Hi,
Here is a possible solution, create a variabe to record the result of
"for-each" statement and test the length of the variable. It might not be
the perfect one. but it can get the desired result.
<xsl:transform xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
version='1.0'
xmlns:lang='en'
<xsl:template match="/">
<xsl:variable name="noFurry">
<xsl:for-each select="//animal">
<xsl:if test="furry = 'true'">
<xsl:value-of select="type"/><br/>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:if test="string-length($noFurry) = 0">
<xsl:message>None are furry</xsl:message>
</xsl:if>
</xsl:template>
</xsl:transform>

Subject: [xsl] Do something if no items in for-each meet criteria
I'm trying to
1) go through a set of nodes
2) if any matches my criteria, display it
3) if NONE matches my criteria, display a message like "None"
For example, imagine this xml listing some animals:
<animal>
<type>snake</type>
<furry>false</furry>
</animal>
<animal>
<type>fish</type>
<furry>false</furry>
</animal>
and this XSL that lists all the ones with fur:
The following animals are furry:<br/>
<xsl:for-each select="animal">
<xsl:if test="furry = 'true'">
<xsl:value-of select="type"/><br/>
</xsl:if>
</xsl:for-each>
[if no animals were furry, print "None are furry"] <---how can I do this?
Any way I can accomplish what I'm trying to do on the last line above?
Thanks.
