The first item in the list may be a string. If no_leading_text is true, then it will be an error if there is leading text, and it will always be a list of only elements.

If 'create_parent' is true (or is a tag name) then a parent node will be created to encapsulate the HTML in a single element. In this case, leading or trailing text is allowed.

This tries to minimally parse the chunk of text, without knowing if it is a fragment or a document. 'base_url' will set the document's base_url attribute (and the tree's docinfo.URL) If `guess_charset` is true, or if the input is not Unicode but a byte string, the `chardet` library will perform charset guessing on the string. zstring required)r% r$ N�2 �ascii�replacez<htmlz <!doctype�head�bodyr- ���r r( �span)r r r r' r! �decode�lstrip�lower� startswithr r1 r/ r) r2 r r )r# r$ r% �doc�startr: r; r r r � fromstring� s* rD c C sz |dkr t }t| t�s(| }|dkr\d}n4t| �rFt| �}|dkr\d}nt| d�}|dkr\d}i }|rl||d< |j|f|�S )a* Parse a filename, URL, or file-like object into an HTML document tree. Note: this returns a tree, not an element. Use ``parse(...).getroot()`` to get the document root. If ``guess_charset`` is true, the ``useChardet`` option is passed into html5lib to enable character detection. This option is on by default when parsing from URLs, off by default when parsing from file(-like) objects (which tend to return Unicode more often than not), and on by default when parsing from a file path (which is read in binary mode).
