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:mode name="split" on-no-match="shallow-copy"/>

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>
