Hello @espressodaily, do I understand correctly, that this is related to the "Web Scraper" Actor? If so, you can use the document.evaluate method. For example:

async function pageFunction() {
    const headerText = document.evaluate('//h3', document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null).snapshotItem(0).textContent;
    console.log(`header: ${headerText}`);
    return { headerText };
}

async function pageFunction() {
    const headerText = document.evaluate('//h3', document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null).snapshotItem(0).textContent;
    console.log(`header: ${headerText}`);
    return { headerText };
}

sorry, yes! thanks for the response. is it possible to pass variables, e.g. item to extract and xpath from api so that it is not hard coded in pageFunction?
