由于项目需要现学现卖先将下面两个例子来记录一下。
示例1
直接上代码创建xml文件。
void Config::createServerInfoFile()
{QString strPath 路径;//这里的路径是将要创建的xml的完整路径包含文件名xxx.xmlQFile file(strPath);if (!file.open(QIODevice::WriteOnly | QIODevice::Truncate)) {//之前的内容被清空qDebug()QStringLiteral(打开)strPathQStringLiteral(文件失败);return;}QDomDocument doc;QDomProcessingInstruction processInstruction doc.createProcessingInstruction(xml,version\1.0\ encoding\UTF-8\);doc.appendChild(processInstruction);QDomElement root doc.createElement(server);doc.appendChild(root);QDomElement server1 doc.createElement(helperIp);QDomText server1Text doc.createTextNode(127.0.0.1);server1.appendChild(server1Text);root.appendChild(server1);QDomElement port1 doc.createElement(sendPort);QDomText port1Text doc.createTextNode(9999);port1.appendChild(port1Text);root.appendChild(port1);QDomElement port11 doc.createElement(receviePort);QDomText port11Text doc.createTextNode(9000);port11.appendChild(port11Text);root.appendChild(port11);QDomElement server2 doc.createElement(kserver);QDomText server2Text doc.createTextNode(192.168.1.5);server2.appendChild(server2Text);root.appendChild(server2);QDomElement port2 doc.createElement(kPort);QDomText port2Text doc.createTextNode(9080);port2.appendChild(port2Text);root.appendChild(port2);QDomElement upScreenServer doc.createElement(upServer);QDomText upScreenServerText doc.createTextNode(192.168.1.2);upScreenServer.appendChild(upScreenServerText);root.appendChild(upScreenServer);QDomElement upScreenPort doc.createElement(upPort);QDomText upScreenPortText doc.createTextNode(7999);upScreenPort.appendChild(upScreenPortText);root.appendChild(upScreenPort);QTextStream outFile(file);doc.save(outFile,4);//缩进4格file.close();
}创建的xml文件的内容如下
?xml version1.0 encodingUTF-8?
serverhelperIp127.0.0.1/helperIpsendPort8900/sendPortreceviePort9666/receviePortkserver127.0.0.1/kserverkPort9080/kPortupServer127.0.0.1/upServerupPort7999/upPort
/server下面是示例2两个示例是一样的若看完示例1已经明白大致怎么创建此时就不需要看示例二了。 示例2
const QString strKvmConfigFileName /kvmSeatSources.xml;QString Config::getExeFilePath()
{QString strPath QCoreApplication::applicationDirPath();return strPath;
}void Config::createKvmSeatSourceFile()
{QString strPath getExeFilePath();strPath strKvmConfigFileName;QFile file(strPath);if (!file.open(QIODevice::WriteOnly | QIODevice::Truncate)) {//之前的内容被清空qDebug()QStringLiteral(打开)strPathQStringLiteral(文件失败);return;}QDomDocument doc;QDomProcessingInstruction processInstruct doc.createProcessingInstruction(xml,version\1.0\ encoding\UTF-8\);doc.appendChild(processInstruct);QDomElement root doc.createElement(kvm);doc.appendChild(root);//创建第一个子节点QDomElement firstElement doc.createElement(seatInfo);root.appendChild(firstElement);for (int i 0; i 12; i) {QDomElement seatElement doc.createElement(seat);firstElement.appendChild(seatElement);QDomElement sidElement doc.createElement(sid);QDomText sidText doc.createTextNode(12);sidElement.appendChild(sidText);seatElement.appendChild(sidElement);QDomElement seatNameElement doc.createElement(seatName);QDomText seatNameText doc.createTextNode(admin1);seatNameElement.appendChild(seatNameText);seatElement.appendChild(seatNameElement);QDomElement seatIdElement doc.createElement(seatId);QDomText seatIdText doc.createTextNode(12289832899desa);seatIdElement.appendChild(seatIdText);seatElement.appendChild(seatIdElement);QDomElement seatIpElement doc.createElement(seatIp);QDomText seatIpText doc.createTextNode(192.168.1.20);seatIpElement.appendChild(seatIpText);seatElement.appendChild(seatIpElement);}//创建第二个子节点QDomElement secondElement doc.createElement(signalsource);root.appendChild(secondElement);for (int i 0; i 12; i) {QDomElement sourceElement doc.createElement(source);secondElement.appendChild(sourceElement);QDomElement uidElement doc.createElement(uid);QDomText uidText doc.createTextNode(QString::number(i1));uidElement.appendChild(uidText);sourceElement.appendChild(uidElement);QDomElement ipElement doc.createElement(ip);QDomText ipText doc.createTextNode(192.168.1.2);ipElement.appendChild(ipText);sourceElement.appendChild(ipElement);}QTextStream outStream(file);doc.save(outStream,4);file.close();
}生成的文件的内容
?xml version1.0 encodingUTF-8?

/kvm以上是怎么生成xml文件可能文件的某些字段的值对不上是因为后期手动修改了不影响xml文件的生成理解其意便可。
