The read-only singleNodeValue property of the XPathResult interface returns a Node value or null in case no node was matched of a result with XPathResult.resultType being ANY_UNORDERED_NODE_TYPE or FIRST_ORDERED_NODE_TYPE.
The read-only singleNodeValue property of the XPathResult interface returns a Node value or null in case no node was matched of a result with XPathResult.resultType being ANY_UNORDERED_NODE_TYPE or FIRST_ORDERED_NODE_TYPE.
The return value is the Node value of the XPathResult returned by Document.evaluate().
In case XPathResult.resultType is not ANY_UNORDERED_NODE_TYPE or FIRST_ORDERED_NODE_TYPE, an XPathException of type TYPE_ERR is thrown.
The following example shows the use of the singleNodeValue property.
html
<div>XPath example</div> <div> Tag name of the element having the text content 'XPath example': <output></output> </div>
js
const xpath = "//*[text()='XPath example']"; const result = document.evaluate( xpath, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null, ); document.querySelector("output").textContent = result.singleNodeValue.localName;
