问题描述

I am stuck in a problem i just want to extract data from x-path attribute selector this is the div and span who's inner text want to show please help me out.
I am also performing this option in 16 times in a for each loop.

    <div class="l">
   <span id="ls_title_7596012" class="ls_h_desc" title="Required 10 marla old house in any block of bahria town">Required 10 marla old house in any block of bahria town</span>
   </div>
I am also trying this but not succeed.

What I have tried:

var name = htmlDocument?.DocumentNode?.SelectNodes("//div[@class=\"1\"]//span[@class=\"ls_h_desc\"]//title")[0].InnerText;

推荐答案

显而易见的问题是，您显示的< div> 的类别为 l - 小写 L - 而您正在搜索 1 的类。



你还试图选择一个名为 title 的元素，它不存在;显示的标题是属性。

The obvious problem is that the <div> you've shown has a class of l - a lower-case L - whereas you're searching for a class of 1.

You're also trying to select an element called title, which doesn't exist; the title shown is an attribute.

var name = htmlDocument?.DocumentNode?.SelectNodes("//div[@class=\"l\"]//span[@class=\"ls_h_desc\"]")[0].InnerText;

你试过jQuery吗？选择器？



i没有测试，但这样的事情应该有效

did you try jQuery selector?

i didn't test but something like this should work

（div.l> span.ls_h_desc）。val（）

("div.l > span.ls_h_desc").val()
