java.lang.Objectorg.mozilla.javascript.Node
org.mozilla.javascript.ast.AstNode
org.mozilla.javascript.ast.XmlRef
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.
