how can delete auto element of id "1" using qt library?

it's pretty straightforward:

qdomdocument doc; qfile file("/tmp/1.xml"); file.open(qfile::readonly); doc.setcontent(&file); qdomelement plan = doc.documentelement(); qdomnodelist cars = plan.childnodes(); for(int = 0; < cars.count(); i++) { qdomnode node = cars.at(i); if (node.iselement() && node.toelement().attribute("id") == "1") { plan.removechild(node); } } qdebug() << doc.tostring();
