How can I code a (REGEX?-) filter that only displays a part of the tiddler?

[JanJo]

@JanJo

<$let splitteR="<<pic" numbeR="2" currentTiddler="Charles Baudelaire">
<$list filter="[<currentTiddler>get[text]] +[splitregexp<splitteR>first<numbeR>join<splitteR>]" >
<div style="display:block">{{!!title}}</div>
</$list>
</$let>

If I examine this more closely I suspect that the filter removes the new lines \n…
How do I avoid this?

Solution to this problem here: How can I build a filter that uses split and join... and does not eat the \n newline characters?
