Subject: [xsl] Help creating and calling xsl:functions
Hi all,
I'm having trouble getting even basic uses of xsl:function to work in my
browsers. I'm using this sample code, from
http://www.xml.com/lpt/a/2003/09/03/trxml.html:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:foo="http://whatever";>
<!-- Compare two strings ignoring case, returning same
values as compare(). -->
<xsl:function name="foo:compareCI">
<xsl:param name="string1"/>
<xsl:param name="string2"/>
<xsl:value-of
select="compare(upper-case($string1),upper-case($string2))"/>
</xsl:function>
<xsl:template match="/">
compareCI red,blue: <xsl:value-of select="foo:compareCI('red','blue')"/>
compareCI red,red: <xsl:value-of select="foo:compareCI('red','red')"/>
compareCI red,Red: <xsl:value-of select="foo:compareCI('red','Red')"/>
compareCI red,Yellow: <xsl:value-of
select="foo:compareCI('red','Yellow')"/>
</xsl:template>
</xsl:stylesheet>
I create a "dummy" XML document, using this stylesheet, as follows:
<?xml version="1.0" ?>
<?xml-stylesheet type="text/xsl" href="fn_test.xsl" ?>
<test_tag>Nothing to see here</test_tag>
When using Firefox 1.5.0.1, I get the following error when I try to open
the XML file in the browser:
Error during XSLT transformation: An unknown XPath extension
function was called.
When using IE 6.0, I get the following error:
Namespace 'http://whatever' does not contain any functions.
Any idea why I'm not getting function calls to work?
Thanks in advance,
Will
Neither IE nor Firefox support version XSLT 2.0.
One way to do this would be to transform using Saxon, either Java or .NET,
possibly on the server.
