第一你应该为你的项目添加refernece - Microsoft.mshtml，

然后按名称空间mshtml你将有权访问HTMLDocumentClass


MS

Hi,

First you should add refernece to your project - Microsoft.mshtml,
then by namespace "mshtml" you will have access HTMLDocumentClass

M.S

我做了你告诉我的方式。让我清楚一下这个问题。

我有一个HTML文本存储在一个字符串中说strResponseHTML"变量。

我尝试使用的代码如下：


private void button1_Click（object sender，System.EventArgs e）

{

HTMLDocument htmlDoc = new HTMLDocumentClass（）;

IHTMLDocument2 doc =（IHTMLDocument2）new HTMLDocumentClass（）;

try

{

string strResponse = getHtml（）;

htmlDoc.write（strResponse）;

if（null！ = htmlDoc）

{

MessageBox.Show（htmlDoc.all.length.ToString（））;

}

richTextBox1.Text = htmlDoc.toString（）;

}

catch（例外情况）

{

MessageBox.Show（ex.Message +" \ n" + ex.StackTrace）;

}

}


现在看到代码后，实际上我想要做的是我想要
解析响应HTML以查找带有值的一些对象。我想要比较的那些

值。

我们使用MSXML2.dll使用XMLDOM解析XML文档，类似我们可以

使用MSHTML.dll使用htmlDocument对象解析HTML文档。但是如何将strResponseHTML加载到HTMLDocument对象中，我想知道。

如果有任何机构可以帮助我，那么高度相关。

谢谢

Hi,
I did the way you just told. Let me clear about the problem.
I am having one HTML text stored in a string say "strResponseHTML" variable.
The code which I am trying to use is as follows:

private void button1_Click(object sender, System.EventArgs e)
{
HTMLDocument htmlDoc = new HTMLDocumentClass();
IHTMLDocument2 doc = (IHTMLDocument2)new HTMLDocumentClass();
try
{
string strResponse = getHtml();
htmlDoc.write(strResponse);
if (null != htmlDoc)
{
MessageBox.Show(htmlDoc.all.length.ToString());
}
richTextBox1.Text= htmlDoc.toString();
}
catch(Exception ex)
{
MessageBox.Show(ex.Message + "\n"+ex.StackTrace);
}
}

Now upon seeing the code, what actually I am trying to do is that I want to
parse the response HTML to look for some objects with the values. Those
values I would like to compare.
We use MSXML2.dll to parse the XML document using XMLDOM, similary we "can"
use MSHTML.dll to parse the HTML document using htmlDocument object. But how
to load the strResponseHTML into HTMLDocument object, that I want to know.
If any body could help me out, highly appreaciated.
Thanks
Atul

您好，

首先，您应该为您的项目添加参考 - Microsoft.mshtml，
然后是名称空间mshtml你将有权访问HTMLDocumentClass

MS

Hi,

First you should add refernece to your project - Microsoft.mshtml,
then by namespace "mshtml" you will have access HTMLDocumentClass

M.S

Atul，


为了这样做，你将不得不使用HTMLDocument实现的IPersist接口之一

。您可以使用IPersistFile界面，

将字符串保存到文件然后以这种方式加载，或者您可以使用IPersistMemory接口使用

，将字符串放入非托管内存并且

然后将指针传递给内存中的该字符串。


但是，如果您在本文档中有相对URL，则需要

已经正确解决，那么这将无效。原因是

类不知道文件的来源，也无法解决这些问题。在这种情况下，您将不得不创建一个实现

的IMoniker（在System.Runtime.InteropServices

命名空间中表示，名称为UCOMIMoniker）。 />

当你创建这个实现时，你必须实现

BindToStorage方法，以便它返回一个IStream实现（

COM最终要求的界面）。这个IStream会将您返回到MSHTML的

字符串流式传输。


此外，您还需要实现
$的GetDisplayName方法b $ b UCOMIMoniker接口，以便它返回此字符串从下载的
的URL。


希望这会有所帮助。

Atul,

In order to do this, you will have to use one of the IPersist interfaces
that HTMLDocument implements. You can use the IPersistFile interface,
saving your string to a file and then loading it that way, or you could use
the IPersistMemory interface, placing your string into unmanaged memory and
then passing the pointer to that string in memory.

However, if you have relative URLs in this document which you need to
have resolved correctly, then this will not work. The reason is that the
class doesn''t know about where the document came from, and can not resolve
these accordingly. In this case, you will have to create an implementation
of IMoniker (which is represented in the System.Runtime.InteropServices
namespace with a name of UCOMIMoniker).

When you create this implementation, you have to implement the
BindToStorage method so that it will return an IStream implementation (the
COM interface) which is asked for eventually. This IStream will stream the
string that you had back to MSHTML.

Also, you will want to implement the GetDisplayName method of the
UCOMIMoniker interface so that it returns the url that this string was
downloaded from.

Hope this helps.
