Qt正则替换

//通过正则表达式替换掉匹配的内容
/*QList::Iterator it = navList.begin(), itend = navList.end();

for (; it != itend; it++) {
    QString strRx("\\|.*");
    QRegExp rxlen(strRx);
    int pos = rxlen.indexIn(*it);

    if (pos > -1) {
        QString value = rxlen.cap(0);
        QString unit = rxlen.cap(1);
    }

    (*it).replace(rxlen, "");
