global name 'extract' is not defined

[cifkao]

The multithreaded version doesn't work with the --article option. WikiExtractor.py:1831 causes NameError: global name 'extract' is not defined.

Does the single-threaded version work with the --article option? If so, how do you invoke it?

python WikiExtractor.py -a /Wikipedia/Train.xml --threads 1

Returns the same extract undefined error

I have a fix for this problem, but I cannot commit at this time, since there are a number of other fixes coming.
The change for this is to replace the call to extract() with:
Extractor(id, title, [page]).extract()
and then change the method extract to this:
def extract(self, out=sys.stdout):
text = ''.join(self.page)
url = get_url(self.id)
header = '\n' % (self.id, url, self.title)
# Separate header from text with a newline.
header += self.title + '\n\n'
header = header.encode('utf-8')
text = clean(text)
footer = "\n\n"
if out != sys.stdout:
out.reserve(len(header) + len(text) + len(footer))
out.write(header)
for line in compact(text):
out.write(line.encode('utf-8'))
out.write('\n')
out.write(footer)

Fixed in latest commit.
