A little help here with QtNetwork

  • I'm writing a program that customers get tax information from a web portal., I give them a part of my code:

    @void RIF::replyFinished(QNetworkReply *reply)
    QByteArray data = reply->readAll();
    QString str(data);
    qDebug() << str;

    void RIF::on_queryButton_clicked()
    QNetworkAccessManager manager = new QNetworkAccessManager(this);
    connect(manager, SIGNAL(finished(QNetworkReply
    this, SLOT(replyFinished(QNetworkReply*)));

    manager->get(QNetworkRequest(QUrl("http://somepage.com/getrif?rif=" + RIF::_rif())));


    which I get the following information:

    @"<?xml version="1.0" encoding="ISO-8859-1"?>
    <rif:Rif xmlns:rif="rif" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" rif:numeroRif="V1X5XX60XX">rif:NombreCUSTOMER NAME</rif:Nombre>rif:AgenteRetencionIVANO</rif:AgenteRetencionIVA>rif:ContribuyenteIVASI</rif:ContribuyenteIVA>rif:Tasa75</rif:Tasa></rif:Rif>

    This XML string only has two lines

    How I can access a particular record, for example, rif:Nombre (this is the legal name of the client) or any records started like (rif:)?

    Thanking your support and attention

    Sorry for my bad english, I translate this with google translator :)

    Hi and welcome to devnet,

    You can use Qt's XML/ XML patterns modules to parse your data.

    Be aware that you have a problem with your code here. Each time you call on_queryButton_clicked you create a new QNAM which is not needed. Just create it once as a member variable and re-use it to make your queries.
