Two ways to call XSLT extension 2003-04-17 - By Karsten Theis
Hi,
I'he done my first own XSTL extension function. It's a function with one
String parameter. It works fine if I call it this way:
...
<xsl:variable name="reflexionMatrix">
<xsl:call-template name="getReflexionMatrix">
<xsl:with-param>
<xsl:text>1 0 0 0 1 0 0 0 1</xsl:text>
</xsl:with-param>
</xsl:call-template>
</xsl:variable>
...
<xsl:template name="getReflexionMatrix">
<xsl:param name="matrix"/>
<xsl:value-of select="qmatrix:extractReflectionMatrix($matrix)" />
</xsl:template>
But it doen's work if I call it this way:
<xsl:variable name="MatrixRef">
<xsl:call-template name="MatrixRef">
<xsl:with-param>
<xsl:value-of select="concat('1, ' ', '0', ' ', '0', ' ', '0', ' ', '1',
' ', '0', ' ', '0', ' ', '0', ' ', '1')"/>
</xsl:with-param>
</xsl:call-template>
</xsl:variable>
I get the error:
(Location of error unknown)XSLT-Fehler
(javax.xml.transform.TransformerException
): java.lang.NullPointerException
... finished
In my understanding of XSLT, both ways to call the function are exactly the
same! But there must be a difference!
I'm using xalan-j_2_4_D1
the java-function is declared as follows:
public static String extractReflectionMatrix(String p0)
Thanks for your help,
Karsten
