感觉做的方法不好，仅用于备份，仅供参考！

不多说了，直接上代码！

#include <iostream>using namespace std;#define M 10int dataLength = 0;struct NODE{char strTag[100];char strLen[100];char strVale[100];bool isNoLen;int value;}nodeData[M];int GetNumLength(char *ppstr){char*pstr = strdup(ppstr);if(pstr==NULL)return 0;int num1 = 0;int num2 = 0;char *pSaveStr = strtok(pstr,",");while(pSaveStr!=NULL){sscanf(pSaveStr,"%x",&num2);num1 *= (16*16);num1 += num2;pSaveStr = strtok(NULL,",");}delete pstr;return num1;}bool GetMsg(char *pstr){while(pstr!=NULL){char *pSavest1 = pstr+30;if(*pSavest1 == '\0')return false;strncpy(nodeData[dataLength].strTag, pstr, 19);strncpy(nodeData[dataLength].strLen, pstr+20, 9);int nunLength = GetNumLength(nodeData[dataLength].strLen);if(nunLength!=0)nodeData[dataLength].isNoLen = false;else nodeData[dataLength].isNoLen = true;strncpy(nodeData[dataLength].strVale, pstr+30, nunLength*5);nodeData[dataLength].value = GetNumLength(nodeData[dataLength].strVale);pstr=pSavest1+nunLength*5;dataLength++;if(*pstr=='\0')return true;}return true;}void PaiXu(){for (int i=0; i<dataLength; i++){for (int j=i+1; j<dataLength; j++){if(nodeData[i].value<nodeData[j].value)//sawp{struct NODE dateTemp;memcpy(&dateTemp, &nodeData[i], sizeof(struct NODE));memcpy(&nodeData[i], &nodeData[j], sizeof(struct NODE));memcpy(&nodeData[j], &dateTemp, sizeof(struct NODE));}}}}void main(){char strInput[1000] = {'\0'};memset(nodeData, '\0', M*sizeof(struct NODE));cin>>strInput;if(!GetMsg(strInput)){cout<<"false"<<endl;return;}PaiXu();for (int i=0; i<dataLength; i++){cout<<nodeData[i].strTag<<","<<nodeData[i].strLen;if(i!=dataLength-1) //no endif(nodeData[i].isNoLen)//no lengthcout<<",";elsecout<<","<<nodeData[i].strVale<<",";elseif(!nodeData[i].isNoLen)cout<<","<<nodeData[i].strVale;}cout<<endl;}
