C++学习之 tinyxml库的应用解析xml文件
来源：互联网 发布：播音员录音软件 编辑：程序博客网 时间：2024/05/14 14:02
我的辅导员，又给我了我一个任务，上个星期五给我的任务，昨天就做完了，因为周末去了深圳，周一的时间才弄出来。先介绍一下我的主要工作内容，主要是利用C++对一个xml文档进行解析，将里边的内容放入一个结构体中，然后根据参数进行一级级的查找到所要得到数据。这里肯定是要用到map的了。以后也会利用这个工具进行工作。
首先，我找了一些资料，比较一下发现利用tinyxml这个插件是比较好的，因为它很轻量级。操作很方便。功能很齐全。还是佩服前人技术高手啊。努力我也写一个像这样的库。
首先上一下xml文档吧。这个xml很长，结构很复杂。所以我对这个xml摸索了一段时间，而且利用tinyxml对其进行操作也很麻烦啊。

简单介绍一些tinyxml库所对应的一些重要方法吧：
在TinyXML中，根据XML的各种元素来定义了一些类：
TiXmlBase：整个TinyXML模型的基类。
TiXmlAttribute：对应于XML中的元素的属性。
TiXmlNode：对应于DOM结构中的节点。
TiXmlComment：对应于XML中的注释。
TiXmlDeclaration：对应于XML中的申明部分，即<？versiong="1.0" ?>。
TiXmlDocument：对应于XML的整个文档。
TiXmlElement：对应于XML的元素。
TiXmlText：对应于XML的文字部分。
TiXmlUnknown：对应于XML的未知部分。
TiXmlHandler：定义了针对XML的一些操作。
想要健壮地读取一个XML文档，检查方法调用后的返回值是否为null是很重要的。一种安全的检错实现可能会产生像这样的代码：
TiXmlElement* root = document.FirstChildElement( "Document" );if ( root ){TiXmlElement* element = root->FirstChildElement( "Element" );if ( element ){TiXmlElement* child = element->FirstChildElement( "Child" );if ( child ){TiXmlElement* child2 = child->NextSiblingElement( "Child" );if ( child2 ){// Finally do something useful
然后观察他的文档结构。我变形成了三个结构体，如下：cluster.h
#include <map>#include <string>using namespace std;struct s_msg{public:string SCHEMACODE;string PACKAGENAME;string SCHEMANAME;};struct s_code{public://20000001033775string SCHEMACODE;map<string,s_msg> map_msg;};struct s_bran{public:string CODE;//1map<string,s_code> map_PACKAGEMSG;};
定义成这样的结构体，主要是因为我要找到 s_msg 的内容 通过 GZ，然后还有code 差到下一册，然后再通过SCHEMACODE 再找到下一层进行查找。
下面在给出主要函数的实现。
//// XMLParse_test_3_using_LoadFile.cpp : 定义控制台应用程序的入口点。//#include "stdafx.h"#include <iostream>#include <fstream>#include <map>#include "tinyxml.h"#include "tinystr.h"#include "Cluster.h"using namespace std; s_msg msg; s_code code; s_bran bran;s_BRANCHCODE branch;map<string,s_bran> map_BRANCHCODE; //map<string,s_msg> map_msg; //map<string,s_code> map_PACKAGEMSG; map<string,s_bran> getXmlContent() {// map<string,msg> mes_map;// map<string,s_code> code_map; //map<string,code_map> branch_map; string fileXml = "ClusterPackage.xml"; TiXmlDocument doc( fileXml.c_str() ); doc.LoadFile(); if ( !doc.Parse( fileXml.c_str() ) ) { cout << doc.ErrorDesc() << endl; } //一下将是对每个节点进行解析come on const TiXmlElement *root = doc.RootElement(); cout << endl << " The root element is : " << root->Value() << endl << endl; const TiXmlElement *childElement=root->FirstChildElement(); // for ( const TiXmlNode *child = root->FirstChild(); child; child = child->NextSibling() ) { //cout<<child->Value()<<endl;//BRANCH const TiXmlElement *brn=child->FirstChildElement();//cout<<brn->FirstChild()->Value()<<endl;// 输出的是GZstring str_branchecode=brn->FirstChild()->Value(); //const TiXmlElement *secRoot=child->FirstChildElement(); //cout<<secRoot->Value()<<endl;//BRANCHCODE brn = brn->NextSiblingElement();// cout<<brn->Value() << endl ;//BRANDS //BRAND for (const TiXmlElement *child2=brn->FirstChildElement();child2;child2=child2->NextSiblingElement()) { //child2->FirstChild();//code const TiXmlElement *pCodeNode = child2->FirstChildElement();// cout<<pCodeNode->Value() << " : " << pCodeNode->GetText() ; //code值 //cout<<endl; const TiXmlElement *packageNode=pCodeNode->NextSiblingElement();// cout<<packageNode->Value()<<endl;//PACKAGEMSG for (const TiXmlElement *child3=packageNode->FirstChildElement();child3;child3=child3->NextSiblingElement()) { // const TiXmlElement *msgNode=child3->FirstChildElement();// cout<<msgNode->FirstChild()->Value()<<endl; //20000001033775 msg.SCHEMACODE=msgNode->FirstChild()->Value(); const TiXmlElement *PACKAGENAMEnode=msgNode->NextSiblingElement();// cout<<PACKAGENAMEnode->GetText()<<endl; msg.PACKAGENAME=PACKAGENAMEnode->GetText(); const TiXmlElement *SCHEMANAMEnode=PACKAGENAMEnode->NextSiblingElement();// cout<<SCHEMANAMEnode->GetText()<<endl; msg.SCHEMANAME=SCHEMANAMEnode->GetText();// map_msg[msg.SCHEMACODE]=msg; code.SCHEMACODE=msg.SCHEMACODE; code.map_msg[code.SCHEMACODE]=msg; }bran.CODE=pCodeNode->GetText();//code 做为key，//cout<<bran.CODE<<endl;bran.map_PACKAGEMSG[bran.CODE]=code; }//这个是放到一个结构体内的。//branch.BRANCHCODE=brn->FirstChild()->Value();//GZ KEY//branch.map_BRANCHCODE[branch.BRANCHCODE]=bran;//直接放到map内// cout<<child->FirstChildElement()->Value()<<endl;map_BRANCHCODE[str_branchecode]=bran; } return map_BRANCHCODE; }int find_MSG(string BRANCHCODE,string CODE,string SCHEMACODE , s_msg& msg){map<string,s_bran> a_bran=getXmlContent();map<string,s_bran>::iterator iterBran= a_bran.find(BRANCHCODE);if (iterBran != a_bran.end()){s_bran& re_bran = iterBran->second;map<string,s_code>::iterator itercode =re_bran.map_PACKAGEMSG.find(CODE);if (itercode!=re_bran.map_PACKAGEMSG.end()){s_code& re_code=itercode->second;map<string,s_msg>:: iterator itermsg=re_code.map_msg.find(SCHEMACODE);if (itermsg!=re_code.map_msg.end()){msg=itermsg->second;return 0;}else{cout<<"无此号"<<endl;return -1;}}else{cout<<"无此编号"<<endl;return -1;}return 0;}else{cout<<"没有该城市"<<endl; return -1;}}int _tmain(int argc, _TCHAR* argv[]){string BRANCHCODE;string CODE;string SCHEMACODE;cout<<"请输入一下参数："<<endl;cout<<"BRANCHCODE:";cin>>BRANCHCODE;cout<<"CODE:";cin>>CODE;cout<<"SCHEMACODE:";cin>>SCHEMACODE;s_msg l_msg;find_MSG(BRANCHCODE,CODE,SCHEMACODE,l_msg);return 0;}
呵呵，主要是两个实现方法一个是对xml进行解析，将其放入到一个map对象中，就是一个一个映射的关系，加入到这些。
