Qt 使用QDomDocument读取xml文件_qt读取xml文件

一、错误原因

尽管加入各种dom的头文件还是没用

#include <QMainWindow>
#include <QtXml/QDomDocument>
#include <QtXml/QDomComment>
#include <QtXml/QDomElement>
#include <QTreeWidgetItem>

二、解决办法

QT       += core gui
QT       += xml

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

# The following define makes your compiler emit warnings if
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler).
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
