QT xml文件转化lua table文件 工具

经过两天的奋战，xml 文件 转化为lua table 的工具终于搞成了。

先上代码：

xmltoluatool.h

#ifndef XMLTOLUATOOL_H
#define XMLTOLUATOOL_H

#include <QtWidgets/QMainWindow>
#include "qdom.h"
#include "ui_xmltoluatool.h"

class XmlToLuaTool : public QMainWindow
{

public:

~XmlToLuaTool();
private:

QString inPath;
QString outPath;
QList<QFileInfo> *xmlFileInfo;
QFile *sourcefile;
QString sourceData;
QString desData;
QString desTableName;
QString log;
bool result;
private slots:
void selectXmlDir();
void selectluaDir();
bool makeLuaFiles();
private:

bool XmlToLuaTool::parseXml(QString file_name);
QString makeLuaString(QString str);
bool writeContentToFile(QString str,QString fileName);
};

#endif // XMLTOLUATOOL_H

代码已经测试通过，用QT 做的UI，有不对的地方请大家多多指教。
