My reasons to hate XML:
- element vs attribute ambiguity
- model of the document does not fit nicely to programming model of structs, dicts and arrays
- too many complexities (entities, cdata, parser directives)
- cardinality unknown without schema (is that a single value, or an array that just happens to have one element)
- order of elements may or may not be significant depending on schema
- not really extensible if the original schema does not explicitly allow for extensibility
- some types of valid XML documents are not representable by a schema (e.g. any number of different elements in any order)
- verbosity
- namespace identifiers being URIs that may or may not be resolvable
What I want for general data exchange is JSON with comments and sane namespaces.
Edit: line wraps
