You can use this XSLT template:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" encoding="utf-8" />

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

<xsl:template match="/SHOP/SHOPITEM">
  <xsl:element name="SHOPITEM">
    <title><xsl:value-of select="title" /></title>
    <unit><xsl:value-of select="unit" /></unit>
    <text>
      <xsl:call-template name="join">
        <xsl:with-param name="list" select="text" />
      </xsl:call-template>
    </text>
  </xsl:element>
</xsl:template>

<xsl:template name="join">
  <xsl:param name="list" />
  <xsl:for-each select="$list">
    <xsl:value-of select="." />
    <xsl:if test="position() != last()">
      <br />
    </xsl:if>
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Usage:

$xsl_doc = new DOMDocument;
$xsl_doc->loadXML($xsl);

$xml_doc = new DOMDocument;
$xml_doc->loadXML($xml);

$xslt = new XSLTProcessor();
$xslt->importStyleSheet($xsl_doc);

$new_xml_doc = $xslt->transformToDoc($xml_doc);

echo $new_xml_doc->saveXML();
