Как использовать Python XML findall для поиска '‹v: imagedata r: id = rId7 o: title = 1-REN /›'

ET.findall() vs BS4.find_all():

• ElementTree's findall() is not recursive by default^*. It's only going to find direct children of the node provided. So in your case, it's only searching for image nodes directly under the root element.
  • ^* as per mzjn's comment below, prefixing the match argument (tag or path) with ".//" will search for that node anywhere in the tree, since it's supports XPath's.
• find_all() BeautifulSoup ищет всех потомков . Таким образом, он ищет узлы «imagedata» в любом месте дерева.

• Однако _7 _ выполняет поиск всех потомков. Использование примера "работа с пространствами имен" в документации:

  >>> for char in root.iter('{http://characters.example.com}character'):
  ...     print(' |-->', char.text)
  ...
   |--> Lancelot
   |--> Archie Leach
   |--> Sir Robin
   |--> Gunther
   |--> Commander Clement
  

• Sadly, ET.iterfind() which works with namespaces as a dict (like ET.findall), also does not search descendants, only direct children by default^*. Just like ET.findall. Apart from how empty strings '' in the tags are treated wrt the namespace, and one returns a list while the other returns an iterator, I can't say there's a meaningful difference between ET.findall and ET.iterfind.
  • ^* As above for ET.findall(), prefixing ".//" makes it search the entire tree (matches with any node).

namespace = {'v': "urn:schemas-microsoft-com:vml"}
results = ET.fromstring(xml).findall("v:imagedata", namespace)  # note the 'v:'

namespace = {'image': "urn:schemas-microsoft-com:vml"}
results = ET.fromstring(xml).findall("image:imagedata", namespace)

results = ET.fromstring(xml).findall(".//v:imagedata", namespace)
