The value isn't the textnode's data.
It'smore likely to be the "val" attribute of the span itself.

 

Anyway, I'm pretty used to deal with complex javascript and DOM exploration but unless there is no built in way to do what I want to do, I'd like to avoid using a direct approach and write all off again if someday the DOM curesoft construct changes.

 

So, is there any built in (a interface) to do it or do I have to reverse engeneer your (x)hmlt markut and javascript ?
