xsl:sort does not work with nodeset parameters
----------------------------------------------
Key: XALANJ-2244
URL: http://issues.apache.org/jira/browse/XALANJ-2244
Project: XalanJ2
Type: Bug
Components: XSLTC
Environment: JDK 1.5.0_06
Reporter: Nicolas
i create some number elements within a variable, pass them to a function that
extract the maximum value, and i get an empty result.
this happens width jdk 1.5 default transformer, but not with Saxon transformer
or jdk 1.4.2 default transformer.
simple function to calculate the maximum value of some nodes passed as
parameter :
<xsl:template name="max">
<xsl:param name="nodes" select="/.."/>
<xsl:for-each select="$nodes">
<xsl:sort data-type="number" order="descending"/>
<xsl:if test="position() = 1">
<xsl:value-of select="number(.)"/>
</xsl:if>
</xsl:for-each>
</xsl:choose>
</xsl:template>
simple elements :
<xsl:variable name="foo">
<xsl:element name="bar">
<xsl:text>5</xsl:text>
</xsl:element>
<xsl:element name="bar">
<xsl:text>8</xsl:text>
</xsl:element>
<xsl:element name="bar">
<xsl:text>2</xsl:text>
</xsl:element>
</xsl:variable>
call the function :
<xsl:variable name="result">
<xsl:call-template name="max">
<xsl:with-param name="nodes" select="nodeset($foo)/bar"/>
</xsl:call-template>
</xsl:variable>
see the result :
<xsl:value-of select="$result" /> is empty
If i remove the <xsl:sort ...> line in the function, result is 5 (wich is
logic)
If i use the function inline, it works :
<xsl:variable name="result">
<xsl:for-each select="nodeset($foo)/bar">
<xsl:sort data-type="number" order="descending"/>
<xsl:if test="position() = 1">
<xsl:value-of select="number(.)"/>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:value-of select="$result" /> is 8
