The read-only stringValue property of the XPathResult interface returns the string value of a result with XPathResult.resultType being STRING_TYPE.
The return value is the string value of the XPathResult returned by Document.evaluate().
In case XPathResult.resultType is not STRING_TYPE, a DOMException of type TYPE_ERR is thrown.
The following example shows the use of the stringValue property.
<div>XPath example</div>
<div>Text content of the &lt;div&gt; above: <output></output></div>const xpath = "//div/text()";
const result = document.evaluate(
xpath,
document,
null,
XPathResult.STRING_TYPE,
null,
);
document.querySelector("output").textContent = result.stringValue;
