It's not an XSLT file, it's a stylesheet written in an obsolete Microsoft
language (often called WD-xsl) that was based on an early draft of XSLT,
with Microsoft additions and deletions.

Usually if a task is urgent and the user is a novice I reckon the best
advice I can give is "don't even attempt it, you will only make a mess of
it". However this one is fairly easy. I suspect you want to change the
element names to lower-case too? That's essentially a modified identity
stylesheet:

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  
  <xsl:template match="*">
    <xsl:element name="lower-case(name())" namespace="{namespace-uri()}">
      <xsl:apply-templates select="@* | node()"/>
    </xsl:element>
  </xsl:template>

  <xsl:template match="@*">
    <xsl:attribute name="lower-case(name())" namespace="{namespace-uri()}">
      <xsl:value-of select="."/>
    </xsl:element>
  </xsl:template>

</xsl:stylesheet>

That solution uses XSLT 2.0. If for some reason you have to use XSLT 1.0,
you can replace

lower-case(X)

by

translate(X, 'ABCDE....Z', 'abcde....z')
