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`` � )�etreeN)�escape)� PARSE_HTML� PARSE_XML�NOPARSE_MARKUP�LXMLOutputChecker�LHTMLOutputChecker�install� temp_installr r r c C s | d u r d S | � � S d S �N)�strip��v� r �?/usr/local/lib64/python3.9/site-packages/lxml/doctestcompare.pyr 8 s r c C s t �d| �S )N� )�_norm_whitespace_re�subr r r r �norm_whitespace> s r FT)ZrecoverZremove_blank_textc C s t �| t�S r )r � fromstring� _html_parser��htmlr r r �html_fromstringC s r z^<[^>]+ (at|object) z[ \t\n][ \t\n]+c @ s� e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dd� Z d'dd�Z d(dd�Z d)dd�Zdd� Zd d � Zd d � Zd d!� Zd"d#� Zd*d$d%�Zd&S )+r ) �param�img�area�br�basefont�input�base�meta�link�colc C s t jS r )r �XML��selfr r r �get_default_parserP s z$LXMLOutputChecker.get_default_parserc C s� t | dd �}|d ur | j}|} ntj}| �|||�}|sF|| |||�S z ||�}W n tjyh Y dS 0 z ||�}W n tjy� Y dS 0 | �||�S )N�_temp_override_selfF)�getattr� _temp_call_super_check_output� OutputChecker� check_output� get_parserr �XMLSyntaxError� compare_docs) r& �want�got� optionflagsZalt_selfZ super_method�parser�want_doc�got_docr r r r, S s& � z LXMLOutputChecker.check_outputc C st d }t |@ rd S t|@ r t}nRt|@ r.tj}nB|�� �� �d�rT|�� �d�rTt}n | � |�rp| � |�rp| � � }|S )Nz<html) r r r r r r$ r �lower� startswith�_looks_like_markupr' )r& r0 r1 r2 r3 r r r r- h s � �z LXMLOutputChecker.get_parserc C s |� � }|�d�o t�|� S )N�<)r r7 �_repr_re�search)r& �sr r r r8 x s �z$LXMLOutputChecker._looks_like_markupc C s | � |j|j�sdS | �|j|jd�s*dS | �|j|jd�s@dS d|jvr�t|j�� �}t|j�� �}||krrdS |D ]$}| �|j| |j| d�sv dS qv|jdks�t|��rt |�}t |�}|s�|�r|r�|s�dS |� d�}|� d�} | � || �s�dS |s�|jdkr��qq�dS )NFT�anyz...r ) � tag_compare�tag� text_compare�text�tail�attrib�sorted�keys�len�list�popr/ ) r& r0 r1 Z want_keysZgot_keys�key� want_children� got_childrenZ want_firstZ got_firstr r r r/ } s6 z LXMLOutputChecker.compare_docsc C s^ |pd}|pd}|r,t |��� }t |��� }dt�|� }|�dd�}t�||�rVdS dS d S )N� z^%s$z\.\.\.z.*TF)r r �rer �replacer; )r& r0 r1 r r r r r@ � s z LXMLOutputChecker.text_comparec C sr |dkr dS t |ttf�r(t |ttf�s0||kS |p6d}|p>d}|�d�rf|�d�d |�d�d kS ||kS d S )Nr= TrL z{...}�}���)� isinstance�str�bytesr7 �split)r& r0 r1 r r r r> � s � z LXMLOutputChecker.tag_comparec C s |j }| �|||�}g }|d ur�z ||�}W n. tjyZ t�� d }|�d| � Y n0 z ||�} W n. tjy� t�� d }|�d| � Y n0 |d u s�|r�t�| |||�} |r�|�| � d� |�S | S |t u } d| � || d�d| � | | d�d| � || | d�g} d� | �S ) N� zIn example: %szIn actual output: %s� z Expected:� zGot:zDiff:) r0 r- r r. �sys�exc_info�appendr+ �output_difference�joinr � format_doc� collect_diff) r& Zexampler1 r2 r0 r3 �errorsr4 �er5 �valuer Z diff_partsr r r r[ � s> � �z#LXMLOutputChecker.output_differenceTc C s. |sdS |j | jvrdS |js&t|�r*dS dS )NFT)r?
