public abstract class XmlRef
Base class for E4X XML attribute-access or property-get expressions. Such expressions can take a variety of forms. The general syntax has three parts:
@
Name
) and double-colonName
or a bracketed [expression]ns::name
, @name
)
are represented as XmlPropRef
nodes. The bracketed-expression
versions (examples: ns::[name]
, @[name]
) become
XmlElemRef
nodes.
This node type (or more specifically, its subclasses) will
sometimes be the right-hand child of a PropertyGet
node or
an XmlMemberGet
node. The XmlRef
node may also
be a standalone primary expression with no explicit target, which
is valid in certain expression contexts such as
company..employee.(@id < 100)
- in this case, the @id
is an XmlRef
that is part of an infix '<' expression
whose parent is an XmlDotQuery
node.
