那就把字符串资源放在xml文件中，载入字符串的时候从xml读取
--------------------------------------------------------------------------------
读取xml文件
--------------------------------------------------------------------------------
能给个例子么，你们说的我知道
--------------------------------------------------------------------------------
读写XML文件可用MSXML4
//引入
#import "C:\WINNT.0\system32\msxml4.dll"
//DOM的DOC对象定义
MSXML2::IXMLDOMDocumentPtr   pXMLDoc;
//解析
void CMainFrame::OnParsexmldoc()
{
//加载文件
pXMLDoc->load("c:\\XML\\test.xml");
//在树中查找名为City的节点,"//"表示在任意一层查找
MSXML2::IXMLDOMElementPtr  childNode ;
childNode = (MSXML2::IXMLDOMElementPtr)(pXMLDoc->selectSingleNode("//AUTHOR"));
//得到节点类型
MSXML2::DOMNodeType nodeType;
childNode->get_nodeType(&nodeType);
//节点名称
BSTR var;
CString name;
childNode->get_nodeName(&var);
name = (char*)(_bstr_t)var;
//节点值
VARIANT varVal;
childNode->get_nodeTypedValue(&varVal);
CString strValue = (char*)(_bstr_t)varVal;
//节点属性,放在链表中
MSXML2::IXMLDOMNamedNodeMapPtr pAttrs = NULL;
MSXML2::IXMLDOMNodePtr pAttrItem;
childNode->get_attributes(&pAttrs);
long nCount ;
pAttrs->get_length(&nCount);
for(int i = 0 ; i < nCount ; i++)
{                
pAttrs->get_item(i,&pAttrItem);
//我们可以通过函数get_nodeName,get_nodeTypedValue得到属性名和属性值
//也可以直接得到
CString strAttrName   = (char*)(_bstr_t)pAttrItem->nodeName;
CString strAttrValue  = (char*)(_bstr_t)pAttrItem->nodeTypedValue;
}
}
//创建
void CMainFrame::OnCreatexmldoc()
{
MSXML2::IXMLDOMElementPtr  xmlRoot;
 //根节点的名称为china
    pXMLDoc->raw_createElement((_bstr_t)(char*)"china", &xmlRoot);
//MSXML2::IXMLDOMNamedNodeMapPtr pAttrs = NULL;
//pAttrs->length=2;
//xmlRoot->raw_setAttributeNode(
//xmlRoot->setAttributeNode(attributes.setAttribute("fengjie","fengjie test root attribute");
xmlRoot->setAttribute("fengjie","ddd test root attribute");
pXMLDoc->raw_appendChild(xmlRoot, NULL);
MSXML2::IXMLDOMElementPtr  childNode ;        
pXMLDoc->raw_createElement((_bstr_t)(char*)"City:dd", &childNode);
childNode->Puttext("WuHan");//节点值
childNode->setAttribute("population","8,000,000");//属性名,属性值
childNode->setAttribute("area","10000");
xmlRoot->appendChild(childNode);
pXMLDoc->raw_createElement((_bstr_t)(char*)"City:xx", &childNode);
childNode->Puttext("ShangHai");
childNode->setAttribute("population","12,000,000");
childNode->setAttribute("area","12000");
xmlRoot->appendChild(childNode);
//保存到文件
//如果不存在就建立,存在就覆盖
pXMLDoc->save("c:\\XML\\he.xml");
}

]]>使用CMarkUp解析XMLhttp://www.cppblog.com/ipuerta/archive/2008/11/08/66294.htmlIPIPFri, 07 Nov 2008 18:04:00 GMThttp://www.cppblog.com/ipuerta/archive/2008/11/08/66294.htmlhttp://www.cppblog.com/ipuerta/comments/66294.htmlhttp://www.cppblog.com/ipuerta/archive/2008/11/08/66294.html#Feedback0http://www.cppblog.com/ipuerta/comments/commentRss/66294.htmlhttp://www.cppblog.com/ipuerta/services/trackbacks/66294.htmlhttp://www.firstobject.com/dn_markupmethods.htm

学习笔记

在一个目录下的搜索，即FindElem（）不分先后出现顺序。

(一) 先讲一下XML中的物殊字符，手动填写时注意一下。

字符                  字符实体
&                          &amp;或&
'                          &apos;或'
>                          &gt;或>
<                          &lt;或&<
"                      &quot;或"


(二) CMarkup类的源代码。

这是目前的最新版本；

这是官网示例文件，取出里面的Markup.cpp和Markup.h，导入你的工程里面，CMarkup类就可以用了；

下载地址：http://www.firstobject.com/Markup90.zip


(三) 创建一个XML文档。

CMarkup xml;
xml.AddElem( "ORDER" );
xml.AddChildElem( "ITEM" );
xml.IntoElem();
xml.AddChildElem( "SN", "132487A-J" );
xml.AddChildElem( "NAME", "crank casing" );
xml.AddChildElem( "QTY", "1" );
xml.Save("c:\\UserInfo.xml");

效果如下：

<ORDER>
<ITEM>
<SN>132487A-J</SN>
<NAME>crank casing</NAME>
<QTY>1</QTY>
</ITEM>
</ORDER>
(四) 浏览特定元素
CMarkup xml;
xml.Load("UserInfo.xml");
while ( xml.FindChildElem("ITEM") )
{
          xml.IntoElem();
          xml.FindChildElem( "SN" );
          CString csSN = xml.GetChildData();
          xml.FindChildElem( "QTY" );
    int nQty = atoi( xml.GetChildData() );
          xml.OutOfElem();
}
(五)增加元素和属性
添加在最后面,使用的是AddElem;添加在最前面,使用InsertElem。
CMarkup xml;
xml.Load("c:\\UserInfo.xml");
xml.AddElem( "ORDER" );
xml.IntoElem(); // 进入 ORDER



          xml.AddElem( "ITEM" );
          xml.IntoElem(); // 进入 ITEM
          xml.AddElem( "SN", "4238764-A" ); //添加元素
          xml.AddElem( "NAME", "bearing" );//添加元素
          xml.AddElem( "QTY", "15" );//添加元素
          xml.OutOfElem(); // 退出 ITEM 
xml.AddElem( "SHIPMENT" );
xml.IntoElem(); // 进入 SHIPMENT
xml.AddElem( "POC" );//添加元素
xml.SetAttrib( "type", "non-emergency");//添加属性
xml.IntoElem(); // 进入 POC
xml.AddElem( "NAME", "John Smith");//添加元素
xml.AddElem( "TEL", "555-1234");//添加元素
xml.Save("c:\\UserInfo.xml");

效果如下：

<ORDER>
<ITEM>
<SN>132487A-J</SN>
<NAME>crank casing</NAME>
<QTY>1</QTY>
</ITEM>
<ITEM>
<SN>4238764-A</SN>
<NAME>bearing</NAME>
<QTY>15</QTY>
</ITEM>
<SHIPMENT>
<POC type="non-emergency">
<NAME>John Smith</NAME>
<TEL>555-1234</TEL>
</POC>
</SHIPMENT>
</ORDER>

(六) 修改元素和属性

如将POC中的属性type改成：change;

元素TEL改成：123456789

           CMarkup xml;
if (xml.Load("UserInfo.xml"))
{
      CString strUserID = _T("");
      xml.ResetMainPos();
      if (xml.FindChildElem("SHIPMENT"))
      {
       xml.IntoElem();
       if (xml.FindChildElem("POC"))
       {
        xml.IntoElem();
        CString str_type=xml.GetAttrib("type");
        MessageBox(str_type);
        xml.SetAttrib("type","change");
        strUserID = xml.GetData();
    
        if (xml.FindChildElem("TEL"))
        {
         xml.IntoElem();
         xml.SetData("123456789");
         xml.Save("UserInfo.xml");
         return;
        }
       }
      }
}

(七)删除元素：

删除SN=132487A-J的项目。

CMarkup xml;
if (xml.Load("UserInfo.xml"))
{
      CString strUserID = _T("");
      xml.ResetMainPos();
      if (xml.FindChildElem("ITEM"))
      {
       xml.IntoElem();
       CString str_sn;
       xml.FindChildElem("SN");
       str_sn=xml.GetChildData();
       if(str_sn=="132487A-J")
       {
        xml.RemoveElem();
        xml.Save("UserInfo.xml");
       }
      }
}

]]>用CMarkup类操纵XML http://www.cppblog.com/ipuerta/archive/2008/11/08/66293.htmlIPIPFri, 07 Nov 2008 18:01:00 GMThttp://www.cppblog.com/ipuerta/archive/2008/11/08/66293.htmlhttp://www.cppblog.com/ipuerta/comments/66293.htmlhttp://www.cppblog.com/ipuerta/archive/2008/11/08/66293.html#Feedback0http://www.cppblog.com/ipuerta/comments/commentRss/66293.htmlhttp://www.cppblog.com/ipuerta/services/trackbacks/66293.htmlhttp://www.firstobject.com/下载CMarkup教学版，解压后里面是一个DEMO，将Markup.h .cpp拷贝并添加到工程中，第一次编译可能会出现预编译错误，解决的方法在Markup.cpp最前面include "stdafx.h"，或者关闭预编译。
　　以下转自http://www.sqlite.com.cn/MySqlite/12/211.Html
//----------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");

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—

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;

}

}

}

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>

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;

}

}

}

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>

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");

8。查找
CMarkup xml;
BOOL bLoad = false;
BOOL bFind = false;
bLoad = xml.Load("UserInfo1.xml");

if (bLoad)
{

CString strID;
CString strPwd;
xml.ResetMainPos();
xml.FindElem(); //UserInfo
while (xml.FindChildElem("User"))
{

strID = xml.GetChildAttrib("UserID");
strPwd = xml.GetChildAttrib("UserPwd");
TRACE("\n----id:%s,pwd:%s-------\n",strID,strPwd);

 

if (strID=="UserID00"&&strPwd=="UserPwd00")
{

bFind = true;
break;

}

}

}

 

if (bFind)
{

TRACE("\n---- find------\n");
}
else
{

TRACE("\n----no find------\n");
}

9。修改
CMarkup xml;
BOOL bLoad = false;
BOOL bFind = false;
bLoad = xml.Load("UserInfo1.xml");

if (bLoad)

{

CString strID;
CString strPwd;

xml.ResetMainPos();
xml.FindElem(); //UserInfo

while (xml.FindChildElem("User"))

{

strID = xml.GetChildAttrib("UserID");
strPwd = xml.GetChildAttrib("UserPwd");
TRACE("\n----id:%s,pwd:%s-------\n",strID,strPwd);

if (strID=="UserID00"&&strPwd=="UserPwd00")
{

bFind = true;
xml.SetChildAttrib("UserID",strID+CString("Modify"));
xml.Save("UserInfo1.xml");
break;

}

}

}

if (bFind)
{

TRACE("\n---- find------\n");
}
else
{

TRACE("\n----no find------\n");
}
