xml and buffers

[Junod Antoine <toto@tots-ns.net>]

Hello gurus, 

I'm a bit into trouble wih buffers and xml parsing. Here is my problem:

I've got a .xhtml with the following lines:

     [...]
     <meta name="course_name" content="Génie Logiciel" />
     <meta name="date" content="23 décembre 2005" />
     [...]
     <title>Auction: document d'analyse</title>
     [...]

I'm trying to store the content of the meta tag in a buffer, one per
meta tag, (ie "Génie Logiciel" in buffer course_name, "23 décembre
2005" in buffer date) to use these buffers when I meet the title tag:

     \XMLifequalelse{meta}{name}{course_name}
          {\startbuffer[course_name]\XMLpar{meta}{content}{}\stopbuffer}{}
     \XMLifequalelse{meta}{name}{date}
          {\startbuffer[date]\XMLpar{meta}{content}{}\stopbuffer}{}
     \defineXMLenvironment [title] {\startstandardmakeup
                                    \getbuffer[course_name]
                                    \getbuffer[date]}{\stopstandardmakeup}

But it does not print anything else than the title.

Any idea?

Thanks a lot for you help!
