Show "all possible" extended data fields in balloon

Question

Background: Alright so I am working on an application that uses SharpKML to produce a number of Placemarks that each have properties associated with it. I want to show these properties as custom data elements within the popup balloon.

Problem: I cannot seem to be able to set my balloon style to show all of the extended data elements in a table regardless of how many there are or their name.

Please if you can help with this.

Cheers.

Edit: Added the KML code that is produced.

<Style id="cim-default-conductors">
  <LabelStyle>
    <color>ff7814b4</color>
    <colorMode>normal</colorMode>
    <scale>1</scale>
  </LabelStyle>
  <LineStyle>
    <color>ff7814b4</color>
    <colorMode>normal</colorMode>
    <width>3</width>
  </LineStyle>
  <BalloonStyle>
    <bgColor>ffffffff</bgColor>
    <textColor>ff000000</textColor>
    <text><![CDATA[<b>$[name]</b><br/>Conductor Spacing: $[amst:phase_spacing_summary]<br/>Description: $[description]<br/>]]></text>
    <displayMode>default</displayMode>
  </BalloonStyle>
</Style>
