The usual way in XSLT 3, if you know the content of a row is x and y or
even a simple sequence of text only children is composite grouping and
taking the first item in each group e.g.


<xsl:template match="Document">

B  <xsl:copy>

B B B  <xsl:for-each-group select="row" composite="yes" group-by="*">

B B B B B B  <xsl:sequence select="."/>

B B  </xsl:for-each-group>

</xsl:template>
