Qt 生成 xml 文件

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", "&quot;&apos;&amp;" );
	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();

生成的 xml 文件为：
