VC轻松解析XML文件 - CMarkup类的使用方法
http://www.cctry.com/thread-3866-1-1.html
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"?> ");
- 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"?> ");
- 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(" ---tagName:%s,Data:%s-- ",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(" ---tagName:%s,Data:%s-- ",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(" ---tagName:%s,Data:%s-- ",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(" ---tagName:%s,Data:%s-- ",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(" ---tagName:%s,Data:%s-- ",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(" ---tagName:%s,Data:%s-- ",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="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="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。
