RE: Sorting the complete xml file

I'm sure I've already answered this question.

<xsl:template match="*">
  <xsl:copy>
    <xsl:copy-of select="@*">
    <xsl:apply-templates select="*">
      <xsl:sort select="name()"/>
      <xsl:sort select="."/>
    </xsl:apply-templates>
  </xsl:copy>
</xsl:template>

will sort the element nodes at every level, first by name and then by
content. But it won't normalize the order of attributes and it won't handle
mixed content.

You are using sorting as a means to an end, and it might be better to
concentrate on your real requirement, which is comparison. I'm using XSLT
2.0 here because it makes life so much easier. XSLT 2.0 gives you a
deep-equal() function that does much of the job for you, but it's also quite
possible to code it yourself (if you want slightly different logic, for
example). For example, you can compare two sets of attribute nodes like
this:

<xsl:function name="compare-attributes" as="xs:boolean">
  <xsl:param name="element1" as="element()"/>
  <xsl:param name="element2" as="element()"/>
  <xsl:variable name="A1" select="$element1/@*"/>
  <xsl:variable name="A2" select="$element1/@*"/>
  <xsl:sequence select="count($a1) eq count($a2)
                        and every $a1 in $A1 satisfies
                              some $a2 in $A2 satisfies
                                (node-name($a1) eq node-name($a2)
                                   and
                                 string($a1) eq string($a2))"/>
</xsl:function>
