Detailed Description

The QWebElementCollection class represents a collection of web elements.

Elements in a document can be selected using QWebElement::findAll() or using the QWebElement constructor. The collection is composed by choosing all elements in the document that match a specified CSS selector expression.

The number of selected elements is provided through the count() property. Individual elements can be retrieved by index using at().

It is also possible to iterate through all elements in the collection using Qt's foreach macro:

 QWebElementCollection collection = document.findAll("p");
 foreach (QWebElement paraElement, collection) {
     ...
 }
