Method toMap

src/main/java/groovy/util/Node.java:908–956

Converts this Node tree into a nested Map . Attributes and child elements are merged into a single map keyed by name. If a child element name collides with an attribute name, the child element wins. Leaf child elements (text only, no attributes) become String values. Non-l
