Chrome/Edge XPath 提取 HTML 上下文节点

在控制台 console 输入下述函数，即可通过 xpath 提取 $x(...) 的上下文

const xpath = function (xpath, context=document) {
  var nodes = [];
  try {
    var doc = (context && context.ownerDocument) || window.document;
    var results = doc.evaluate(xpath, context || doc, null, XPathResult.ANY_TYPE, null);
    var node;

    while (node = results.iterateNext()) {
      nodes.push(node);
    }
  } catch (e) {
    throw e;
  }
  return nodes;
}

示例

$x('//a[contains(@class,"meeting-list-item")]').map(
	x => console.log(
		xpath('.//div[contains(@class, "content")]/text()', x)[0].nodeValue
		,xpath('./@href', x)[0].nodeValue)
)
