C++之map使用

解析文件或者字符串，一key跟keyvalue来存在map中，如下代码：

test.h：

#include <map>
#include <vector>

Class test

{

public:

void list_Map();

private:

map<string,string> pensonnel;
map<string,string>::iterator iter;

}

test.cpp:

void test::list_Map()

{

ifstream infile;
infile.open("D:\\XX.dpi");
char buffer[1024]={0};
int i=0;
int chang_first=0;
int chang_last=0;
int value_first=0;
int value_last=0;
char key_tag[10]={0};
char value_tag[1024]={0};
if (!infile)
{
return false;

}
while (!infile.eof() )
{
infile.getline (buffer,1024);

i = StringFind(buffer,"Name");

if(i!=-1)
{
chang_first = StringFind(buffer,"\"");
chang_last = StringFind(buffer,"Length");
memcpy(key_tag,buffer+chang_first+1,chang_last-2-chang_first-1);
value_first = StringFind(buffer,"\">");
value_last = StringFind(buffer,"</DGI>");
memcpy(value_tag,buffer+value_first+2,value_last-2-value_first);
string key_string(key_tag);
string value_string(value_tag);
cout<<"insert:"<<key_string<<","<<value_string<<endl;
pensonnel.insert(pair<string, string>(key_string, value_string));

}

}
printf("mapsize=%d\n",pensonnel.size());

for(iter=pensonnel.begin();iter !=pensonnel.end();iter++)
{
cout<<i<<":"<<iter->first<<", "<<iter->second<<endl;
}

}

其中文件XX.dpi内容为：

<?xml version="1.0" encoding="GBK" ?>
