XPath performs the addressing of knots in an XML instance. The following concepts are relevant for this addressing:

• The XML instance
• The JAXFront-type-tree (JAXFront DOM).

It is important to know what is addressed with an XPath statement:

• A list of elements 
• All elements
• A single element

JAXFront uses its own XPath extension, because the "normal" XPath syntax does not distinguish between list types (container) and the contents of their element.

• /../NodeA[list]
• /../NodeB[text]
• /../NodeA[3]
