XPathResult
The XPathResult interface represents the results generated by evaluating an XPath 1.0 expression within the context of a given node. Since XPath expressions can result in a variety of result types, this interface makes it possible to determine and handle the type and value of the result.

Constants
ANY_TYPE | 0 | A result set containing whatever type naturally results from evaluation of the expression. Note that if the result is a node-set then UNORDERED_NODE_ITERATOR_TYPE is always the resulting type. |
NUMBER_TYPE | 1 | A result containing a single number. This is useful for example, in an XPath expression using the count() function. |
STRING_TYPE | 2 | A result containing a single string. |
BOOLEAN_TYPE | 3 | A result containing a single boolean value. This is useful for example, in an XPath expression using the not() function. |
UNORDERED_NODE_ITERATOR_TYPE | 4 | A result node-set containing all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document. |
ORDERED_NODE_ITERATOR_TYPE | 5 | A result node-set containing all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document. |
UNORDERED_NODE_SNAPSHOT_TYPE | 6 | A result node-set containing snapshots of all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document. |
ORDERED_NODE_SNAPSHOT_TYPE | 7 | A result node-set containing snapshots of all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document. |
ANY_UNORDERED_NODE_TYPE | 8 | A result node-set containing any single node that matches the expression. The node is not necessarily the first node in the document that matches the expression. |
FIRST_ORDERED_NODE_TYPE | 9 | A result node-set containing the first node in the document that matches the expression. |
