Re: xsl loop with variable

Hello,

Your Stylesheet is incorrect..It should actually not work  for the reason
that you have defined two variables of the same name within one template ,
which is an error.If you are using older version of XALAN then it would
probably work and this is a bug XALAN.

> I can't make "numMonth" variable update with the correct increment out of
the "if" tag, so that "Num months:" show me the correct value (until >now
only show '0', the original value).

In XSLT you can not update a variable. once you have assigned a value to
it,the variable has this value untill it goes out of scope.

 ><xsl:if test="not($lastMonth=substring(editionDate,4,2))">
 ><xsl:variable name="numMonth" select="$numMonth+1"/>
 ></xsl:if>
You cant access this variable outside the xsl:if .. it goes out of scope.
I guess what you want to do is..
for-each listObject/object,
If the given condition satisfies, then add 1 to the value of numMonth and
store it in a variable.
you may want to try the following to do what you want to do.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:template match="/">
  <xsl:variable name="numMonth" select="1"/>
  <xsl:variable name="lastMonth" select="00"/>
  <xsl:for-each select="listObject/object">
   <xsl:variable name="numMonth1">
    <xsl:if test="not($lastMonth=substring(editionDate,4,2))">
     <xsl:value-of select="$numMonth+position()"/>
    </xsl:if>
   </xsl:variable>
   <xsl:value-of select="$numMonth1"/>
   <xsl:variable name="lastMonth1" select="substring(editionDate,4,2)"/>
   <!--<xsl:value-of select="$lastMonth1"/> -->
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

If this is not what you want,please let us know  and some one in the list
would be able to help you.
