Distinguish, differentiate, compare and explain what is the difference between XML and JSON. Comparison and Differences.
What is XML?
XML is a language that captures information in a machine-readable way. The elements are structured in a hierarchy and all information is included between tags. All tags have to be kept opened and closed in the level they belong to. Therefore, every piece of information is logically categorized and named. The rules defining how the information is captured is documented in a schema and the schema is the blueprint for every document and allows validation of the content.
What is JSON?
Difference between XML and JSON
|1||Uses XSD Validation||Has no Validation|
|2||Includes namespaces||No requirement of namespaces|
|3||Requires parsing and XML doc is parsed through parameters like xpath etc.||In JSON, parsing is just an eval. Therefore it is fast.|
|6||It is heavy||It is light weight|
JSON was originally meant to replace XML, however it did not replace it in every case. The need of an implicit validation of a document still makes XML an option to consider. XML is a format that is designed to store and archive documents because of its ability to contain validated transparent data. XML is NOT a thin format to be used to transport data. Its larger and more data-heavy structure decreases the performance of a transmission between applications.
The disadvantages of XML are the main advantages of JSON. The JSON structure concentrates on the data, lowering the overhead. The way JSON self-describes, makes it the best performing data format to transport heterogenic data. Lastly, and perhaps its best argument in favor of it, JSON is much cheaper to integrate.
