To get ORADictionary XML output for each code, you may append "?output=xml" parameter in the code URL.

For example, for the code ORA-00123 content, you may request http://oradictionary.appspot.com/code/ORA-00123?output=xml to get the XML format content.

The schema for the XML content showed as below:

<oradictionary>
	<prefix>ORA</prefix>
	<code>00123</code>
	<description>idle public server terminating</description>
	<cause>Too many idle servers were waiting on the common queue.</cause>
	<action>This error is used internally, no action is required.</action>
</oradictionary>
