A loop based on specified count

[kennethe]

I have this structure:

<data>
   <tot_num_in_list>1</tot_num_in_list>
   <person_info>
      <name/>
      <address/>
      <phone/>
   </person_info>
</data>

Inside the data-element there is 100 person_info-elements (I just wrote one for making it shorter to write). The tot_num_in_list-element contains the number of person_info-elements that is returned from the database with content. So, in this case I get in return from the database one person_info-element that contains a name, address and a phonenumber, and I also get 99 empty.

How do I exctract these data's based on the tot_num_in_list-element? Instead of looping through a 100 elements, I just want to go through the first 'n' elements based on the tot_num_in_list-element.

How can I achieve this?

If you want to use an xsl:for-each loop :

<xsl:template match="data">
  <xsl:variable name="tot" select="tot_num_in_list"/>
  <xsl:for-each select="person-info[position() &lt;= $tot]">
     ...
  </xsl:for-each>
</xsl:template>

If you want to use templates :

<xsl:template match="data">
  <xsl:variable name="tot" select="tot_num_in_list"/>
  <xsl:apply-templates select="person-info[position() &lt;= $tot]"/>
</xsl:template>
