XML vs YAML: What are the differences?

Developers describe XML as "A simple, very flexible text format". A markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. On the other hand, YAML is detailed as "A straightforward machine parsable data serialization format designed for human readability and interaction". A human-readable data-serialization language. It is commonly used for configuration files, but could be used in many applications where data is being stored or transmitted.

XML and YAML can be primarily classified as "Languages" tools.
