Example 2:c++
Example 3:c++ // Assume there is a QDomElement named "price" in the XML document QString tagName = price.tagName(); // tagName will be "price" ``` In all of these examples, the QDomElement.tagName() method is used to retrieve the tag name of an XML element. The tag name is then stored in a QString variable for later use. The QDomElement.tagName property is part of the Qt Core module, specifically the Qt XML module.
