I use wolf ammo in my .223 AK, and it eats it just fine. But, as previously stated, these guns are designed to shoot just about anyting that will fit in the chamber. However, I have shot Wolf 9mm and a few other calibers, with no problems in any of my firearms. The trick seems to be not to buy the lacquer coated case stuff. that's when you start getting the PITA to clean situation. And as far as being able to shoot it through your XD? I'd say why not? Any quality firearm (IMHO) should be able to handle what ever you throw at it(with proper care and cleaning). I would definately say that your XD is a quality firearm, so I wouldn't worry about it. It does tend to wear extractors out a little faster though(steel being a lot harder than brass) and you can not reload it either(which sucks for us who like to reload). The question you should ask yourself is, Is all this worth the few dollars you'll save per box?
Shoot it, see if it performs well for you. Clean the gun, see if it is too much of a PITA. Then decide for yourself. You also might want to do a google on the Ballistics for the specific caliber of wolf you'd like to shoot, and compare that to other brands. Just my two cents.
