There exists a peculiar amnesia in software engineering regarding XML. Mention it in most circles and you will receive knowing smiles, dismissive waves, the sort of patronizing acknowledgment reserved for technologies deemed passé. “Oh, XML,” they say, as if the very syllables carry the weight of obsolescence. “We use JSON now. Much cleaner.”
Biggest problem is, CSV is not a standardized format like JSON. For very simple cases it could be used as a database like format. But it depends on the parser and that’s not ideal.
