XML and JSON are not immune to similar problems, but in my experience you run into it head first with YAML more because when copy/pasting YAML stanzas from one document to another, the indentation can (and often does) get mangled. Since whitespace isn't meaningful you can paste a JSON or XML object as without the whitespace, parse the document and then reformat it to display it nicely. With YAML if the whitespace gets mangled on paste then the document can't be parsed to begin with so the tools you generally use to debug such issues are largely useless. You are effectively back to raw text.
