How can I Pick the detail Report of DHL against a Track number in my site to Display?

I need a help.
In DHL, when we enter a track number (ex. 3086018456 ) in the textfield in http://www.dhl.com.bd/publish/bd/en/eshipping/track.high.html page and click Submit button, it shows Detail Report of shipment in tabular format in the next page (http://www.dhl.com.bd/publish/bd/en/eshipping/track.high.html?pageToInclude=RESULTS&type=trackindex&brand=DHL&AWB=3086018456). If I change the 3086018456 to 3086018434 in the URL of this page it shows detail against this number. OK.
Now, I have a page in my own site which has a textfield named TrackField. I want to enter the number 3086018456(I entered this number in DHL's Track field) in this field and I want to get the full report what I get in DHL's Result's page in my next page.

I have been already informed that it can be done by RSS?
If so, How?
PLEASE HELP ME.
