Subject: Re: [xsl] Maths functions in a stylesheet? From: Norman Barker <normanb@xxxxxxxxxxxxx> Date: Fri, 25 Feb 2005 17:14:34 +0000 |
If any XSLT gurus could help with this...Hi Derek,
I have a "maths functions" stylesheet, adapted from another source -
<?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan="http://xml.apache.org/xalan";
xmlns:maths="http://www.mydomain.com/maths";
extension-element-prefixes="maths"
version="1.0">
<xalan:component prefix="maths" elements="rules" functions="sine cosine
abs pi">
<xalan:script lang="javascript"> function sine(thisValue) {
return Math.sin(thisValue);
}
function cosine(thisValue) {
return Math.cos(thisValue);
}
function abs(thisValue) {
return Math.abs(thisValue);
} function pi() {
return 3.141592653589790;
} </xalan:script>
</xalan:component>
</xsl:stylesheet>
Called like this:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan="http://xml.apache.org/xalan";
xmlns:maths="http://www.mydomain.com/maths";
extension-element-prefixes="maths"> >
<xsl:include href="functions.xsl"/> <xsl:template match="/">
<xsl:variable name="foo" select="maths:pi()" />
</xsl:template>
</xsl:stylesheet>
I get :
An Error Occurred java.lang.RuntimeException: Unknown error in XPath. cause: java.lang.RuntimeException: Unknown error in XPath.
when running this with Cocoon 2.1.5 (withe default build with Xalan).
Thanks Derek
<xsl:template match="value"> <xsl:value-of select="math:cos(.)"/> </xsl:template> </xsl:stylesheet>
