Assink</surname> 
 <given-name>EHM</given-name>
 </author>
<author>
 <surname>Assink</surname> 
 <given-name>EHM</given-name>
 </author>, et al.

If the context node is the authors element, count(author) will tell you how many author children it has.

Try this:

Code:

<xsl:template match="authors">
<authors>
<xsl:if test="count(author) &gt; 5">
<xsl:copy-of select="author"></xsl:copy-of>
<xsl:text>, et al.</xsl:text>
</xsl:if>
</authors>
</xsl:template>

If the Input XML is having only 5 records with author element then the output will not come correctly. Use when instead of if.

Try this code.

<xsl:template match="authors">
<authors>
<xsl:choose>
<xsl:when test="count(author) > 5">
<xsl:copy-of select="author"></xsl:copy-of>
<xsl:text>, et al.</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="author"></xsl:copy-of>
</xsl:otherwise>
</xsl:choose>
</authors>
</xsl:template>
