How can I get image's url that have been inserted into CkEditor in my asp file?

Hi Folks:

 Is there any way I can extract url of images that have been inserted into CkEditor? After I used CKFinder file browser to pick one image and click ok. Image was inserted into CkEditor. I Open up html file, and no url display their, I can get whole bunch of html within editor using Request.Form("ID"), but using ASP is very hard to parse html on server side. How can I do that? Any advice is appreciated.
