<root>
  <param1>blah</param1>
  <param2>blah</param2>
  <param3>blah</param3>
</root>

<xsl:template match="root">
  <xsl:variable name="query-string">
    <xsl:text>?</xsl:text>
    <xsl:for-each select="*">
      <xsl:value-of select="name()"/>

      <xsl:if test="position()!=last()">
        <xsl:text>&amp;</xsl:text>
      </xsl:if>
    </xsl:for-each>

  <xsl:text>variable $query-string: </xsl:text>
  <xsl:value-of select="$query-string"/>
