Re: [xsl] How to count the distinct values where elements with missing c

Hi Roger,
    How about below mentioned solution, for your requirements.

XML document : provided XML document

XSLT stylesheet,

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                         version="3.0">

   <xsl:output method="text"/>

   <xsl:template match="/">
      <xsl:value-of select="count(distinct-values(test/row/transition)) +
                                                        (if (some $row in
test/row satisfies not($row/transition)) then 1 else 0)"/>
   </xsl:template>

</xsl:stylesheet>
