plist文件保存有两种方式，一种是正常的像xml一样保存的，一种是二进制保存的。二进制的文件头有bplist00这个关键字。这两种文件libplist都能解析出来。

// ReadPlist.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <Windows.h>
#include <stdio.h>
#include <plist/plist.h>

#pragma comment(lib, "libplist.lib")
int main(int argc, char* argv[])
{
 char file_name[MAX_PATH] = {0};

 char *data = NULL;

 plist_t pl = NULL;

 FILE *fp = NULL;

 int file_len = 0;

 char *p_data = NULL;
 unsigned __int32 p_len = 0;

 printf("请输入文件名：");

 scanf("%s", file_name);

 fp = fopen(file_name, "rb");
 if(!fp)
  goto _out;

 fseek(fp, 0, SEEK_END);
 file_len = ftell(fp);
 fseek(fp,0,SEEK_SET);

 data = (char*)malloc(file_len);
 if(!data)
  goto _out;

 fread(data, 1, file_len, fp);

 if(memcmp(data, "bplist00", 8))
 {
  printf("%s n", data);
 }
 else
 {
  plist_from_bin(data, file_len, &pl);
  plist_to_xml(pl, &p_data, &p_len);
  printf("%s n", p_data);
 }

 system("pause");

_out:
 if(fp)
  fclose(fp);
 if(pl)
  plist_free(pl);
 if (p_data)
  free(p_data);
 if(data)
  delete []data;

 return 0;
} 

需要注意的是libplist解析出来是utf-8编码的
