You need to restructure your stylesheet alike this
  <xsl:template match="/">
    <xsl:result-document href="file1.xml">
      <xsl:for-each select="groups/group/title[matches(., '^file 1', 
'i')]">
        <contentOfTitleElmt>
          <xsl:value-of select="."/>
        </contentOfTitleElmt>
      </xsl:for-each>
    </xsl:result-document>
    <xsl:result-document href="file2.xml">
      <xsl:for-each select="groups/group/title[matches(., '^file 2', 
'i')]">
        <contentOfTitleElmt>
          <xsl:value-of select="."/>
        </contentOfTitleElmt>
      </xsl:for-each>
    </xsl:result-document>
    <xsl:result-document href="file3.xml">
      <xsl:for-each select="groups/group/title[not(matches(., '^file 
1', 'i') and matches(., '^file 2', 'i'))]">
        <contentOfTitleElmt>
          <xsl:value-of select="."/>
        </contentOfTitleElmt>
      </xsl:for-each>
    </xsl:result-document>
  </xsl:template>
