I have this xml:
...
And I want to transform it to this one:
(The difference is that all the ccc elements, and it's children are removed
from the location where they are and putted below the root element)

T:\ftemp>type pedro.xml
<root>
            <aaa>
                        <bbb/>
                        <ccc/>
                        <bbb/>
            </aaa>
            <aaa>
                        <ccc>
                                   <abc>test</abc>
                        </ccc>
                        <bbb/>
                        <bbb/>
            </aaa>
</root>

T:\ftemp>type pedro.xsl
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="root">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
    <xsl:copy-of select="//ccc"/><!--collect all ccc elements-->
  </xsl:copy>
</xsl:template>

<xsl:template match="@*|node()"><!--identity for all other nodes-->
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

<!--this cleans up the output when using indent="yes"-->
<xsl:template match="text()[not(normalize-space())]"/>

</xsl:stylesheet>
T:\ftemp>saxon pedro.xml pedro.xsl
<?xml version="1.0" encoding="utf-8"?>
<root>
   <aaa>
      <bbb/>
      <bbb/>
   </aaa>
   <aaa>
      <bbb/>
      <bbb/>
   </aaa>
   <ccc/>
   <ccc>

   </ccc>
</root>
T:\ftemp>
