本文用于提取本地网页的标签元素如,,...的内容，非常实用于批量文件的操作，这是按一般文件进行文本查找替换无法比拟的，,而这是使用TWEBBROWSER控件无法做到的。类似的，你可以把本地的HTML文件转换成MHT文件（这是个大家觉得很棘手的问题，本人已经搞定)。

//uses activex,mshtml

function Html_GetTitleFromFile(const HtmlFile:TFileName;var FileTitle:String):Boolean;varIdoc : IHtmlDocument2;//ElementGroup : IhtmlElementCollection;//HtmlItem: IHTMLElement;PersistFile: IPersistFile;beginResult:=False;if not fileexists(HtmlFile) thenexit; FileTitle:='';

try Idoc := CreateComObject(Class_HTMLDOcument) as IHTMLDocument2; PersistFile := IDoc as IPersistFile; if PersistFile.Load(StringToOleStr(HTMLFile),1)<>S_OK then exit; IDoc.designMode := 'on'; //This will disable script execution. { while IDoc.readyState <> 'complete' do //if it dead here,how to do it? begin application.ProcessMessages; end; } // Showmessage(IDoc.readyState); Application.ProcessMessages; sleep(1000); // Showmessage(IDoc.readyState); if IDoc.readyState<>'complete' then begin Application.ProcessMessages; sleep(1000); end; if IDoc.readyState<>'complete' then begin IDoc:=nil; Result:=False; exit; end; Result:=True; FileTitle:=IDoc.title; { //This code also works ElementGroup:=IDoc.all.tags('TITLE') As IhtmlElementCollection; HtmlItem:=ElementGroup.item(0,0) As IHtmlElement; FileTitle:=HtmlItem.innerText; }

finally IDoc := nil; end;end;
