Summary

XML can express, or model, many types of data structures, including structures that are similar to relational data, hierarchical data, and loosely structured data.

Data models provide the way for programming languages to efficiently and conveniently create, modify, or manipulate XML data. Three data models were introduced in this chapter—the Document Object Model, the XML Path Language, and the XML Information Set.
