While this might be true for your sample, in general, a statement like 
this always concerns me.

 From XRD, you can say is that there is no /crystalline/ side phase 
formation and that there is no contamination in the /diffracting/ 
/portion/ of the sample.

It is very common when preparing nanoparticulate matter for there to be 
non- or poorly-diffracting content in the sample.  If that content 
contains the absorbing element, then it will have an impact on the XAS data.
