        QWebPage.__init__(self)
        # Specifies whether images are automatically loaded in web pages.
        self.settings().setAttribute(QWebSettings.AutoLoadImages, False)

class Name_Creater(QWebView):
    def __init__(self):
        QWebView.__init__(self)
        self.setPage(MyBrowser())
        self.loadFinished.connect(self.grab_first_name)
        self.frame = self.page().mainFrame()

    def grab_first_name(self):
        html = unicode(self.frame.toHtml()).encode('utf-8')
        soup = bs(html)
        for name in soup.findAll('li', text=True):
            print name

if __name__ == '__main__':
    app = QApplication(sys.argv)
    url_first_names = QUrl("http://www.genealogyroadtrip.com/Census/male_names_1.htm")
    br = Name_Creater()
    br.load(url_first_names)
    br.show()
    app.exec_()

Answer 1

The problem is that you are connecting to the loadFinished signal of the QWebView, which will be emitted once for each page that is loaded. So if there are multiple frames, there will be multiple loadFinished signals emitted.

The solution is to connect to the loadFinished signal of the mainFrame:

self.setPage(MyBrowser())
self.frame = self.page().mainFrame()
self.frame.loadFinished.connect(self.grab_first_name)
