{{ entry.body | retconAttr( 'p', { 'class' : 'someClass' } ) }}

Add a class for all p tags (will not remove any existing classes)

{{ entry.body | retconAttr( 'p', { 'class' : 'someClass' }, false ) }}

Add a class to several selectors at once

{{ entry.body | retconAttr( [ '.foo', '.bar' ], { 'class' : 'someClass' } ) }}

Remove inline styles for all elements

{{ entry.body | retconAttr( '*', { 'style' : false } ) }}

Add multiple attributes

{{ entry.body | retconAttr( '.foo', { 'class' : 'bar', 'data-baz' : 'qux' } ) }}

Add an attribute without a value
