Re: collapsing consecutive elements

How would you reverse this process?

t:\ftemp>type saverio.xml
<?xml version="1.0" encoding="utf-8"?>
<db>
   <a_b_c>
      <d/>
      <e/>
   </a_b_c>

   <f_g_h>
      <i/>
      <j/>
   </f_g_h>
</db>

t:\ftemp>type saverio.xsl
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="*" name="continue">
  <xsl:param name="name" select="name(.)"/>
  <xsl:choose>
    <xsl:when test="contains($name,'_')">
      <xsl:element name="{substring-before($name,'_')}">
        <xsl:call-template name="continue">
          <xsl:with-param name="name"
                          select="substring-after($name,'_')"/>
        </xsl:call-template>
      </xsl:element>
    </xsl:when>
    <xsl:otherwise>
      <xsl:element name="{$name}">
        <xsl:apply-templates/>
      </xsl:element>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

t:\ftemp>xt saverio.xml saverio.xsl
<?xml version="1.0" encoding="utf-8"?>
<db>
   <a><b><c>
      <d/>
      <e/>
   </c></b></a>

   <f><g><h>
      <i/>
      <j/>
   </h></g></f>
</db>
t:\ftemp>rem Done!
