transformation in particular sequence

Question

I would like to know that is it possible to move xml element up or down in element tree.

The input xml.

<ROOT>
 <A1>A</A1>
 <B1>B</B1>
 <C1>C</C1>
 <D1>D</D1>
</ROOT>

The required output xml.

<ROOT>
 <A1>A</A1>
 <D1>D</D1>
 <B1>B</B1>
 <C1>C</C1>
</ROOT>

XSD Sequence Rule

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"      xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="ROOT">
 <xs:complexType>
  <xs:sequence>
    <xs:element type="xs:string" name="A1"/>
    <xs:element type="xs:string" name="D1"/>
    <xs:element type="xs:string" name="B1"/>
    <xs:element type="xs:string" name="C1"/>
  </xs:sequence>
  </xs:complexType>
  </xs:element>
  </xs:schema>

Can anyone provide me some XSLT example to do this such of thing? Thank you for any help in advance.

Martin Honnen help me to get answer from other post, hence just thought to share answer to help others but still I am wondering if there is any other way to do this - as in this approach if there is change in XSD tag sequence one has to change xsl sequence too.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

<xsl:output indent="yes"/>

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

<xsl:template match="ROOT">
<ROOT>
<xsl:apply-templates select="A1"/>
<xsl:apply-templates select="D1"/>
<xsl:apply-templates select="C1"/>
<xsl:apply-templates select="B1"/>
</ROOT>
</xsl:template> 

<xsl:template match="A1">
<a1>
    <xsl:apply-templates />
</a1>
</xsl:template>

 <xsl:template match="B1">
<b1>
    <xsl:apply-templates />
</b1>
</xsl:template>

 <xsl:template match="C1">
<c1>
    <xsl:apply-templates />
</c1>
</xsl:template>

<xsl:template match="D1">
<d1>
    <xsl:apply-templates />
</d1>
</xsl:template>

 </xsl:stylesheet>
