import QtQuick 2.0
import QtQuick.XmlListModel 2.0
XmlListModel {
id: xmlModel
source: "http://www.mysite.com/feed.xml"
query: "/rss/channel/item"
XmlRole { name: "title"; query: "title/string()" }
XmlRole { name: "pubDate"; query: "pubDate/string()" }
}
qml里面比较方便 qt里面 好像只有qxmlquery

#include "xqueryratereader.h"

#include "currency.h"
// Notes: my biggest issue with this design is that the different pieces of
//each rate are pulled out separately. I would prefer one query that
//pulled them out in sets.
void readRatesUsingXQuery(const QFileInfo file) {
const QString queryUrl = QString("doc('%1')//rate/%2/string()").arg(file.absoluteFilePath());
typedef QPair QueryPair;
QList queries;
QStringList from, to, conversion;
queries

艾特我了。。。不过我不懂，不好意思
瞥了一眼，楼上用了QtXmlPatterns，这玩意被Qt弃用了。。。。
