That part could be done with


<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
     xmlns:xs="http://www.w3.org/2001/XMLSchema";
     exclude-result-prefixes="#all"
     version="3.0">

   <xsl:mode on-no-match="shallow-copy"/>

   <xsl:mode name="insert-markers" on-no-match="shallow-copy"/>

   <xsl:template match="textlines">
       <xsl:copy>
           <xsl:variable name="transformed-textlines">
               <xsl:apply-templates mode="insert-markers"/>
           </xsl:variable>
           <xsl:for-each-group select="$transformed-textlines/node()"
group-ending-with="lb">
               <line>
                   <xsl:apply-templates select="current-group()"/>
               </line>
           </xsl:for-each-group>
       </xsl:copy>
   </xsl:template>

   <xsl:template mode="insert-markers" match="text()">
       <xsl:analyze-string select="." regex="\n+">
           <xsl:matching-substring>
               <lb/>
           </xsl:matching-substring>
           <xsl:non-matching-substring>
               <xsl:value-of select="."/>
           </xsl:non-matching-substring>
       </xsl:analyze-string>
   </xsl:template>

   <xsl:template match="lb"/>

</xsl:stylesheet>
