click > send string to xml > get specific node from xml > parse it > load it on modal window

I'm taking way too long to solve this. I'm about to give up, but I figured I'd give you sorcerers a try.

I have a xml file. I want to click a link with a string, use that string to match and select a specific xml node [name], parse it to html, and load it on a modal window (fancybox):

This is how my xml file looks like:

<speakers>
<speaker>
<name>Cátia Miriam Costa</name>
<bio>Es Licenciada en Relaciones Internacionales, Máster en Estudios Africanos, doctoranda en Literatura africana y co-directora de la revista Ifriqya: lletres africanes.</bio>
</speaker>
...

In layman terms:

Click "Cátia Miriam Costa", load modal window with Catia's name and bio.

Thank you,

Ana Rita
