Can we make this XPath a little easier to read perhaps? I still need to test it, but seems like something as follows should do the same without requiring arithmetic:
./*[not(contains(concat(" ", @class), " h-")) and count(../*) = 1 and count(img) = 1]/img
count(../*)counts the number of child elements of the parent. In other words our*is only matched if it is the only child (= 1).count(img)counts the number of childimgelements within. So*is only matched if it contains only a singleimg(= 1).
This gets rid of all the sibling counting, summations, etc. Could also be adapted for object elements.
Simplified xpath count() using traversal. Added selectors from spec as comments. Moved child h-* check into xpaths. Added check for xpath query() returning false.

Without resolving here, the implied values from img.h-x[src] and object.h-x[data] will never get resolved. Why not keep resolveUrl() here?

I can add resolveUrl to those two. My thinking is parseImpliedPhoto() should return an absolute URL or false.
