RE: [xsl] problem with xsl:if test statement

I'm rather confused by this question/example code.

Given the code you've sent us, it *doesn't* produce two links. The
for-each works once for each Fruits node, and if it matches the country
and the fruit, produces one link, even if there are two
<Type>Apples</Type> nodes.

Perhaps the answer to the more general question is to use count()? As
in,

	<xsl:for-each select="Products">
		<xsl:if test="count(Fruits[Type='Apples']) &gt; 0 ">
		there is at least one 'Apples' node in the
		Product node for <xsl:value-of select="Fruits/Country"/>
		</xsl:if>
	</xsl:for-each>

By the way, there are quite a few mistakes in your code and it doesn't
run without fixing them. I suspect you didn't send us the code you're
actually working on?

Subject: [xsl] problem with xsl:if test statement

Hello,

I'm new to xml and xsl. I need to generate one link if my query finds
one or more records in my XML document. But I if I use "for each
statement", the link will repeat again and again depending on how many
records satisfy my query. E.g., if 2 records satisfy my query, the link
will repeat twice like this:

For apples, click here
For apples, click here

How can I generate only one link if my query finds more than one
records?

XSL:
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";;>

<xsl:param name="Country" select="Mexico" ></xsl:param>
<xsl:template match="/">
<html>
<body>
<h2>Types of Fruits</h2>
<xsl:for-each select="Products/Fruits">
<xsl:if test="Country = $Country and Type = 'Apples'">
<a>
<xsl:attribute name="href">
fruits.aspx?moi=<xsl:value-of select="$Country"/>
</xsl:attribute>
For apples, click here
</a>
<br />
</xsl:if>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

XML:
<Products>
<Fruits>
<Country>Mexico</Country>
<Tpye>Apples</Type>
<Tpye>Bananas</Type>
</Fruits>
<Fruits>
<Country>Brazil</Country>
<Tpye>Oranges</Type>
<Tpye>Apples</Type>
</Fruits>
<Fruits>
<Country>Peru</Country>
<Tpye>Bananas</Type>
<Tpye>Oranges</Type>
</Fruits>
</Products>

Any help would be greatly appreciated!
