js操作xpath

function xpath(source, urlXpath) {
    const parse = new DOMParser();
    const doc = parse.parseFromString(source, 'text/html');
    const resultIterator = doc.evaluate(urlXpath, doc, null, XPathResult.ANY_TYPE, null);
    let resultNode = resultIterator.iterateNext();
    while (resultNode) {
        var value = resultNode.textContent
        console.log(value)
        resultNode = resultIterator.iterateNext();
    }
}

var xpathHelper = () => {
    var source = document.documentElement.innerHTML
    var current_xpath = "//div[@class='wrapper clearfix'][3]/div[@class='content'][1]/div[@class='content-mod'][1]/ul[@class='content-list imglazyload'][1]/li/div[@class='info-mod clearfix'][1]/div[@class='info-head'][1]/a[1]"
