Hello, i have created an Umbraco Form, and will be sending mail with xslt transformed mail. But how can i exclude empty fields which are not filled. My test example is just the default "sendXsltEmailSample.xslt" which right now just include all fields empty or not.

<?xml version="1.0" encoding="utf-8"?>

<h3>Intro</h3>
<p>
  Hello, this is a sample email using xslt to convert a record into a custom email
</p>

<h3>the fields</h3>
<ul>
  <xsl:for-each select="$records//fields/child::*">
    <li>
      <h4>
        Caption: <xsl:value-of select="./caption"/>
      </h4>
      <p>
        <xsl:value-of select=".//value"/>
      </p>
    </li>
  </xsl:for-each>
</ul>

<h3>The actual xml</h3>
<xsl:copy-of select="$records"/>
