I've created a macro that lists all the files within a chosen media folder, using XSLT in 4.9.0

Each file can be downloaded using a href = "{./umbracoFile}"

Is there anyway I can add a button/link so that all files can be downloaded at once?
Would be nice if they could be zipped but not necessary (could just download multiple files).

<xsl:template match="/">
  <!--<p> <b>mediaFolder:</b> <xsl:value-of select="$mediafolder" /> </p>-->

  <xsl:if test="$mediafolder !=''">
    <xsl:variable name="files" select="umbraco.library:GetMedia($mediafolder, true())" />

    <!-- Uncomment this for DEBUG and view the HTML source of your page to see the XML snippet --> 
    <!--<xsl:copy-of select="$files" />-->

    <xsl:if test="$files != ''">
      <div class="download-container"> 
        <!-- For each XML node <node> where the nodeTypeAlias attribute = File -->
        <xsl:for-each select="$files/Folder/Download[@nodeTypeAlias = 'Folder']">
          <a href="{./umbracoFile}"> <xsl:value-of select="@nodeName" /> </a>
        </xsl:for-each>
      </div>
    </xsl:if>
  </xsl:if>
</xsl:template>
