If I understood you correctly

<xsl:template match="/">
  <xsl:for-each select="rootelem/TAG/E">
    <xsl:variable name="A" select="preceding::A[1]" />
    <xsl:choose>
      <xsl:when test="$A = 'value1'">Label1</xsl:when>
      <xsl:when test="$A = 'value2'">Label2</xsl:when>
      <xsl:otherwise>Label3</xsl:otherwise>
    </xsl:choose>
    <xsl:text> </xsl:text><xsl:value-of select="." /><xsl:text>&#xA;</xsl:text>
  </xsl:for-each>
</xsl:template>

displays how it can be achieved. It may be worth testing if keys could speed things up, but if your document is smallish, preceding axis may be faster.
