It does not use regular expressions, which are inappropriate for this task.

SAX (Simple API for XML) is an event-driven online algorithm for parsing XML documents, with an API developed by the XML-DEV mailing list. SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM).

Jsoup provides methods that operate on the Document, on a set of Elements, or on a specific Element, allowing you to navigate to a node’s parents, siblings, or children.
