attr_formatter.py
|
|
|
|
This module contains a function `format` that modifies a BeautifulSoup object in place.
|
|
The function searches for all elements with the attribute "dj-attr".
|
|
The value of "dj-attr" is expected to be a string with pairs of attributes and values separated by semicolons (;),
|
|
and each pair separated by tildes (~). For each found element, it splits the "dj-attr" value into attribute-value pairs,
|
|
formats the value into a Django template variable format (i.e., "{{ value }}"), and assigns it to the corresponding
|
|
attribute of the element. After processing all attribute-value pairs, it removes the "dj-attr" attribute from
|
|
the element.
|
|
|
|
Example:
|
|
If an element is <div dj-attr="class;my-class~id;my-id"></div>,
|
|
after processing, it becomes <div class="{{ my-class }}" id="{{ my-id }}"></div>.
