}示例3: clearNodes
// Clears nodes within the specified nodeMap
void clearNodes( DefSections &nodeMap )
{
DefSections::iterator myIter;
for( myIter = nodeMap.begin(); myIter != nodeMap.end(); ++myIter )
{
QDomElement node = myIter.data();

}
nodeMap.clear(); // Delete it's contents
}示例4: readChildElement
/**
* This method is used to read a child XML object of a XML object
* @param parent The parent XML object
* @param key The name of the child
* @return The child node
