XML, JSON & Data Interchange
XML, JSON & Data Interchange is a beginner course on the two standard formats used to exchange structured data between systems. Over 3 weeks, learners read JSON and XML values and validate data before exchange, then progress to schema validation, JSONPath/XPath/XSLT, streaming parsers, and security concerns like XXE attacks — suited to anyone new to data interchange.
Read JSON values. Read well-formed XML. Check data before exchanging it.
