Needed help. urgent.

I want to generate an nine digit unique random number and store it in an xml file.

I should be able to append the xml file each time when I generate a new random number.

And also when it generates a new rondom number it should make sure that number dosen't

already exist in the xml file. Any help would be appreciated.
