问题描述

您好，我想在导航后提取的innertext标签&NBSP;但它很难，因为它来了一个完整的列表，但我想逐一提取它然后把它放在列表视图中...

文档：

 看来我做错了。我希望它能够提取每个跨度的innertext，这样我就可以将它放在listview单元格中。
 请注意，这是我正在研究的一个项目非常重要。

</li><li class="video-list-item related-list-item ">    <div class="content-wrapper">
    <a href="https://www.youtube.com/watch?v=94Rq2TX0wj4" class="content-link spf-link  yt-uix-sessionlink" rel="spf-prefetch" title="Martin Solveig &amp; GTA - Intoxicated (Official Music Video)" data-sessionlink="ei=VDvNVJ-XI6a3-APo7YDYBw&amp;feature=relmfu&amp;ved=CAYQzRooAw">  <span dir="ltr" class="title" aria-describedby="description-id-785839">

MY CODE:
 Dim dc As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("li")
        For Each jg As HtmlElement In dc
            Dim kl As String = jg.OuterHtml
            If kl.Contains("yt-uix-scroller-scroll-unit") Then

                Dim kd As HtmlElementCollection = jg.GetElementsByTagName("a")
                For Each kw As HtmlElement In kd
                    Dim kkCOLLECTION As HtmlElementCollection = kw.GetElementsByTagName("span")
                  
                        Dim dd As String = jg.GetAttribute("data-video-title")

                        For Each nn As String In pl
                            For Each nnn As String In pll
                                For Each nnnn As String In plll

                                    ListView1.Items.Add(lvi)
                                 
                                Next
                            Next
                        Next
