I have a command contained with a message and body that need to be duplicated. Like so:

<message>
 <body>
  <command name="1"/>
  <command name="2"/>
 </body>
</message>

What I would like is:

 <message>
 <body>
  <command name="1"/>
 </body>
</message>

<message>
 <body>
   <command name="2"/>
 </body>
</message>

I’m using the following:

<?xml version="1.0" encoding="UTF-8"?>
<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-8" indent="yes"/>
<xsl:template match="/">
    <xsl:variable name="items" select="/message/body/*"/>
    <xsl:for-each select="$items">
        <xsl:result-document href="section{position()}.xml">
            <xsl:copy-of select="../../.[position()]"/>
        </xsl:result-document>
    </xsl:for-each>
</xsl:template>

A few clarifications: the name attribute is not a position attribute so it can vary. The command name is not known and can vary. Commands are nodes themselves and can contain elements.

Based on Dabbler’s code I was able to produce this which successfully parses the following:

<message>
<body>
 <commandA num="1"/>
 <commandB num="5"/>
 <commandC num="25">
    <subCommandT />
 </commandC>
</body>
</message>

into 

<message>
 <body>
  <commandA num="1"/>
 </body> 
</message>

<message>
 <body>
  <commandB num="5"/>
 </body>
</message>

<message>
<body>
<commandC num="25">
      <subCommandT />
 </commandC>
</body>
</message>

Here is the code:

<?xml version="1.0" encoding="UTF-8"?>
<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-8" indent="yes"/>
<xsl:template match="/">
    <xsl:for-each select="/message/body/*">
        <xsl:apply-templates select="/*">
            <xsl:with-param name="CmdId" select="generate-id(.)" tunnel="yes"/>
            <xsl:with-param name="CmdPosition" select="position()" tunnel="yes"/>
        </xsl:apply-templates>
    </xsl:for-each>
</xsl:template>
<xsl:template match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>
<xsl:template match="message">
    <xsl:param name="CmdId" as="xs:string" tunnel="yes"/>
    <xsl:param name="CmdPosition" as="xs:integer" tunnel="yes"/>
    <xsl:result-document href="section{$CmdPosition}.xml">
        <xsl:copy>
            <xsl:apply-templates/>
        </xsl:copy>
    </xsl:result-document>
</xsl:template>
<xsl:template match="body/*">
    <xsl:param name="CmdId" as="xs:string" tunnel="yes"/>
    <xsl:if test="generate-id(.) = $CmdId">
        <xsl:copy-of select="."/>
    </xsl:if>
</xsl:template>

Thank you Dabbler!

Here is a sample of the original command:

<?xml version="1.0" encoding="UTF-8"?>
<tst:Message xmlns:tst="http://www.someschema.com/v1.4" xmlns:pc="http://www.someotherschema.com/v1.5">
<tst:Body tst:hostId="1" tst:machineId="77.D2" tst:dateTimeSent="2012-07-11T15:30:46">
    <tst:commandOption tst:deviceId="1" tst:dateTime="2012-07-11T15:30:46" tst:commandId="1" tst:sessionType="response" tst:sessionId="28" >
        <tst:commandOptionAck tst:transactionId="12" tst:configurationId="3148"/>
    </tst:commandOption>
    <tst:commandOption tst:deviceId="1" tst:dateTime="2012-07-11T15:30:48" tst:commandId="2" tst:sessionType="response" tst:sessionId="29" >
        <tst:commandOptionAck tst:transactionId="13" tst:configurationId="3149"/>
    </tst:commandOption>
    <tst:commandOption tst:deviceId="1" tst:dateTime="2012-07-11T15:30:50" tst:commandId="3" tst:sessionType="response" tst:sessionId="30" >
        <tst:commandOptionAck tst:transactionId="14" />
    </tst:commandOption>
    <pc:pContext pc:deviceId="1" pc:dateTime="2012-07-11T15:24:17" pc:commandId="4" pc:sessionId="47146">
        <pc:Exit pc:transactionId="3116380"/>
    </pc:pContext>
</tst:Body>

    There may be a better way, but this works:

    <?xml version="1.0" encoding="UTF-8"?>
<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-8" indent="yes"/>

   <xsl:template match="/">
      <xsl:for-each select="/message/body/*">
         <xsl:apply-templates select="/*">
            <xsl:with-param name="CmdNum" select="position()" tunnel="yes"/>
         </xsl:apply-templates>
      </xsl:for-each>
   </xsl:template>

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

   <xsl:template match="message">
      <xsl:param name="CmdNum" as="xs:integer" tunnel="yes"/>

      <xsl:result-document href="section{$CmdNum}.xml">
         <xsl:copy>
            <xsl:apply-templates/>
         </xsl:copy>
      </xsl:result-document>
   </xsl:template>

   <xsl:template match="command">
      <xsl:param name="CmdNum" as="xs:integer" tunnel="yes"/>

      <xsl:if test="@name = $CmdNum">
         <xsl:copy-of select="."/>
      </xsl:if>
   </xsl:template>
</xsl:stylesheet>

    The problem with the code as you have it is that the filter is applied to the message element instead of the commandelement.
