Question

One of the components that I use needs to feed an XML into it. The component provider has not provided any documentation or the specs of the XML. I am trying to generate the XMLs by trial and error using the sample XMLs from the component.

This was the story. Here is my problem.
In the XML, they have used some f_key = "b3f39bb9-3f8c-453a-bdb4-2486a887e39f-0000a008:000001e8"

Java gives me this : UUID.randomUUID().toString()
which generates random strings in this format : "22572e59-f7dc-404a-9c0c-78161e3a4df7"

Any clue, what does “0000a008:000001e8” in the f_key provided by the component mean [The random string up to 5 pieces matches in both. The 6th and 7th piece are extra in the random string provided by the component]? What sort of UUID generator would be generating that? Does it look familiar?

According to this code

Regex guidRegEx = new Regex(@"^(\{{0,1}([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}\}{0,1})$");
guidRegEx.IsMatch("b3f39bb9-3f8c-453a-bdb4-2486a887e39f-0000a008:000001e8");

that isn’t a valid guid, its a valid guid with something on the end. I am guessing they’ve tacked a timestamp on the end. I’ve seen stuff come out of timestamp appliances in the past.

But that is a best guess.
