+    disable_entities=True,
+    process_comments=False,
+    **kwargs
+):
+    """Parse the given XML input and convert it into a dictionary.
+
+    `xml_input` can either be a `string`, a file-like object, or a generator of strings.
+
+    If `xml_attribs` is `True`, element attributes are put in the dictionary
+    among regular child elements, using `@` as a prefix to avoid collisions. If
+    set to `False`, they are just ignored.
+
+    Simple example::
+
+        >>> import xmltodict
+        >>> doc = xmltodict.parse(\"\"\"
+        ... <a prop="x">
+        ...   <b>1</b>
+        ...   <b>2</b>
+        ... </a>
+        ... \"\"\")
+        >>> doc['a']['@prop']
+        u'x'
+        >>> doc['a']['b']
+        [u'1', u'2']
+
+    If `item_depth` is `0`, the function returns a dictionary for the root
+    element (default behavior). Otherwise, it calls `item_callback` every time
+    an item at the specified depth is found and returns `None` in the end
+    (streaming mode).
+
+    The callback function receives two parameters: the `path` from the document
+    root to the item (name-attribs pairs), and the `item` (dict). If the
+    callback's return value is false-ish, parsing will be stopped with the
+    :class:`ParsingInterrupted` exception.
+
+    Streaming example::
+
+        >>> def handle(path, item):
+        ...     print('path:%s item:%s' % (path, item))
+        ...     return True
+        ...
+        >>> xmltodict.parse(\"\"\"
+        ... <a prop="x">
+        ...   <b>1</b>
+        ...   <b>2</b>
+        ... </a>\"\"\", item_depth=2, item_callback=handle)
+        path:[(u'a', {u'prop': u'x'}), (u'b', None)] item:1
+        path:[(u'a', {u'prop': u'x'}), (u'b', None)] item:2
+
+    The optional argument `postprocessor` is a function that takes `path`,
+    `key` and `value` as positional arguments and returns a new `(key, value)`
+    pair where both `key` and `value` may have changed. Usage example::
+
+        >>> def postprocessor(path, key, value):
+        ...     try:
+        ...         return key + ':int', int(value)
+        ...     except (ValueError, TypeError):
+        ...         return key, value
+        >>> xmltodict.parse('<a><b>1</b><b>2</b><b>x</b></a>',
+        ...                 postprocessor=postprocessor)
+        ObjectDict([(u'a', ObjectDict([(u'b:int', [1, 2]), (u'b', u'x')]))])
+
+    You can pass an alternate version of `expat` (such as `defusedexpat`) by
+    using the `expat` parameter. E.g:
+
+        >>> import defusedexpat
+        >>> xmltodict.parse('<a>hello</a>', expat=defusedexpat.pyexpat)
+        ObjectDict([(u'a', u'hello')])
+
+    You can use the force_list argument to force lists to be created even
+    when there is only a single child of a given level of hierarchy. The
+    force_list argument is a tuple of keys. If the key for a given level
+    of hierarchy is in the force_list argument, that level of hierarchy
+    will have a list as a child (even if there is only one sub-element).
+    The index_keys operation takes precedence over this. This is applied
+    after any user-supplied postprocessor has already run.
+
+        For example, given this input:
+        <servers>
+          <server>
+            <name>host1</name>
+            <os>Linux</os>
+            <interfaces>
+              <interface>
+                <name>em0</name>
+                <ip_address>10.0.0.1</ip_address>
+              </interface>
+            </interfaces>
+          </server>
+        </servers>
+
+        If called with force_list=('interface',), it will produce
+        this dictionary:
+        {'servers':
+          {'server':
+            {'name': 'host1',
+             'os': 'Linux'},
+             'interfaces':
+              {'interface':
+                [ {'name': 'em0', 'ip_address': '10.0.0.1' } ] } } }
+
+        `force_list` can also be a callable that receives `path`, `key` and
+        `value`. This is helpful in cases where the logic that decides whether
+        a list should be forced is more complex.
+
+
+        If `process_comment` is `True` then comment will be added with comment_key
+        (default=`'#comment'`) to then tag which contains comment
+
+            For example, given this input:
+            <a>
+              <b>
+                <!-- b comment -->
+                <c>
+                    <!-- c comment -->
+                    1
+                </c>
+                <d>2</d>
+              </b>
+            </a>
+
+            If called with process_comment=True, it will produce
+            this dictionary:
+            'a': {
+                'b': {
+                    '#comment': 'b comment',
+                    'c': {
+
+                        '#comment': 'c comment',
+                        '#text': '1',
+                    },
+                    'd': '2',
