Well, you could define a key

  <xsl:key name="id" match="knowledge-object" use="@id" />

and then just recursively go through knowledge-object and always retrieving their sub-topics. In your stylesheet you tried to use xsl:for-each, but you really need xsl:apply-templates to make the processing recursive. The only problem you have is how to identify the topic root knowledge-object to start the processing, but since the example data is incomplete, it's hard to tell what will indicated root topics.
