Qt Read XML File - c++

Question

I am trying to read an xml file in Qt, which I successfully generated using a different method. Here is my xml file:
<?xml version="1.0" encoding="UTF-8"?>
<Project>
<EditorTheme>NULL</EditorTheme>
<Modules>
<Module>
<Name>Module_Renderer</Name>
<Position>471,164</Position>
<Size>200,100</Size>
<Locked>true</Locked>
<Visible>true</Visible>
</Module>
<Module>
<Name>Module_Console</Name>
<Position>200,229</Position>
<Size>256,192</Size>
<Locked>true</Locked>
<Visible>false</Visible>
</Module>
<Module>
<Name>Module_ResourceToolkit</Name>
<Position>1049,328</Position>
<Size>200,100</Size>
<Locked>true</Locked>
<Visible>true</Visible>
</Module>
<Module>
<Name>Module_CellEditor</Name>
<Position>542,564</Position>
<Size>200,100</Size>
<Locked>true</Locked>
<Visible>false</Visible>
</Module>
</Modules>
</Project>
And here is some code that I am using to parse this file:
Project ProjectLoader::loadLastProject( ConsoleModule* console ) {
Project project;
// load xml
QFile file( "C:/Users/Krynn/Desktop/LastProject.xml" );
if( !file.open( QFile::ReadOnly | QFile::Text ) ) {
// print error cannot open
}
QXmlStreamReader reader;
console->outputDisplay->append( "Test" );
reader.setDevice( &file );
reader.readNext();
while( !reader.atEnd() && !reader.hasError() ) {
reader.readNext();
if( reader.isStartElement() ) {
QString name = reader.name().toString();
if( reader.name() == "Project" ) {
reader.readNextStartElement();
if( reader.name().toString() == "EditorTheme" ) {
// Append Project theme
console->outputDisplay->append( "Theme Detected: " + reader.name().toString() + " " + reader.readElementText() );
}
reader.readNextStartElement();
if( reader.name().toString() == "Modules" ) {
// how do I proceed??
console->outputDisplay->append( QString( "" ) + " " + reader.name().toString() + " " + reader.readElementText() );
}
}
}
}
if( reader.hasError() ) {
console->outputDisplay->append( "XML error: " + reader.errorString() );
} else if( reader.atEnd() ) {
console->outputDisplay->append( "End of XML File Reached" );
}
file.close();
return project;
}
And here is some visual output for what that code gives me:
Really, I just don't know how I would go about loading all the module data within the xml file. I was using a plain text file previously to store all this stuff, but now I want to upgrade. Any help would be greatly appreciated.

Nevermind I figured it out.
Project ProjectLoader::loadLastProject( ConsoleModule* console ) {
Project project;
// load xml
QFile file( "C:/Users/Krynn/Desktop/LastProject.xml" );
if( !file.open( QFile::ReadOnly | QFile::Text ) ) {
// print error cannot open
}
QXmlStreamReader reader;
reader.setDevice( &file );
reader.readNext();
int count = 0;
while( !reader.atEnd() ) { //&& !reader.hasError()
reader.readNext();
if( reader.isStartElement() ) {
if( reader.name().toString() == "Module" ) {
WindowModuleSaveData data;
reader.readNextStartElement();
data.name = reader.readElementText(); // name
reader.readNextStartElement();
data.position = convertStringToQPoint( reader.readElementText() );
console->outputDisplay->append( convertQPointToString(data.position) );
reader.readNextStartElement();
data.size = convertStringToQSize( reader.readElementText() );
reader.readNextStartElement();
data.isLocked = reader.readElementText() == "true" ? true : false;
reader.readNextStartElement();
data.isVisible = reader.readElementText() == "true" ? true : false;
project.modules.push_back( data );
console->outputDisplay->append("Loaded A Module");
}
count++;
}
}
console->outputDisplay->append( QString::number( count ) );
if( reader.hasError() ) {
console->outputDisplay->append( "XML error: " + reader.errorString() );
} else if( reader.atEnd() ) {
console->outputDisplay->append( "End of XML File Reached" );
}
file.close();
return project;
}
The above code may be error prone, because it assumes what the next child may be instead of actually testing for it. Good enough for now though.
