 <p>Use the <codeph>PlanExporter</codeph> tool to export query plan data
for
-further analysis. The query plan data can be exported in a variety of formats.
-The base format for exported query plan data is XML. Query plan data can also
-be exported in HTML format, which helps you view graphically 
-the execution plans of complex queries you have executed. By using this tool
-you can avoid querying <codeph>XPLAIN style tables</codeph> to get a 
-basic idea of the query plan followed by the <codeph>Optimizer</codeph>.
-You can specify other query plan export formats by specifying an appropriate
+further analysis. The query plan data can be exported in a variety of formats:
+</p>
+<ul>
+<li>XML, the base format for exported query plan data</li>
+<li>HTML, which helps you view graphically the execution plans of complex
+queries you have executed</li>
+</ul>
+<p>By using this tool, you can avoid querying XPLAIN style tables to get a 
+basic idea of the query plan followed by the optimizer.</p>
+<p>You can specify other query plan export formats by specifying an appropriate
 XSL stylesheet to transform the query plan data, or you can export the
 query plan data as XML, then reformat as appropriate using any external
-XML-aware tool of your choice.
