Здравствуйте.
Создаю XML через дом-элементы.
Проблема в следующем - при записи большого массива данных записываются не все, в только первая часть. Притом ограничение примерно 20 кб.
QDomElement Argoenergo::SetArea(QDomDocument& domDoc, int starttime, int stoptime, QList<int> points)
{
QDomElement domElement = domDoc.createElement("area");
QDomElement inn = domDoc.createElement("inn");
QDomElement name = domDoc.createElement("name");
QDomText inn_text = domDoc.createTextNode("1234567890");
QDomText name_text = domDoc.createTextNode("Mega-company");
domElement.appendChild(inn);
inn.appendChild(inn_text);
domElement.appendChild(name);
name.appendChild(name_text);
QSqlQueryModel *sql_model = new QSqlQueryModel();
QString q = QString("SELECT ...");
sql_model->setQuery(q, currentDatabase());
QSqlQuery query = sql_model->query();
for(int i = 0; i < points.length(); i++)
{
QDomElement measurepoint = domDoc.createElement("measurepoint");
QDomAttr domAttr1 = domDoc.createAttribute("code");
domAttr1.setValue(QString("CODE_1234567%1").arg(points[i]));
measurepoint.setAttributeNode(domAttr1);
QDomAttr domAttr2 = domDoc.createAttribute("name");
domAttr2.setValue(QString("KTP 1121-7-%1").arg(points[i]));
measurepoint.setAttributeNode(domAttr2);
domElement.appendChild(measurepoint);
QDomElement measurecannel1 = domDoc.createElement("measurecannel");
QDomAttr domAttr11 = domDoc.createAttribute("code");
domAttr11.setValue("02");
measurecannel1.setAttributeNode(domAttr11);
QDomAttr domAttr21 = domDoc.createAttribute("desc");
domAttr21.setValue(QString(tr("Active energy, out")));
measurecannel1.setAttributeNode(domAttr21);
measurepoint.appendChild(measurecannel1);
int l = 0;
int k_1 = 0;
int prev = 0;
for(int k = 0; k < sql_model->rowCount(); k++)
{
if(sql_model->record(k).value("num_point").toInt() == points[i])
{
if(l == 0)
{
prev = sql_model->record(k).value("pwr").toDouble();
k_1 = k;
}
else
{
QDomElement period = domDoc.createElement("period");
QDomAttr periodStart = domDoc.createAttribute("start");
periodStart.setValue(sql_model->record(k_1).value("datetime_r").toDateTime().toString("hhmm"));
QDomAttr periodStop = domDoc.createAttribute("end");
periodStop.setValue(sql_model->record(k).value("datetime_r").toDateTime().toString("hhmm"));
period.setAttributeNode(periodStart);
period.setAttributeNode(periodStop);
QDomElement value = domDoc.createElement("value");
QDomText value_text = domDoc.createTextNode(QString("%1").arg(sql_model->record(k).value("pwr").toDouble() - sql_model->record(k_1).value("pwr").toDouble()));
if(sql_model->record(k).value("Status").toInt() != 0)
{
QDomAttr status = domDoc.createAttribute("status");
status.setValue(sql_model->record(k).value("status").toString());
value.setAttributeNode(status);
}
value.appendChild(value_text);
period.appendChild(value);
measurecannel1.appendChild(period);
k_1 = k;
}
l++;
}
}
}
return domElement;
}
В итоге при большом колличестве данных получаем:

</area>
Если обратить внимание на последних 5 секций <measurepoint>, то видно, что данные просто перестали записываться.
Данные есть все. При дебаге заходит везде, где надо и выполняет инструкции на запись и в последних 5 секциях. В чем проблема?
