Functions: EndPoint, Here, Origin, Range, RangeInside, RangeTo, StartPoint, StringRange, Unique |  |  |  | Fields: CoreFunctions, EMPTY_NAMESPACE

## Functions

EndPoint(context, point)
<point> end-point(<point>)
For each location x in the argument location-set, end-point adds a location
of type point to the result location-set.
Here(context)
<location-set> here()
The here function returns a location-set with a single member. That
location locates the node that directly contains the XPointer being
evaluated.
Origin(context)
<location-set> origin()
The origin functions enables addressing relative to out-of-line links
such as defined in XLink. This allows XPointers to be used in applications
to express relative locations when links do not reside directly at one of
their endpoints. The function returns a location-set with a single member,
which locates the element from which a user or program initiated traversal
of the link.
Range(context, locationSet)
<location-set> range(<location-set>)
The range function returns ranges covering the locations in the argument
location-set. For each location x in the argument location-set, a range
location representing the covering range of x is added to the result
location-set.
RangeInside(context, locationSet)
<location-set> range-inside(<location-set>)
The range-inside function returns ranges covering the content of the
locations in the argument location-set. For each location x in the
argument location-set, a range location is added to the result location-set.
RangeTo(context, expr)
<location-set> range-to(<expr>)
For each location in the context, range-to returns a range.
StartPoint(context, point)
<point> start-point(<point>)
For each location x in the argument location-set, start-point adds a
location of type point to the result location-set.
StringRange(context, string, startPos=1, length=None)
<location-set> string-range(<location-set>, <string>, <number>?, <number>?)
For each location in the location-set argument, string-range returns a set
of string ranges, a set of substrings in a string.
Unique(context)
<boolean> unique()
The predicate function unique returns true if and only if context size is
equal to 1.
