How to display changing data in XUL

Question

Hi, I'm trying to build a firefox extension which can get rss feeds and display them in a popup panel. But I'm not aware about how to display feeds in a panel(I know how to display static text).Because the feed is varying all the time. Any help regarding this matter will be appreciated. Thanks in advance.

Answer 1

How about using setInterval to call a function that redraws the panel at the time interval you specify?

Answer 2

You can create DOM elements inside a XUL popup panel using JavaScript, but you have to remember that the panel requires the XHTML namespace:

<panel id="your-id" noautohide="true" xmlns:html="http://www.w3.org/1999/xhtml"&gt;

and instead of using:

document.createElement("p"); //for example

you would need to use:

document.createElementNS("http://www.w3.org/1999/xhtml","html:p");

You can get the popup reference by id and just create and append elements as you need them. Then the following might help:
