org.mozilla.javascript.ast.XmlRef
org.mozilla.javascript.ast.XmlElemRef
public class XmlElemRef
AST node for an E4X XML [expr] member-ref expression.
The node type is Token.REF_MEMBER.
Syntax:
@opt ns:: opt [ expr ]Examples include
ns::[expr], @ns::[expr], @[expr],
*::[expr] and @*::[expr].
Note that the form [expr] (i.e. no namespace or
attribute-qualifier) is not a legal XmlElemRef expression,
since it's already used for standard JavaScript ElementGet
array-indexing. Hence, an XmlElemRef node always has
either the attribute-qualifier, a non-null namespace node,
or both.
The node starts at the @ token, if present. Otherwise it starts
at the namespace name. The node bounds extend through the closing
right-bracket, or if it is missing due to a syntax error, through the
end of the index expression.

AstNode
Note: if the parser was in error-recovery mode, some AST nodes may have
null children that are expected to be non-null
when no errors are present. In this situation, the behavior of the
toSource method is undefined: toSource
implementations may assume that the AST node is error-free, since it is
intended to be invoked only at runtime after a successful parse.
toSource in class AstNodedepth - the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit in class AstNodev - the object to call with this node and its children
