c++ - Qt Read XML File -

i trying read xml file in qt, generated using different method. here 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 code using parse 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 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 visual output code gives me:

really, don't know how go loading module data within xml file. using plain text file store stuff, want upgrade. appreciated.

nevermind figured 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 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 error prone, because assumes next child may instead of testing it. enough though.
