WebElement (gb.qt4.webkit)

That class provides convenient access to DOM elements in a WebFrame.

A WebElement object allows easy access to the document model, represented by a tree-like structure of DOM elements. The root of the tree is called the document element and can be accessed using WebFrame.Document.

Specific elements can be accessed using FindAll and FindFirst. These elements are identified using CSS selectors.

Alternatively you can traverse the document manually using the First, Next, Parent... properties.
