+lxml-based doctest output comparison.
+
+Note: normally, you should just import the `lxml.usedoctest` and
+`lxml.html.usedoctest` modules from within a doctest, instead of this
+one::
+
+    >>> import lxml.usedoctest # for XML output
+
+    >>> import lxml.html.usedoctest # for HTML output
+
+To use this module directly, you must call ``lxmldoctest.install()``,
+which will cause doctest to use this in all subsequent calls.
+
+This changes the way output is checked and comparisons are made for
+XML or HTML-like content.
+
+XML or HTML content is noticed because the example starts with ``<``
+(it's HTML if it starts with ``<html``).  You can also use the
+``PARSE_HTML`` and ``PARSE_XML`` flags to force parsing.
+
+Some rough wildcard-like things are allowed.  Whitespace is generally
+ignored (except in attributes).  In text (attributes and text in the
+body) you can use ``...`` as a wildcard.  In an example it also
+matches any trailing tags in the element, though it does not match
+leading tags.  You may create a tag ``<any>`` or include an ``any``
+attribute in the tag.  An ``any`` tag matches any tag, while the
+attribute matches any and all attributes.
+
+When a match fails, the reformatted example and gotten text is
+displayed (indented), and a rough diff-like output is given.  Anything
+marked with ``+`` is in the output but wasn't supposed to be, and
+similarly ``-`` means its in the example but wasn't in the output.
+
+You can disable parsing on one line with ``# doctest:+NOPARSE_MARKUP``

+
+    Incremental parser.
+
+    Parses XML into a tree and generates tuples (event, element) in a
+    SAX-like fashion. ``event`` is any of 'start', 'end', 'start-ns',
+    'end-ns'.
+
+    For 'start' and 'end', ``element`` is the Element that the parser just
+    found opening or closing.  For 'start-ns', it is a tuple (prefix, URI) of
+    a new namespace declaration.  For 'end-ns', it is simply None.  Note that
+    all start and end events are guaranteed to be properly nested.
+
+    The keyword argument ``events`` specifies a sequence of event type names
+    that should be generated.  By default, only 'end' events will be
+    generated.
+
+    The additional ``tag`` argument restricts the 'start' and 'end' events to
+    those elements that match the given tag.  The ``tag`` argument can also be
+    a sequence of tags to allow matching more than one tag.  By default,
+    events are generated for all elements.  Note that the 'start-ns' and
+    'end-ns' events are not impacted by this restriction.
+
+    The other keyword arguments in the constructor are mainly based on the
+    libxml2 parser configuration.  A DTD will also be loaded if validation or
+    attribute default values are requested.
+
+    Available boolean keyword arguments:
+     - attribute_defaults: read default attributes from DTD
+     - dtd_validation: validate (if DTD is available)
+     - load_dtd: use DTD for parsing
+     - no_network: prevent network access for related files
+     - remove_blank_text: discard blank text nodes
+     - remove_comments: discard comments
+     - remove_pis: discard processing instructions
+     - strip_cdata: replace CDATA sections by normal text content (default: 
+       True for XML, ignored otherwise)
+     - compact: safe memory for short text content (default: True)
+     - resolve_entities: replace entities by their text value (default: True)
+     - huge_tree: disable security restrictions and support very deep trees
+                  and very long text content (only affects libxml2 2.7+)
+     - html: parse input as HTML (default: XML)
+     - recover: try hard to parse through broken input (default: True for HTML,
+                False otherwise)
+
+    Other keyword arguments:
+     - encoding: override the document encoding
+     - schema: an XMLSchema to validate against

+
+    The XML parser.
+
+    Parsers can be supplied as additional argument to various parse
+    functions of the lxml API.  A default parser is always available
+    and can be replaced by a call to the global function
+    'set_default_parser'.  New parsers can be created at any time
+    without a major run-time overhead.
+
+    The keyword arguments in the constructor are mainly based on the
+    libxml2 parser configuration.  A DTD will also be loaded if DTD
+    validation or attribute default values are requested (unless you
+    additionally provide an XMLSchema from which the default
+    attributes can be read).
+
+    Available boolean keyword arguments:
+
+    - attribute_defaults - inject default attributes from DTD or XMLSchema
+    - dtd_validation     - validate against a DTD referenced by the document
+    - load_dtd           - use DTD for parsing
+    - no_network         - prevent network access for related files (default: True)
+    - ns_clean           - clean up redundant namespace declarations
+    - recover            - try hard to parse through broken XML
+    - remove_blank_text  - discard blank text nodes that appear ignorable
+    - remove_comments    - discard comments
+    - remove_pis         - discard processing instructions
+    - strip_cdata        - replace CDATA sections by normal text content (default: True)
+    - compact            - save memory for short text content (default: True)
+    - collect_ids        - use a hash table of XML IDs for fast access (default: True, always True with DTD validation)
+    - huge_tree          - disable security restrictions and support very deep trees
+                           and very long text content (only affects libxml2 2.7+)
+
+    Other keyword arguments:
+
+    - resolve_entities - replace entities by their text value: False for keeping the
+          entity references, True for resolving them, and 'internal' for resolving
+          internal definitions only (no external file/URL access).
+          The default used to be True and was changed to 'internal' in lxml 5.0.
+    - encoding - override the document encoding (note: libiconv encoding name)
+    - target   - a parser target object that will receive the parse events
+    - schema   - an XMLSchema to validate against
+
+    Note that you should avoid sharing parsers between threads.  While this is
+    not harmful, it is more efficient to use separate parsers.  This does not
+    apply to the default parser.

+
+    The HTML parser.
+
+    This parser allows reading HTML into a normal XML tree.  By
+    default, it can read broken (non well-formed) HTML, depending on
+    the capabilities of libxml2.  Use the 'recover' option to switch
+    this off.
+
+    Available boolean keyword arguments:
+
+    - recover            - try hard to parse through broken HTML (default: True)
+    - no_network         - prevent network access for related files (default: True)
+    - remove_blank_text  - discard empty text nodes that are ignorable (i.e. not actual text content)
+    - remove_comments    - discard comments
+    - remove_pis         - discard processing instructions
+    - compact            - save memory for short text content (default: True)
+    - default_doctype    - add a default doctype even if it is not found in the HTML (default: True)
+    - collect_ids        - use a hash table of XML IDs for fast access (default: True)
+    - huge_tree          - disable security restrictions and support very deep trees
+                           and very long text content (only affects libxml2 2.7+)
+
+    Other keyword arguments:
+
+    - encoding - override the document encoding (note: libiconv encoding name)
+    - target   - a parser target object that will receive the parse events
+    - schema   - an XMLSchema to validate against
+
+    Note that you should avoid sharing parsers between threads for performance
+    reasons.
