XSLT lower-case using .NET

Question

i use the following XSLT by using XMLSpy:

<?xml version="1.0" encoding="UTF-16"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">
    <xsl:output method="xml" version="1.0" encoding="UTF-16" indent="yes"/>
        <xsl:template match="*">
        <xsl:element name="{lower-case(local-name())}">
            <xsl:apply-templates select="@*"/>
            <xsl:apply-templates select="* | text()"/>
        </xsl:element>
    </xsl:template>
    <xsl:template match="@*">
        <xsl:attribute name="{lower-case(local-name())}"><xsl:value-of select="."/></xsl:attribute>
    </xsl:template>
</xsl:stylesheet>

If i try to use it in my source (XslCompiledTransform) i get an exception telling me that the function 'lower-case()' is not part of the XSLT synthax.

So i changed the transformation a little bit:

fn:lower-case

Now my exception is that the script or external object prefixed by 'http://www.w3.org/2005/xpath-functions' can not be found. Whats the matter here? How can i fix it?

Regards

Answer 1

.NET does not implement XSLT 2.0/XPath 2.0.

In XPath 1.0 one can use the following expression, instead of lower-case():

translate(yourString, 
          'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 
          'abcdefghijklmnopqrstuvwxyz')
