Xpath 和通配符
我尝试了几种组合但没有成功。该数据的完整 xpath 为 .//*[@id='detail_row_seek_37878']/td 问题是每个节点的数字部分“37878”发生变化，因此我无法使用 foreach循环遍历节点。有没有办法使用通配符并将 xpath 减少为 .//*[@id='detail wildcard，以绕过绝对值部分？我在此使用 html 敏捷包。
HtmlNode ddate = node.SelectSingleNode(".//*[@id='detail_row_seek_37878']/td");
I have tried several combinations without success. The full xpath to that data is .//*[@id='detail_row_seek_37878']/td The problem is the number portion '37878' changes for each node and thus I can't use a foreach to loop through the nodes. Is there some way to use a wildcard and reduce the xpath to .//*[@id='detail wildcard, in an effort to bypass the absolute value portion? I am using html agility pack on this.
HtmlNode ddate = node.SelectSingleNode(".//*[@id='detail_row_seek_37878']/td");
