问题 I came across this JavaScript intricacy and was struggling to find the difference. Its about JavaScript namespaces.

问题 When rendering XHTML with lxml, everything is fine, unless you happen to use Firefox, which seems unable to deal with namespace-prefixed XHTML elements and javascript. While Opera is able to execute the javascript (this applies to both jQuery and MathJax) fine, no matter whether the XHTML namespace has a prefix ( h: in my case) or not, in Firefox the scripts will abort with weird errors ( this.head is undefined in the case of MathJax).
