[PyQt] is there any Class in Qt for pulling data out of HTML?

[iMath]

the Qt documentation says

The Qt XML Module is provided for compatibility with older code. It has been superseded by the QXMLStreamReader and QXMLStreamWriter classes in the Qt Core Module.

I think we can use QDom* class to get data out of HTML before this claim ,although I never used it. does this claim mean we can use QXmlStreamReader for pulling data out of HTML ? I don't know the difference between XML and HTML.‍
