By the way, you've fallen into the same trap I did when trying to learn
XSLT. You need to shift your mindset from functional programming.
In XSLT, <xsl:apply-templates /> is the same thing as using for-each and
is the preferred method.
And instead of using <xsl:choose><xsl:when/></xsl:choose>, create a
template match for each of the cases, as I did above.
This will allow the xsl processor to optimize the code and will allow
you to focus on specifically what to do when a certain element is
encountered, instead of trying to code the logic to drive the
transformation.
Thanks!
Angela

Subject: [xsl] Choose conditional by tag value
Dear XSL list:
I am new to this, and I've tried to figure out why this isn't working
using books and websites without any success. Please share your insight
with me!
I am styling XML that is produced by third party software. It gives a
list of events, and if there aren't any events, it gives a message in
the <title> tag that reads No Events Currently Scheduled. I want that
to look different than days with actual events. So:
<xsl:template match="/">
<xsl:choose>
<xsl:when test="[title='No Events Currently Scheduled']">
<p>No events scheduled</p>
</xsl:when>
<xsl:otherwise>
<xsl:for-each select="event/item">
<div class="xmlitem">
<h3>
<span class="xmlfeedtitle">
<a>
<xsl:attribute name="href">
<xsl:value-of select="link" />
</xsl:attribute>
<xsl:value-of select="title"
disable-output-escaping="yes"></xsl:value-of></a>
</span>
</h3>
<p class="xmlitemdate">
<xsl:value-of select="time"></xsl:value-of> at
<span class="xmlfeedlocation">
<xsl:value-of select="library"></xsl:value-of>
</span>
</p>
</div>
</xsl:for-each>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
And I have two XML samples to work with:
No events:
<event>
<item>
<title>No Events Currently Scheduled</title> <date/> <time/>
<description/> <location/> <library/> <link/> </item> </event>
Events:
<item>
<title>Basic PC (Personal Computers)</title> <date>Tuesday August 7th,
2007</date> <time>09:00 AM</time> <description>Want to learn how to use
personal computer? This free, one-hour basic computer training class is
an excellent place to start.
Gain experience using the mouse, keyboard and Microsoft Windows
operating system.</description> <location></location> <library>Corinth
Library</library>
<link>http://calendar.jocolibrary.org/evanced/lib/eventsignup.asp?ID=262
3
</link>
</item>
</event>
Can anyone please tell me what I am doing wrong? I thought it was the
spaces, but it's a string... right? Thank you for your help.
