Note: You are currently viewing documentation for Moodle 2.3. Up-to-date documentation for the latest stable version is available here: XHTML format.
The XHTML export format simply exports all the questions in the category as an XHTML form. In most cases the question answers are not included. It is intended as a basis for producing a set of questions to be used in some other web application and will almost certainly require further editing to be useful.
Each question is clearly placed in its own <div> tag. If you want to use this page as-is, you will need to at least edit the <form> tag at the start of the <body> section to provide a suitable action (e.g. a 'mailto').
