Hi Folks,
Thanks a lot for all your responses. Michael Kay has provided an alternative of
using position() function. What I am trying to do is display the category
heading only once if the article of that category is found.
Thanks again.
Vivek

Subject: [xsl] Retaining value of a Global variable
Hi,
I have a global variable defined at the top of my stylesheet. When I try to use
it subsequently it gets reinitialized. Here's the code.
<xsl:variable name="whead" select="'No'" />
<xsl:template match="/newsletter">
.
.
<xsl:apply-templates select="content/article" mode="proc_webcastheader"
/>.
</xsl:template>
<xsl:template match="article" mode="proc_webcastheader"> <xsl:variable
name="artclass" select="normalize-space(metadata/article-classification/.)" />
<xsl:if test="contains($artclass,'Biz-Webcast')">
<p><xsl:value-of disable-output-escaping="yes" select="$whead"/></p>
<IMG
src="http://www.sas.com/subscriptions/images/hdr_webcast.gif"></IMG>
<xsl:variable name="whead" select="'Yes'" />
<p><xsl:value-of disable-output-escaping="yes" select="$whead"/></p>
</xsl:if> </xsl:template>
In the second template when I print whead before the <img> it shows 'No' for
all articles even if I set it to 'Yes' after the <img>. Any clues on how to
retain the value of the variable?
Thanks
Vivek
