Because array must be iterated through, while a DOM document can be searched
via XPath by a simple /*/classname (or something; I must refresh my Xpath
skills). Of course that XML needs more memory, but I'd like to know
generally which is faster, iterating arrays or DOM document creation + Xpath
search. Intuitively I'd also go for the first, but I'm asking if someone has
any first-hand experience.
