      • toMap

        java.util.Map<java.lang.String,​java.lang.Object> toMap​(org.w3c.dom.Node node)
        Returns a Map object based on the given node.

        The conversion rules are as follows:

        Elements
        A XML element node will behave depending on its nature.
        If the element node is a simple element node, then its value will become available under the node name.
        For example, the given XML node:
        <myNode>Some text<![CDATA[other text]]>another text</myNode> If the node is referenced like var myValue = myMap.myNode;, the variable myValue will have the value Some textother textanother text.
        It is important to notice that no white space will be automatically included between text and CDATA nodes.

        If the element node is a simple element node with attributes, then its value will become available under the $ object, inside the node object.
        For example, the given XML node:

        <myNode myAttribute="1">Some text<![CDATA[other text]]>another text</myNode> If the node is referenced like var myValue = myMap.myNode.$;, the variable myValue will have the value Some textother textanother text.
        It is important to notice that no white space will be automatically included between text and CDATA nodes.

        If the node is a complex node then its text (inner CDATA sections and text nodes) will not be accessible. This kind of node is simply a container for inner nodes.
        For example, the given XML node:

        <myNode>Some text<![CDATA[other text]]>another text<myOtherNode>Other node text</myOtherNode></myNode> The text of node myNode will not be accessible at all and the text of node myOtherNode will be accessible using myMap.myNode.myOtherNode.

        Another aspect of element nodes is when they are automatically wrapped in arrays. It happens in the following situations:

        • If some element node has at least one sibling node with the very same name.
        • If an element node has the attribute lumIsArray with the value true.
        • If the parent node of some element node has a name that is the concatenation of the child node with the "s" suffix and the child element node either doesn't have the lumIsArray attribute or the value of lumIsArray attribute is not false.
        • If the element node has the name row and its parent node name is data and the child element node either doesn't have the lumIsArray attribute or the value of lumIsArray attribute is not false.
        Attributes
        A XML element node attribute named myAttribute becomes available using the name $myAttribute. For example, the given XML node:
        <myNode myAttribute="someValue"/> Makes the attribute myAttribute available using myNode.$myAttribute.

        Simple element node
        Simple element node is a node that has the following aspects:
        • Has no attributes.
        • All of inner nodes are either CDATA sections or text nodes (comments are ignored).
        Simple element node with attributes
        Simple element node with attributes is a node that has the following aspects:
        • Has at least one attribute.
        • All of inner nodes are either CDATA sections or text nodes (comments are ignored).
        Simple element node value
        The value of a simple element node is the concatenation of all inner CDATA sections and text nodes.
        Complex node
        A complex node is a node that has at least one inner node that is neither a CDATA section nor a text node.
        Parameters:
        node - the node to be transformed in Map.
        Returns:
        a object based on the given node.
