How to get output XML same as input XML?

Canonical Identity Transformation, right out of the XSLT spec:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

<xsl:stylesheet>

This does not guarantee that the output document exactly matches the input;
details not considered meaningful to XML or to XSLT's data model (eg, the
order of attributes) may be changed. But that falls in the category of "a
difference which makes no difference is no difference" -- if you don't
consider those alterations acceptable, don't put the document through
generic XML-based processing.
