Linq to Xml sorting

Hey,

I am attempting to sort an xml file by 2 variables the Signal name and the Size, here is what I have tried so far


Which gives me the data sorted like so


and I tried this


and I gets this


In theory the 2nd try should work, I want it so that the signals are the primary and then the size is arranged in order within the signal... so

instead of

Code:

---

Signal : 1221 Size : AWG 18
Signal : 1221 Size : AWG 18
Signal : 1221 Size : AWG 16
Signal : 1221 Size : AWG 18
Signal : 1221 Size : AWG 16
Signal : 1221 Size : AWG 18
Signal : 1221 Size : AWG 18
Signal : 1221 Size : AWG 18

---

The Size AWG 16 should either be first or last and not in between, I do not know why it does not catch that ? :S
