XPointer extensions to XPath
- XPath
Node concept is extended to nodes, points and ranges
and associated cast functions
- A
string-range() function to address within (nodes) content
- The functions
here() and origin() to refer to
the XPointer expression location and hypertext traversal
- The functions
start-point() and end-point() to
address beginning and ending of locations.
- The
unique() function to detect absence or multiple return
values.
- Initialization of the XPath context
