 At 02:40 PM 12/19/01, you wrote: I am trying to display a date. I need to display the "Original Date" if it is returned. Getting the value of the node will return the value if the node exists, but nothing if it does not. If a Record with Name = ORIGINAL does not exist or the record with Name = ORIGINAL exists but a date for that record does not, I need to display the "Copy Date" (Name = COPY). The second case subsumes the first (if the ORIGINAL record does not exist, neither will it have a date), so we need to test only if there is (not) a date. The template below does this, dropping the ORIGINAL date into a variable (a node-set that either holds the date, or is empty) to make things a bit clearer. <xsl:template match="RecordSet">
<xsl:variable name="originalDate"
select="Record/Name[.='ORIGINAL']/RecordHistorySet/RecordHistroy/Date"/>
<!-- bind the node to the variable --><!-- we want its value (which is nothing if it doesn't exist) --> <xsl:value-of select="$originalDate"/> <!-- if it does not exist, we get the other value -->
<xsl:if test="not($originalDate)">
<xsl:value-of
select="Record/Name[.='COPY']/RecordHistorySet/RecordHistroy/Date"/>
</xsl:if></xsl:template> Does that help? A node-set tests as "true" if there is a node in the node-set, "false" if not.
