XML conflates a bunch of stuff (XSLT, XPath, Schemas, namespaces, etc....) making it overly complicated
Then it has 3 different sets of data, elements, attributes, content. In other words <a c="foo">bla<b/>bla</a> is mess to deal with. Now replace the "bla" with spaces and assume <a> is supposedly only supposed to have <b> as a child except really it will have 3 children, the one before the <b> and the one after.
I think this is why JSON won over XML. It seems like all those extra features on XML would be a benefit but in reality they just give you more places to hang yourself.
