I'd say, use the right tool, which is XSLT:

          \,,,/
          (o o)
------oOOo-(_)-oOOo------
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output method="text" />
  <xsl:strip-space elements="*"/>

  <xsl:template match="text()">
    <xsl:value-of select="concat( normalize-space(), '&#10;' )"/>
  </xsl:template>

  <xsl:template match="*">
    <xsl:value-of select="concat( '# Element ', name(), ':&#10;' )"/>
    <xsl:apply-templates/>
  </xsl:template>

</xsl:stylesheet>
-------------------------

Call it as follows:

  xsltproc milu.xsl your.xml

This should give you approximately the output you want.
