XML : XLST Identity Template specific elements, exclude everything else

Using the below XML how would I extract only the Address details into a CSV format?

I believe I need to have a style sheet based on the Identity template, though the examples I found are simple and state to the list the elements you want to exclude. Is there a short way to exclude everything except Address and AddressLine?

I am using .NET to process the XLST transformation. The stylesheet I have come up with so far doesn't return anything.

  <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">    <xsl:output method="text" encoding="utf-8" />    <xsl:strip-space elements="*"/>      <xsl:param name="delim" select="','" />    <xsl:param name="quote" select="'&quot;'" />    <xsl:param name="break" select="'&#xa;'" />      <xsl:template match="node()| @*">      <xsl:copy>        <xsl:apply-templates select="node()| @*"/>      </xsl:copy>    </xsl:template>      <xsl:template match="AddressLine" priority="9">      <xsl:value-of select="concat($quote, ., $quote, $delim)"/>    </xsl:template>      <xsl:template match="*" priority="0" />  </xsl:stylesheet>
