I have a wikipedia dump that I want to parse, and I am having some difficulties/mysterious problems while using Python xml parser, ElementTree.

My recent problem is, ElementTree does not seem to find the texts that are actually there. This is an example data:

<page>
 <title>Cengiz Han</title>
 <ns>0</ns>
 <id>10</id>
 <revision>
 <id>20337884</id>
 <parentid>20218916</parentid>
 <timestamp>2019-01-29T14:02:43Z</timestamp>

 <comment>China_11b.jpg dosyası Map_of_China_1142.jpg ile değiştirildi</comment>
 <model>wikitext</model>
 <format>text/x-wiki</format>
 <text xml:space="preserve">
 ...some long Genghis Khan stuff...
 </text>
</page>

Now when I parse it with this:

for event, elem in et.iterparse('dataset/wiki_test', events=('start', 'end', 'start-ns', 'end-ns')):
 if event == 'start':
 if elem.tag == 'page':
 if len(list(elem)) == 0:
 continue
 title = elem.find('title').text
 if title == None or 'MediaWiki' in title:
 elem.clear()
 continue
 wiki_id = elem.find('id')
 if wiki_id == None:
 elem.clear()
 continue
 wiki_id = wiki_id.text
 revision = elem.find('revision')
 if revision != None:
 print(list(revision))
 text = revision.find('text').text
 print(text)
 if text != None:
 count += 1
 titles += title + 'n'
 page = 'wiki_id': wiki_id, 'title': title, 'text': text.text
 pages += json.dumps(page, ensure_ascii=False) + 'n'
 elem.clear()

revision.find('text').text line seems to find no text for some elements, including the one above, and that some makes like one seventh of my data, which is annoying. This was also the case for page->id for some other entries, in which it claimed that element does not exist at all. I solved that problem by ignoring that ones, but I don't really want to do that, also this error does not make sense to me at all.

Here is another page, which works totally fine.

<page>
 <title>Mustafa Suphi</title>
 <ns>0</ns>
 <id>22</id>
 <revision>
 <id>20077185</id>
 <parentid>20017115</parentid>

What am I doing wrong?

You have posted two examples: "working" and "not working".

In the "not working" one there is no

</revision>

Are you sure this the XML you have or it is just copy & paste mistake.
