DotNet中使用xml相对比较轻松，在vc中操作xml，有些繁琐。最近在网络上得知CMarkup比较好用，于是试了下，还好，就把部分例子写出来。以后有时间的话，再写清楚点。

 

 

//----------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

//----查看所有UserID----
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—

//----查看所有UserID---- 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>

//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

CString strID = _T("");
      CString strPwd = _T("");
      CMarkup xml;
      xml.SetDoc("<?xml version=/"1.0/" encoding=/"UTF-8/"?>");
      xml.AddElem("UserInfo");
      xml.IntoElem();
      for (int i=0; i<10; i++)
      {
              //产生一个随机数，作为权限
              srand(UINT(time(NULL)+i));
              int nLevel = rand()%256;
              strID.Format("UserID%02d",i);
              strPwd.Format("UserPwd%02d",i);
              xml.AddElem("User");
              xml.AddAttrib("UserID",strID);
              xml.AddAttrib("UserPwd",strPwd);
              xml.AddAttrib("UserLevel",nLevel);
      }
      xml.OutOfElem();
      xml.Save("UserInfo1.xml");

CString strID = _T(""); CString strPwd = _T(""); CMarkup xml; xml.SetDoc("<?xml version=/"1.0/" encoding=/"UTF-8/"?>"); xml.AddElem("UserInfo"); xml.IntoElem(); for (int i=0; i<10; i++) { //产生一个随机数，作为权限 srand(UINT(time(NULL)+i)); int nLevel = rand()%256; strID.Format("UserID%02d",i); strPwd.Format("UserPwd%02d",i); xml.AddElem("User"); xml.AddAttrib("UserID",strID); xml.AddAttrib("UserPwd",strPwd); xml.AddAttrib("UserLevel",nLevel); } xml.OutOfElem(); xml.Save("UserInfo1.xml");

 

8. 查找

      if (bLoad)
      {
