求助，存取html页面的问题，简单的说。

读取 html到DOM ,找到tag中span中的id属性，去更改id的属性
debugview中看到更改，但是存为文件，没有更改

该如何写呢？谢谢，代码如下
public void ParserHtmlResource(string path)
{

System.IO.StreamReader sr = new System.IO.StreamReader(path);
string strHtml = sr.ReadToEnd();
mshtml.IHTMLDocument2 mydoc = new mshtml.HTMLDocumentClass();

mydoc.write(strHtml);

foreach (mshtml.IHTMLElement el in (mshtml.IHTMLElementCollection)mydoc.body.all)
{
string tagname = el.tagName;
if (tagname.ToLower() == "span")
{
object nameAttribute = el.getAttribute("id", 0);
if (nameAttribute != null)
{
// mshtml.IHTMLElement3 element = (mshtml.IHTMLElement3)el;
// element.contentEditable = "true";
Random rand = new Random();
int serial = rand.Next(500);
string name = string.Format("unnamedid{0:D}", serial);
el.setAttribute("id", name, 1);
}
}
}
IPersistFile ss = mydoc as IPersistFile;
ss.Save("c:\\cc.html", true);
}

帮顶哦

因为你只是修改了执行后代码，但保存的话并不是保存执行后的代码。
为什么不考虑使用纯文本操作

哈哈.终于解决了啊?

[FAICHEN]

原来这末容易啊

[FAICHEN]

纯文本怎末做？太麻烦了吧~
cast mydoc 之前通过debugview 可以看到body里面的内容已经更改
这句话什莫意思？“保存的话并不是保存执行后的代码“

谢谢阿~

尝试了 IPersistStreamInit 可以保存，但是发现原来cast IHTMLDocument3就可以保存出来了竟然找了半天没找到，特此更新。
public void ParserHtmlResource(string path)
{

System.IO.StreamReader sr = new System.IO.StreamReader(path);
string strHtml = sr.ReadToEnd();
mshtml.IHTMLDocument2 mydoc = new mshtml.HTMLDocumentClass();

mydoc.write(strHtml);

foreach (mshtml.IHTMLElement el in (mshtml.IHTMLElementCollection)mydoc.body.all)
{
string tagname = el.tagName;
if (tagname.ToLower() == "span")
{
object nameAttribute = el.getAttribute("id", 0);
if (nameAttribute != null)
{
// mshtml.IHTMLElement3 element = (mshtml.IHTMLElement3)el;
// element.contentEditable = "true";
Random rand = new Random();
int serial = rand.Next(500);
string name = string.Format("unnamedid{0:D}", serial);
el.setAttribute("id", name, 1);
}
}
}
mshtml.IHTMLDocument3 saveDoc =
(mshtml.IHTMLDocument3)mydoc as mshtml.IHTMLDocument3;
string ss = saveDoc.documentElement.outerHTML;
//outerHTML is updated,save it file

}

剩下的可以散分咯
