The read-only resultType property of the XPathResult interface represents the type of the result, as defined by the type constants.
An integer value representing the type of the result, as defined by the type constants.
| Result Type Defined Constant | Value | Description |
|---|---|---|
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. |
The following example shows the use of the resultType property.
<div>XPath example</div>
<div>Is XPath result a node set: <output></output></div>const xpath = "//div";
const result = document.evaluate(
xpath,
document,
null,
XPathResult.ANY_TYPE,
null,
);
document.querySelector("output").textContent =
result.resultType >= XPathResult.UNORDERED_NODE_ITERATOR_TYPE &&
result.resultType <= XPathResult.FIRST_ORDERED_NODE_TYPE;
