先下載下傳TinyXML,百度一下就行,下載下傳下來解壓,裡面有2個頭檔案和4個cpp檔案,一起加到工程裡面,如圖所示

xmlTest.cpp是包含主函數的檔案,下面直接上代碼,很簡單,不管怎麼樣,總算是實作了,雖然題目要求不使用外加類庫實作,過段時間等題解出來我再上來更新不加外庫實作的方法。
<School name="軟體學院">
<Class name = "C++">
<Student name="tinyxml" number="123">
<email>[email protected]</email>
<address>中國</address>
</Student>
<Student name="jsoncpp" number="456">
<email>[email protected].com</email>
<address>美國</address>
</Student>
</Class>
</School>
//以上是要讀取xml檔案,下面的是xmlTest.cpp。
#include <iostream>
#include "tinystr.h"
#include "tinyxml.h"
#include <string>
using namespace std;
void readSchoolXml() {
using namespace std;
const char * xmlFile = "school.xml";
TiXmlDocument doc;
if (doc.LoadFile(xmlFile)) {
doc.Print();
} else {
cout << "can not parse school.xml" << endl;
return;
}
TiXmlElement* rootElement = doc.RootElement(); //School元素
TiXmlElement* classElement = rootElement->FirstChildElement(); // Class元素
TiXmlElement* studentElement = classElement->FirstChildElement(); //Students
for (; studentElement != NULL; studentElement = studentElement->NextSiblingElement() ) {
TiXmlAttribute* attributeOfStudent = studentElement->FirstAttribute(); //獲得student的name屬性
for (;attributeOfStudent != NULL; attributeOfStudent = attributeOfStudent->Next() ) {
cout << attributeOfStudent->Name() << " : " << attributeOfStudent->Value() << std::endl;
}
TiXmlElement* studentContactElement = studentElement->FirstChildElement();//獲得student的第一個聯系方式
for (; studentContactElement != NULL; studentContactElement = studentContactElement->NextSiblingElement() ) {
string contactType = studentContactElement->Value();
string contactValue = studentContactElement->GetText();
cout << contactType << " : " << contactValue << std::endl;
}
}
int main(){
readSchoolXml();
system("pause");
return ;
}
運作結果如下
