Select nodes along a relative or absolute path.
A LocationPath selects a set of nodes either relative to
the context node if it is a RelativeLocationPath or relative to
the root node if it is an AbsoluteLocationPath. The result of
evaluating a location path expression is the node set containing the nodes
selected by the location path. Location paths can recursively contain
expressions that are used to filter sets of nodes.
It corresponds to the expression LocationPath defined in
XPath, Section 2,
Rule 1.
Select all patients (using a relative location path select all
patient nodes starting from the context node which is the same as
the collection's doctype element):
patient
Select all male patients sorted by their first names (using an
absolute location path select all patient nodes that have a child
element node sex whose value matches the pattern
"male"; sort this node-set by the element
/patient/name/firstname which must have been defined with
Search-Type set to "Standard" in the schema
definition):
/patient[sex ~= 'male'] sortby (./name/firstname)
