The read-only snapshotLength property of the XPathResult interface represents the number of nodes in the result snapshot.

var snapshotLength = result.snapshotLength;

An integer value representing the number of nodes in the result snapshot.

In case XPathResult.resultType is not UNORDERED_NODE_SNAPSHOT_TYPE or ORDERED_NODE_SNAPSHOT_TYPE, an XPathException of type TYPE_ERR is thrown.

The following example shows the use of the snapshotLength property.

<div>XPath example</div>
<div>Number of matched nodes: <output></output></div>

var xpath = "//div";
var result = document.evaluate(xpath, document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);
document.querySelector("output").textContent = result.snapshotLength;
