Daniel FrechetteSubject: Reference to var 'xxx' must evaluate to a node list
Author: Daniel Frechette

ello,

I get the error message "Reference to variable or parameter 'dayNames' must evaluate to a node list" when I execute the following transformation using any MSXSL processor. The error occurs on the last line. Does anyone know what this error means? Is there a better way of doing this?

Thank you.
Daniel

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:str="http://exslt.org/strings" extension-element-prefixes="str">

<xsl:import href="str.tokenize.inc.xsl"/>

<xsl:variable name="dayNames">
<xsl:call-template name="str:tokenize">
<xsl:with-param name="string" select="'Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday'" />
<xsl:with-param name="delimiters" select="'|'" />
</xsl:call-template>
</xsl:variable>

<xsl:variable name="sunday" select="$dayNames/token[1]/text()"/>

</xsl:stylesheet>

Daniel,

1) Please don't use the Refresh or Back buttons on your browser, it causes your messages to be posted twice. If you want to refresh, just click anywhere in the "Conferences" side bar. :)

2) Your xslt looks like it should work, but there is a little trap in XSLT 1.0. XSLT 1.0 doesn't understand that a variable ($dayNames) might contain a node set, so you have to force it:

In the top of your xslt, add this namespace:
xmlns:msxsl="urn:schemas-microsoft-com:xslt"

Then, change this line:
<xsl:variable name="sunday" select="$dayNames/token[1]/text()"/>
to this
<xsl:variable name="sunday" select="msxsl:node-set($dayNames)/token[1]/text()"/>

By the way, you probably know this, but just in case: You wont see any output from this program unless you add a <xsl:value-of ... or something.

Good luck.
Clyde

Thank you Clyde.

To make my code cross-browser compatible I will have to test the processor's vendor property before I use "msxsl:node-set(...)".

Thank you again.

Here is the solution for those interested.

=== XML file ===
Any valid XML file will do

=== XSL file ===
<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:str="http://exslt.org/strings"
extension-element-prefixes="msxsl str">

<xsl:import href="str.tokenize.inc.xsl"/>

<xsl:variable name="dayNames">
<xsl:call-template name="str:tokenize">
<xsl:with-param name="string" select="'Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday'" />
<xsl:with-param name="delimiters" select="'|'" />
</xsl:call-template>
</xsl:variable>

<xsl:template name="dayName">
<xsl:param name="pDayNo" select="1"/>
<xsl:choose>
<xsl:when test="function-available('msxsl:node-set')">
<xsl:variable name="ns" select="msxsl:node-set($dayNames)"/>
<xsl:value-of select="$ns/token[$pDayNo]/text()"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$dayNames/token[$pDayNo]/text()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

<xsl:template match="/">
<xsl:call-template name="dayName"/>
</xsl:template>

</xsl:stylesheet>

=== Output ===
Sunday
