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" ?>
