XPathExpression
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.
This interface is a compiled XPath expression that can be evaluated on a document or specific node to return information from its DOM tree.
This is useful when an expression will be reused in an application, because it is just compiled once and all namespace prefixes which occur within the expression are preresolved.
Objects of this type are created by calling XPathEvaluator.createExpression().
Instance methods
XPathExpression.evaluate()-
Evaluates the XPath expression on the given node or document.
Example
The following example shows the use of the XPathExpression interface.
HTML
html
<div>XPath example</div>
<div>Number of <div>s: <output></output></div>
JavaScript
js
const xpath = "//div";
const evaluator = new XPathEvaluator();
const expression = evaluator.createExpression(xpath);
const result = expression.evaluate(
document,
XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
);
document.querySelector("output").textContent = result.snapshotLength;
