XQUERY-
- XQuery uses functions to extract data from xml documents.
- Uses path expressions to navigate through elements in an xml document.
- Can also transform the xml document into other format.
- XQuery is case sensitive.
- An XQuery variable is defined with a $ followed by a name.
- XQuery has the potential to become the most applicable language for extracting and transforming data from any source that can be represented as a real or virtual XML document.
