emacs+WordPress: xml attributes for Simile Timeline Project

[celano]

Hello,

I know emacs works with WordPress to send articles.

On my WordPress website, I installed the WPSimileTimeline plugin, part 
of the Simile Widgets Project (http://simile-widgets.org/timeline/).
So, when I create an article inside WordPress, I give chronological 
informations about the article, which then appear in my timeline.

Is it possible, from emacs, to give these chronological informations in 
a simple way? I mean: without to many codes?

I'm not a geek, so please explain easily ;-)

Thanks
Celano
