大家好，这是我在这里的第一个问题。我仍在学习英语，所以请对我温柔...
我是初学者c ++程序员。
我正在尝试制作一个程序，该程序读取xml文件，对某些变量进行一些操作，然后再次写入。
在xml文件中，一行如下所示：
<ItemDef Vnum="194" Name="ܧZы+4" LocalizedName="localizedname+4" Type="1" SubType="0" Weight="0" Size="2" AntiFlags="262188" Flags="1" WearFlags="16" ImmuneFlags="0" Gold="720000" ShopBuyPrice="720000" LimitType0="1" LimitValue0="75" LimitType1="0" LimitValue1="0" ApplyType0="7" ApplyValue0="21" ApplyType1="0" ApplyValue1="0" ApplyType2="0" ApplyValue2="0" Value0="0" Value1="67" Value2="98" Value3="90" Value4="110" Value5="30" Socket0="0" Socket1="0" Socket2="0" RefinedVnum="195" RefineSet="23" AlterToMagicItemPercent="0" Specular="30" GainSocketPercent="3" AddonType="0" />

，我需要对一个或多个信息进行一些操作。像将LimitType0从所有行或+1更改为所有Antiflag号
我该怎么做？到目前为止，这是我的糟糕进展：
using namespace std;
#include <fstream>
#include <iostream>
#include <cmath>
#include <string>
#include <iomanip>
#include <cstring>
int main() {
string name, localizedname;
int Vnum, Type, SubType, Weight, Size, AntiFlags, Flags, WearFlags, ImmuneFlags;
int Gold, ShopBuyPrice, LimitType0, LimitValue0, LimitType1, LimitValue1, ApplyType0;
int ApplyValue0, ApplyType1, ApplyValue1, ApplyType2, ApplyValue2, Value0, Value1;
int Value2, Value3, Value4, Value5, Socket0, Socket1, Socket2, RefinedVnum, RefineSet, AlterToMagicItemPercent, Specular, GainSocketPercent, AddonType;
ofstream yaz("proto_new.xml", ios::app);
ifstream fileread("proto.xml");
while (!fileread.eof()){
//ı dont know what should ı write here...
}
fileread.close();
yourfile.close();
return 0;
}
