&lt;p&gt;You can try indexing your CDT value.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;ex: ri!cdt.&lt;strong&gt;externalDocument --------&amp;gt; index(ri!cdt, &amp;quot;externalDocument&amp;quot;, &amp;quot;&amp;quot;)&lt;/strong&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
