how to get images from external xml and view it on my app

i want to show images from external url 开发者_开发技巧listed in external xml ("similar" to picasa API).

from where i need to start, there is an app sample like this, do i can read is source?

• Start from seeing DOM and SAX parser for parsing XML in android
• Here is a nice code for SAX parser:
  http://www.anddev.org/parsing_xml_from_the_net_-_using_the_saxparser-t353.html
• Then see sample codes to fetch remote images in image view

Hope it will give you an idea
