The easiest way to convert XML to XML or to HTML is to use XSL stylesheets. You simply process the XML-file with any program that can process stylesheets (browsers can, and xsltproc (*nix and Mac) and XMLSpy (Windows).

For example, the following is a stylesheet that does some conversion:

<?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="html"/>
      <!-- process the root node -->
      <xsl:template match="/">
            <ul>
                  <!-- now, process the nodes for /statistics/beforearrival/senderblacklist and /statistics/beforearrival/senderwhitelist -->
                  <xsl:apply-templates select ="/statistics/beforearrival/senderblacklist"/>
                  <xsl:apply-templates select ="/statistics/beforearrival/senderwhitelist"/>
            </ul>
      </xsl:template>
      <!-- processing instruction for /statistics/beforearrival/senderblacklist -->
      <xsl:template match="/statistics/beforearrival/senderblacklist">
            <li>The sender blacklist availability is <b>"<xsl:value-of select="available"/>"</b>. There were <xsl:value-of select="tests"/> tests performed, with <xsl:value-of select="hits"/> hits.</li>
      </xsl:template>
      <!-- processing instruction for /statistics/beforearrival/senderwhitelist -->
      <xsl:template match="/statistics/beforearrival/senderwhitelist">
            <li>The sender whitelist availability is <b>"<xsl:value-of select="available"/>"</b>. There were <xsl:value-of select="tests"/> tests performed, with <xsl:value-of select="hits"/> hits.</li>
      </xsl:template>
</xsl:stylesheet>

When I run this through my stylesheet processor with the file you uploaded:

powerbook:~/Desktop/Safari Downloaded Files miep$ xsltproc stats.xsl stats.xml
<ul>
<li>The sender blacklist availability is <b>"No"</b>. There were 0 tests performed, with 0 hits.</li>
<li>The sender whitelist availability is <b>"Yes"</b>. There were 120786 tests performed, with 935 hits.</li>
</ul>


Voila!
