C#通过HtmlElement访问标签属性(C# Access tags properties by HtmlElement)

有一个像:

<div id="instance" style="color:red;display:block;  .... bila bila">
   <h2>some text</h2>
</div>

我想通过这个代码访问div的样式;

foreach (HtmlElement link in webBrowser1.Document.GetElementsByTagName("div"))
{
   if (link.GetAttribute("id").ToString() == "instance")
   {
      MessageBox.Show(link.innerhtml);
   }
}

但是link.innerhtml给了我div标签的内部,而不是div自己的。 Messag.Box的输出文本是:

<h2>some text</h2>

我也试过这个:

MessageBox.Show(link.GetAttribute("style"));

但它没有用。

如何通过相同div的id访问div属性?


There is an html like:

<div id="instance" style="color:red;display:block;  .... bila bila">
   <h2>some text</h2>
</div>

I wanna access style of div via this code;

foreach (HtmlElement link in webBrowser1.Document.GetElementsByTagName("div"))
{
   if (link.GetAttribute("id").ToString() == "instance")
   {
      MessageBox.Show(link.innerhtml);
   }
}

But link.innerhtml gives me the inside of div tag, not div's own. Output text of Messag.Box is:

<h2>some text</h2>

I also tried this too:

MessageBox.Show(link.GetAttribute("style"));

but it didnt work.

How to access div properties via same div's id?

你可能会碰到Python自己的commands模块(它没有类似你的子模块)的冲突 - 以隐藏标准库中的模块和包的方式命名你自己的模块和包(就像命名变量的方式一样意在隐藏内建名称,如listfile )始终是一项危险的工作,尽管它“应该”起作用,但始终存在混淆的可能性。

你能否尝试将commands包及其用途重命名为明确且没有危险的内容,例如mycommands ,并查看是否会使问题消失? 如果是这种情况,你可以在GAE的跟踪器上打开一张票(因为它会在GAE的运行时显示一个小的但不可否认的错误),但同时你的问题已经解决了! - )如果问题依然存在,那么至少我们已经消除一个可能的原因,并可以继续挖掘...


You could be running into a clash with Python's own commands module (which doesn't have submodules like yours) -- naming your own modules and packages in ways that are meant to hide ones in the standard library (just like naming your variables in ways that are meant to hide builtin names, like list or file) is always a perilous undertaking, even though it "should" work there's always potential for confusion.

Could you try renaming that commands package and its uses to something unambiguous and free from danger, such as mycommands, and see if that just makes the problem disappear? If that's the case you can then open a ticket on GAE's tracker (because it would show a minor but undeniable bug in GAE's runtime) but meanwhile your problem is solved!-) If the problem stays, ah well, at least we've eliminated one likely cause and can keep digging...
