from xml.dom import minidom

document = """\

<point>This is a demo</point>

"""
dom = minidom.parseString(document)
slideshows = dom.getElementsByTagName("point")
for slideshow in slideshows:
# print slideshow.getElementsByTagName('point')[0].firstChild.data
print slideshow.

If you look at the quick documentation lookup, you can see where it breaks. Code analysis seems to figure out signatures for the first call:

dom = minidom.parseString(document)
#Inferred type: (string: unknown, parser: unknown) -> Document

After that things seem to be less clear. There is no inferred type information available for the call to getElementsByTagName(). Also Go to Declaration offers to possible methods to go to (one in class Element and one in class Document). I guess that's the reason why completion stops working. It's interesting that Element shows up here as well, because there is no inheritance relationship. It only shares the base class with Document.

Given how complicated parseString() is (calls multiple levels deep, conditional imports), I'm amazed that there is code completion for this at all...

Hi yanglei_fage,

code analysis in complicated for lxml module and we're trying to do our best.
As a workaround you can specify type for the slideshows (please see webhelp)
