strip_linefeeds
This modifier removes any linefeed characters (“returns”) from the input.
Example
The following example removes all HTML from the Entry Body then strips all linefeeds — effectively turning many paragraphs into a single big chunk of text.
<mt:EntryBody remove_html="1" strip_linefeeds="1">
