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" ?>
