VC轻松解析XML文件 - CMarkup类的使用方法

VC解析XML文件的工具有很多，CMarkup， tinyXML，还有IBM的，MS的等等。
据说tinyXML很好，可能字符集问题，我编译不了。
所以就用CMarkup来解析，使用过后，觉得非常不错，使用起来很方便。
CMarkup下载地址：http://www.firstobject.com/
发现网上有方法很法，我就摘下来了

//----------UserInfo.xml--------------    xml version="1.0" encoding="UTF-8" ?>      <UserInfo>      <UserID>luo</UserID>       <UserID>lin</UserID>       </UserInfo>   //----------UserInfo.xml--------------xml version="1.0" encoding="UTF-8" ?>  <UserInfo> <UserID>luo</UserID>  <UserID>lin</UserID>  </UserInfo>

1. 生成UserInfo.xml

CMarkup xml;     xml.SetDoc("xml version=/"1.0/" encoding=/"UTF-8/"?>/r/n");     xml.AddElem("UserInfo");     xml.IntoElem();     xml.AddElem("UserID","luo");     xml.AddElem("UserID","lin");     xml.OutOfElem();     xml.Save("UserInfo.xml");    CMarkup xml; xml.SetDoc("xml version=/"1.0/" encoding=/"UTF-8/"?>/r/n"); xml.AddElem("UserInfo"); xml.IntoElem(); xml.AddElem("UserID","luo"); xml.AddElem("UserID","lin"); xml.OutOfElem(); xml.Save("UserInfo.xml");

2. 浏览特定元素

CMarkup xml;     xml.Load("UserInfo.xml");     BOOL bFind = true;     xml.ResetMainPos();     while (xml.FindChildElem("UserID");)     {           //此时接点还是父接点             CString strTagName = _T("");             CString strData = _T("");             strTagName = xml.GetChildTagName();             strData = xml.GetChildData();             TRACE("/n---tagName:%s,Data:%s--/n",strTagName,strData);     }           /********************这样也可以******************          CMarkup xml;          xml.Load("UserInfo.xml");          BOOL bFind = true;          xml.ResetMainPos();                   while (xml.FindChildElem("UserID");)          {                        xml.IntoElem();                        CString strTagName = _T("");                        CString strData = _T("");                        strTagName = xml.GetTagName();                        strData = xml.GetData();                        TRACE("/n---tagName:%s,Data:%s--/n",strTagName,strData);                        xml.OutOfElem();          }*/           /**************这样也可以**********************          CMarkup xml;          xml.Load("UserInfo.xml");          BOOL bFind = true;          xml.ResetMainPos();          xml.FindElem();  //UserInfo          xml.IntoElem();          while (xml.FindElem("UserID");)          {                        CString strTagName = _T("");                        CString strData = _T("");                        strTagName = xml.GetTagName();                        strData = xml.GetData();                        TRACE("/n---tagName:%s,Data:%s--/n",strTagName,strData);          }          */

//-------------结果----------
---tagName:UserID,Data:luo--
---tagName:UserID,Data:lin—

CMarkup xml; xml.Load("UserInfo.xml"); BOOL bFind = true; xml.ResetMainPos(); while (xml.FindChildElem("UserID");) {       //此时接点还是父接点         CString strTagName = _T("");         CString strData = _T("");         strTagName = xml.GetChildTagName();         strData = xml.GetChildData();         TRACE("/n---tagName:%s,Data:%s--/n",strTagName,strData); }       /********************这样也可以******************       CMarkup xml;       xml.Load("UserInfo.xml");       BOOL bFind = true;       xml.ResetMainPos();             while (xml.FindChildElem("UserID");)       {                     xml.IntoElem();                     CString strTagName = _T("");                     CString strData = _T("");                     strTagName = xml.GetTagName();                     strData = xml.GetData();                     TRACE("/n---tagName:%s,Data:%s--/n",strTagName,strData);                     xml.OutOfElem();       }*/       /**************这样也可以**********************       CMarkup xml;       xml.Load("UserInfo.xml");       BOOL bFind = true;       xml.ResetMainPos();       xml.FindElem();  //UserInfo       xml.IntoElem();       while (xml.FindElem("UserID");)       {                     CString strTagName = _T("");                     CString strData = _T("");                     strTagName = xml.GetTagName();                     strData = xml.GetData();                     TRACE("/n---tagName:%s,Data:%s--/n",strTagName,strData);       }       */

//-------------结果----------
---tagName:UserID,Data:luo--
---tagName:UserID,Data:lin—

3. 修改

//--------把UserID为”luo”改为”flypigluo”-----------

BOOL bLoadXml = false;     CMarkup xml;     bLoadXml = xml.Load("UserInfo.xml");           if (bLoadXml)           {                   CString strUserID = _T("");                   xml.ResetMainPos();                   xml.FindElem();                   xml.IntoElem();                   while (xml.FindElem("UserID"))                   {                         strUserID = xml.GetData();                         if (strUserID=="luo")                         {                                 xml.SetData(CString("flypig")+strUserID);                                 xml.Save("UserInfo.xml");                                 break;                         }                   }           }    //--------把UserID为”luo”改为”flypigluo”----------- BOOL bLoadXml = false; CMarkup xml; bLoadXml = xml.Load("UserInfo.xml");       if (bLoadXml)       {               CString strUserID = _T("");               xml.ResetMainPos();               xml.FindElem();               xml.IntoElem();               while (xml.FindElem("UserID"))               {                     strUserID = xml.GetData();                     if (strUserID=="luo")                     {                             xml.SetData(CString("flypig")+strUserID);                             xml.Save("UserInfo.xml");                             break;                     }               }       }

4. 添加

4.1 添在最后面（使用的是AddElem）
//加在最后面

BOOL bLoadXml = false;           CMarkup xml;           bLoadXml = xml.Load("UserInfo.xml");           if (bLoadXml)           {                   xml.ResetMainPos();                   xml.FindElem();                   xml.IntoElem();                   xml.AddElem("UserID","luoluo");                   xml.OutOfElem();                   xml.Save("UserInfo.xml");           }     //--------原来为------     xml version="1.0" encoding="UTF-8" ?>     <UserInfo>       <UserID>luo</UserID>       <UserID>lin</UserID>       </UserInfo>     //---------添加后为-------------     xml version="1.0" encoding="UTF-8" ?>     <UserInfo>       <UserID>luo</UserID>       <UserID>lin</UserID>       <UserID>luoluo</UserID>       </UserInfo>

4.2 加在最前面（使用InsertElem）

BOOL bLoadXml = false;     CMarkup xml;     bLoadXml = xml.Load("UserInfo.xml");     if (bLoadXml)     {           xml.ResetMainPos();           xml.FindElem();           xml.IntoElem();           xml.InsertElem("UserID","AddUserIDHead");           xml.OutOfElem();           xml.Save("UserInfo.xml");     }     //----原来为—     xml version="1.0" encoding="UTF-8" ?>     <UserInfo>       <UserID>luo</UserID>       <UserID>lin</UserID>       </UserInfo>     //------修改后-----     xml version="1.0" encoding="UTF-8" ?>     <UserInfo>       <UserID>AddUserIDHead</UserID>       <UserID>luo</UserID>       <UserID>lin</UserID>       </UserInfo>    BOOL bLoadXml = false; CMarkup xml; bLoadXml = xml.Load("UserInfo.xml"); if (bLoadXml) {       xml.ResetMainPos();       xml.FindElem();       xml.IntoElem();       xml.InsertElem("UserID","AddUserIDHead");       xml.OutOfElem();       xml.Save("UserInfo.xml"); } //----原来为— xml version="1.0" encoding="UTF-8" ?> <UserInfo>   <UserID>luo</UserID>   <UserID>lin</UserID>   </UserInfo> //------修改后----- xml version="1.0" encoding="UTF-8" ?> <UserInfo>   <UserID>AddUserIDHead</UserID>   <UserID>luo</UserID>   <UserID>lin</UserID>   </UserInfo>

5. 删除

CMarkup xml;     xml.Load("UserInfo.xml");     BOOL bFind = true;     xml.ResetMainPos();          while (bFind)     {           bFind = xml.FindChildElem("UserID");           if (bFind)           {                   //此时接点还是父接点                   CString strData = _T("");                   strData = xml.GetChildData();                   if (strData=="luo")                   {                         xml.RemoveChildElem();                         xml.Save("UserInfo.xml");                         break;                   }           }     }    CMarkup xml; xml.Load("UserInfo.xml"); BOOL bFind = true; xml.ResetMainPos();      while (bFind) {       bFind = xml.FindChildElem("UserID");       if (bFind)       {               //此时接点还是父接点               CString strData = _T("");               strData = xml.GetChildData();               if (strData=="luo")               {                     xml.RemoveChildElem();                     xml.Save("UserInfo.xml");                     break;               }       } }

6. 查找
见第二点浏览。类似上面的例子里面没有属性这些东西，下面的一个例子是有属性的

//UserInfo1.xml     xml version="1.0" encoding="UTF-8" ?>     <UserInfo>       <User UserID="UserID00" UserPwd="UserPwd00" UserLevel="158" />       <User UserID="UserID01" UserPwd="UserPwd01" UserLevel="162" />       <User UserID="UserID02" UserPwd="UserPwd02" UserLevel="165" />       <User UserID="UserID03" UserPwd="UserPwd03" UserLevel="168" />       <User UserID="UserID04" UserPwd="UserPwd04" UserLevel="171" />       <User UserID="UserID05" UserPwd="UserPwd05" UserLevel="175" />       <User UserID="UserID06" UserPwd="UserPwd06" UserLevel="178" />       <User UserID="UserID07" UserPwd="UserPwd07" UserLevel="181" />       <User UserID="UserID08" UserPwd="UserPwd08" UserLevel="184" />       <User UserID="UserID09" UserPwd="UserPwd09" UserLevel="188" />       </UserInfo>    //UserInfo1.xml xml version="1.0" encoding="UTF-8" ?> <UserInfo>   <User UserID="UserID00" UserPwd="UserPwd00" UserLevel="158" />   <User UserID="UserID01" UserPwd="UserPwd01" UserLevel="162" />   <User UserID="UserID02" UserPwd="UserPwd02" UserLevel="165" />   <User UserID="UserID03" UserPwd="UserPwd03" UserLevel="168" />   <User UserID="UserID04" UserPwd="UserPwd04" UserLevel="171" />   <User UserID="UserID05" UserPwd="UserPwd05" UserLevel="175" />   <User UserID="UserID06" UserPwd="UserPwd06" UserLevel="178" />   <User UserID="UserID07" UserPwd="UserPwd07" UserLevel="181" />   <User UserID="UserID08" UserPwd="UserPwd08" UserLevel="184" />   <User UserID="UserID09" UserPwd="UserPwd09" UserLevel="188" />   </UserInfo>

7. 产生

CMarkup字符集问题
daubwu posted @ 2008年9月08日 00:54 in VC with tags XML CMarkup , 38 阅读
CMarkup支持Unicode，_MBCS宏定义。VS默认设置为MBCS宏定义，未设置该宏时为UTF-8编码。
有 MBCS宏定义，且打开的文件是UTF-8编码：
CMarkup在Load时将UTF-8转换ANSI编码格式，所以要在读取的地方设置

#include <locale.h>setlocale(LC_ALL, "");

没有MBCS宏定义，且打开的文件是UTF-8编码：
系统默认将文件按UTF-8格式读入系统中，所以显示的时候要手动将数据转换为ANSI格式的进行显示

#include <locale.h>setlocale(LC_ALL, "");strVal = CMarkup::UTF8ToA(strVal);

PS：通过strcpy等拷贝函数可以修正
