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').
