I would be tempted to tackle it with for-each-group group-starting-with


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

 B  <xsl:template match="root">
 B  B  <xsl:copy>
 B  B  B  <xsl:for-each-group select="*"
group-starting-with="p[following-sibling::*[1][self::x]]">
 B  B  B  B  <xsl:choose>
 B  B  B  B  B  <xsl:when test="self::p[following-sibling::*[1][self::x]]">
 B  B  B  B  B  B  <xsl:copy>
 B  B  B  B  B  B  B  <xsl:apply-templates select="current-group()[2],
node()"/>
 B  B  B  B  B  B  </xsl:copy>
 B  B  B  B  B  B  <xsl:apply-templates select="current-group()[position() gt
2]"/>
 B  B  B  B  B  </xsl:when>
 B  B  B  B  B  <xsl:otherwise>
