You have two options:
<1> 2 x XLR-f > stereo mini male
<2> stereo mini male > stereo mini male
Option <2>'s signal will be 6 dB lower than <1>. FWIW, I used to run <2>. Depending on how you run your gear physically (in bag, pockets, etc.), you may or may not want to consider right-angle cables. These cables are available via Kind Kables, probably your local musicians gear store, and possibly Radio Shack.
