XPathResult: singleNodeValue property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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.
Value
The return value is the Node value of the XPathResult
returned by Document.evaluate().
Exceptions
TYPE_ERR
In case XPathResult.resultType is not
ANY_UNORDERED_NODE_TYPE or FIRST_ORDERED_NODE_TYPE, a
DOMException of type TYPE_ERR is thrown.
Examples
The following example shows the use of the singleNodeValue property.
HTML
html
<div>XPath example</div>
<div>
Tag name of the element having the text content 'XPath example':
<output></output>
</div>
JavaScript
