As Tilman pointed out XFA is XML so as soon as you have the XML you can extract the content you are interested in.
If you have a static XFA based form (i.e. there is an XFA entry and the /Fields entry is not empty) you can safely ignore the fact that it's XFA and do the text extraction as you'd do for a 'normal' PDF. For a dynamic XFA based PDF you could parse the XML but please note that do to it's dynamic nature the correct state of the rendered document is determined at runtime executing data binding rules and JavaScript so can not be dertermined without rendering the XFA first. You could statically extract the content you are interested in from the XML though. AFAIK Apache Tika does some (static) extraction of XFA content (fields).
