@Martin, your example works really well. I had to edit the expression,
as in my real files sometimes they have used lists instead of
linebreaks:

<xsl:param name="lb"
as="xs:string">&lt;/?(li|ul|br)\s*/?&gt;</xsl:param>

However, I can see what I would also need to split at the end of
sentences when there's no escaped tag but just final punctuation. To
avoid the transformation eating the punctuation, I have tried with a
lookbehind assertion but it seems it's not supported:

<xsl:param name="lb"
as="xs:string">(?<=[.!?])\s|&lt;/?(li|ul|br)\s*/?&gt;</xsl:param>

Any ideas?

In general, if there is markup, it might be better to try to parse it,
in your initial sample you seemed to have simple HTML empty element
syntax with <br> elements, now with the adapted regular expression it
seems you expect opening and closing tags.

If you know the escaped markup is an XML fragment then I would try to
parse it with the "parse-xml-fragment" function, if it is HTML, then I
would look into using David Carlisle's HTML parser implementation done
in pure XSLT 2 or use an extension function like the commercial editions
of Saxon offer.

For HTML parsing with the XSLT based HTML parser
(https://github.com/davidcarlisle/web-xslt/blob/master/htmlparse/htmlparse.xs
l)
it would look like

B  <xsl:import
href="https://github.com/davidcarlisle/web-xslt/raw/master/htmlparse/htmlpars
e.xsl"/>

B  <xsl:template match="tu">
B B B B B  <xsl:variable name="split">
B B B B B B B B B  <xsl:apply-templates mode="split"/>
B B B B B  </xsl:variable>
B B B B B  <xsl:for-each-group select="$split/tuv/seg" group-by="position()
mod count($split/tuv[1]/seg)">
B B B B B B B B B  <tu tuid="{position()}">
B B B B B B B B B B B B B  <xsl:apply-templates
select="current-group()/snapshot()/.."/>
B B B B B B B B B  </tu>
B B B B B  </xsl:for-each-group>
B  </xsl:template>

B  <xsl:template match="seg" expand-text="yes" mode="split">
B B B B B  <xsl:for-each-group select="d:htmlparse(., '', true())/node()"
group-ending-with="br">
B B B B B B B B B  <xsl:if test=". instance of text()">
B B B B B B B B B B B  <seg>{.}</seg>
B B B B B B B B B  </xsl:if>
B B B B B  </xsl:for-each-group>
B  </xsl:template>
