我的功能如下：
void VrsRequesterWrapper::parseHardwareData(QString pData)
{
qDebug() << " parseHardwareData ";
QXmlStreamReader reader(pData);
qDebug() << " first Item #1" << reader.name();
if(reader.readNextStartElement())
{
qDebug() << " first Item #2" << reader.name();
while(reader.name() == "unit2") {
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #1 " << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #2" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #3" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #4" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #5" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #6" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #7" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #8" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE #9" << reader.name();
reader.skipCurrentElement();
}
qDebug() << "DATA VALUE #10" << reader.name();
while(reader.readNextStartElement()){
if(reader.name() == "eth_addresses"){
while(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Ethernet #1" << reader.name();
reader.skipCurrentElement();
}
}
}
qDebug() << "DATA VALUE Board while #1" << reader.name();
while(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Board while #2" << reader.name();
if(reader.name() == "boards"){
qDebug() << "DATA VALUE Board while #3" << reader.name();
while(reader.readNextStartElement()) {
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #1" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #2" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #3" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #4" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #5" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #6" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #7" << reader.name();
reader.skipCurrentElement();
}
if(reader.readNextStartElement()) {
qDebug() << "DATA VALUE Boards #8" << reader.name();
reader.skipCurrentElement();
}
}
}
}
}
}
}
然而，我无法完全解析“board”标签..会很好如果我能得到一些提示让它不要。此外，电路板标签的数量可能会有所不同，有些用于eth_addresses，例如，上面示例中的电路板标签为2和3.
答案 0 :(得分：0)
最后我设法解决了它，下面是代码片段。希望它对其他人有用：
