HTML敏捷包，无法选择节点

我有以下HTML代码

<a href="http://www.google.de/products/catalog?hl=de&amp;newwindow=1&amp;q=6411920054105&amp;um=1&amp;ie=UTF-8&amp;cid=12216375657503902223&amp;sa=X&amp;ei=8nWWUOvADonntQbP3IHgDw&amp;ved=0CEgQ8gIwAA" class="psliimg" target="_blank">
<img src="https://lh5.googleusercontent.com/public/OCXiCAAYqFb859nA0DsbPbBSBR2EYU8IFnl_xtJxG2t1_z_xlLiRjxt5HPa0XFZBT1nch4a1j8PAAr4SVs974R_KnJI83sDB303YlcZQD9L5kmKUdTKXfLfJM_lovWyQcf4UlZkXb8sMarIamxSytCjB-aM=s90-c" alt="iittala Aalto Vase apfelgrün 16cm">
</a>

但是我可以通过选择它的子对象来获得它，但是当我尝试访问除href以外的任何其他属性时，它都无法工作！如果我尝试获得属性的计数，它会给我一个，即使有3个

这是原件，您可以测试一下，是什么原因造成的？

您希望从发布的htlm代码中得到什么

我运行了它，并试图测试自己，得到了同样的错误。因此，我在下面运行了这段代码，写入控制台的文本甚至不包含class=psliimg属性，因此我不确定从页面读取原始html代码和HAP如何处理这段代码之间会发生什么

Sub Main()
    Dim web As HtmlWeb = New HtmlWeb
    Dim doc As HtmlDocument = web.Load("https://www.google.de/search?hl=de&tbm=shop&q=6411920054105&oq=6411920054105&gs_l=products-cc.12...3450.3450.0.4463.1.1.0.0.0.0.334.334.3-1.1.0...0.0...1ac.1.fBfILtFfII0")

    Dim str = doc.DocumentNode.SelectSingleNode("//a[contains(@href,'12216375657503902223')]").ParentNode.InnerHtml
    'The long munber is contained in the html line and is just used to identify the node I want to select.
    Console.WriteLine(Str)
    Console.ReadKey()
End Sub

以下是输出：

抱歉，这不是一个真正的答案，但不知道发布代码片段的最佳方式

    For Each link As HtmlNode In doc.DocumentNode.SelectNodes("//a[@href]")
        'Console.WriteLine(link.ParentNode.InnerHtml)
