Re: double condition syntax

Hi Jeni,

Many thanks for that. I put in the expression and got
the second condition to work correctly for one
variable, but it seems not to work on the other.

Here's an xml snippet

------------------------------------------
<LOG>
   <DIRECT>
      <LOCATION_ID> 24 </LOCATION_ID>
      <TARGET_CHARACTER_LOCATION_ID> 2799
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE> hello </MESSAGE>
   </DIRECT>
   <DIRECT>
      <LOCATION_ID> 24488 </LOCATION_ID>
      <TARGET_CHARACTER_LOCATION_ID> 2455
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE> hello </MESSAGE>
   </DIRECT>
   <DIRECT>
      <LOCATION_ID> 23388 </LOCATION_ID>
      <TARGET_CHARACTER_LOCATION_ID> 266
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE> hello </MESSAGE>
   </DIRECT>
   <DIRECT>
      <LOCATION_ID> 293 </LOCATION_ID>
      <TARGET_CHARACTER_LOCATION_ID> 293
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE> no </MESSAGE>
   </DIRECT>
   <DIRECT>
      <LOCATION_ID> 31132 </LOCATION_ID>
      <TARGET_CHARACTER_LOCATION_ID> 31132
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE> no </MESSAGE>
   </DIRECT>
   <DIRECT>
      <LOCATION_ID> 24488 </LOCATION_ID>
      <TARGET_CHARACTER_LOCATION_ID> 24488
</TARGET_CHARACTER_LOCATION_ID>
      <MESSAGE> no </MESSAGE>
   </DIRECT>
 </LOG>

-----------------------------------------------
3 different locations all duplicate messages and 3 the
same locations with duplicate messages.

Here's my new stylesheet

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output method="text"/>
  
  <xsl:variable name="vTotalSent"
                  select="count(LOG/*/MESSAGE)"/>
  
  <xsl:variable name="vNumNotSame"
    select="count(LOG/*[number(LOCATION_ID) !=
                       
number(TARGET_CHARACTER_LOCATION_ID) and
                       
preceding-sibling::*[1]/MESSAGE !=
                        MESSAGE])"/>
                        
  <xsl:variable name="vNumSame"
    select="count(LOG/*[number(LOCATION_ID) =
                       
number(TARGET_CHARACTER_LOCATION_ID) and
                       
preceding-sibling::*[1]/MESSAGE !=
                        MESSAGE])"/>

   
   <xsl:template match="/">
   
   
   <xsl:text> The total number of messages sent was:
</xsl:text>
   <xsl:value-of select="$vTotalSent"/>
 
   
   <xsl:text> The total number of messages sent to a
different location was </xsl:text>
   <xsl:value-of select="$vNumNotSame"/>
  

   <xsl:text> The total number of messages sent to the
same location was </xsl:text>
   <xsl:value-of select="$vNumSame"/>

   
</xsl:template>

</xsl:stylesheet>
-------------------------------------------

And my output is:

The total number of messages sent was: 6 The total
number of messages sent to a different location was 0
The total number of messages sent to the same location
was 1

--------------------------------

So it correctly removed the duplicates from messages
sent to the same location, but counted 0 for the first
three different locations, instead of 1.

It must be something simple, but I can't see the
error.

Kind Regards

Marina
