How to put < > brackets inside an XML element value?

If I have a <file> </file> element in an XML file and I want to insert a filename of the form PED<yyMMdd>232, how do I insert the < and > brackets as an element value inside the <file> tag?

I use JCreator to edit the xml file and it treats <yyMMdd> as a seperate element instead of being part of the filename.

Have you tried the HTML entities ( &lt; or &gt; )? Have you tried using CDATA?
