Here is an attempt with XSLT 2.0:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  version="2.0">

  <xsl:output method="xml" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:variable name="pn" select="//*[@i = '9']"/>

  <xsl:template match="/">
    <ROOT>
      <BEFORE>
        <xsl:apply-templates select="*" mode="before"/>
      </BEFORE>
      <PULLED_OUT>
        <xsl:copy-of select="$pn"/>
      </PULLED_OUT>
      <AFTER>
        <xsl:apply-templates select="*" mode="after"/>
      </AFTER>
    </ROOT>
  </xsl:template>

  <xsl:template match="*[. &gt;&gt; $pn or . is $pn]" mode="before"/>

  <xsl:template match="*[. is $pn or empty(. intersect $pn/ancestor::*) 
and empty(. intersect $pn/following-sibling::*)]" mode="after"/>

  <xsl:template match="*" mode="before">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()" mode="before"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*" mode="after">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()" mode="after"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="@* | text() | comment() | 
processing-instruction()" mode="after before">
    <xsl:copy/>
  </xsl:template>

</xsl:stylesheet>
