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
