[−][src]Function marked::filter::text_normalize
pub fn text_normalize(pos: NodeRef, data: &mut NodeData) -> Action
Normalize text nodes by merging, replacing control characters and minimizing whitespace.
The filter is aware of whitespace significance rules in HTML <pre>
(or
similar tag) blocks as well as block vs inline elements in general. It
assumes, without knowledge of any potential unconventional external styling,
that leading and trailing whitespace may be removed at block element
boundaries.
Because this filter works on text nodes, results are better if applied in
its own Document::filter
pass, depth first, and after any pass
containing filters that detach or fold elements, such as
detach_banned_elements
or fold_empty_inline
. Otherwise the filter
may not be able to merge text node's which become siblings too late in the
process, resulting in additional unnecessary whitespace.
