How to withdraw additional group property in xsl template on hostcms 6?

Question

PHP

Writing:

<xsl:value-of select="property_value[tag_name='group-header-h167']/value"/>

Does not work.
Whole code:

<xsl:choose>
      <xsl:when test="/shop/ТекущаяГруппа = 0">
        <h1>
          <xsl:value-of disable-output-escaping="yes" select="name"/>
        </h1>
      </xsl:when>
      <xsl:otherwise>
        <xsl:variable name="currentGroup" select=".//shop_group[@id=/shop/ТекущаяГруппа]" />
        <h1>
          <xsl:value-of select="property_value[tag_name='group-header-h167']/value"/>
        </h1>
      </xsl:otherwise>
    </xsl:choose>

Answer 2

Something like this, if the group ID is previously obtained

<xsl:value-of disable-output-escaping="yes" select=".//shop_group[@id=$group]/property_value[tag_name='group-header-h167']/value"/>
