That's not quite the same as JavaScript, now is it? VBScript is not
supported in .NET, but VB, C#, JScript, and JavaScript are [1]. I
imagine that, if you installed J#, that it would be supported as well.
Here is a JavaScript example that works:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:tns="urn:thisnamespace:tns"
exclude-result-prefixes="tns msxsl">
<msxsl:script language="JavaScript" implements-prefix="tns">
function GetString()
{
return('foo');
}
</msxsl:script>
<xsl:template match="/">
<xsl:for-each select="root/child">
<xsl:value-of select="tns:GetString()"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Change the language attribute of the msxsl:script element to "VB"
instead, and now this example works (note, though, that
VBScript-specific functions and syntax might not be supported in VB.NET
[1]):
<msxsl:script language="vb" implements-prefix="tns">
function GetString()
GetString = "foo"
end function
</msxsl:script>
The really cool part about .NET is that you can also use inline C# as
well as JavaScript or VB.NET. Although, I would use an extension object
with the XsltArgumentList class instead, but this example shows that it
is possible:
<msxsl:script language="C#" implements-prefix="tns">
string GetString()
{
return("foo");
}
</msxsl:script>
