代码如下：

       QString filename = QFileDialog::getSaveFileName( this, "Save", "", "*.xml" );

       QFile file( filename );
       if( !file.open(QIODevice::WriteOnly | QIODevice::Text) )
       {
           return;
       }

       QDomDocument document;

       QString strHeader( "version=\"1.0\" encoding=\"UTF-8\"" );
       document.appendChild( document.createProcessingInstruction("xml", strHeader) );

       QDomElement   root_elem = document.createElement( "items" );
       root_elem.setAttribute( "id", 1 );
       document.appendChild( root_elem );

       QDomElement item1 = document.createElement( "item" );
       item1.setAttribute( "src", "<>" );
       item1.setAttribute( "dst", "<>" );
       root_elem.appendChild( item1 );

       QDomElement item2 = document.createElement( "item" );
       item2.setAttribute( "src", ""'&" );
       item2.setAttribute( "dst", "\"'&" );
       root_elem.appendChild( item2 );

       QDomElement item3 = document.createElement( "item" );
       item3.setAttribute( "src", tr("测试数据") );
       item3.setAttribute( "dst", tr("一二三四") );
       root_elem.appendChild( item3 );

       QTextStream out( &file );
       document.save( out, 4 );
       file.close();
