和规则如果属性中的日期＆＃39; atr_ext_var_list_max_until＆＃39; ＆lt; =当前 日期比：
‘atr_storage_num’ must be empty ‘atr_shelf_num’ must be empty ‘atr_renewable_goods_quantity’ set to 0

在变量$ con我得到09142017和12319999，但我需要yyyyMMdd。带索引的子串没有帮助，与$ mmm1，$ dd，$ yyyy的组合也没有帮助。我检查了字符串长度（$ con），值非常奇怪：09142017为096,12319999为126。
我的XSL有什么不对？如何获得以下日期格式 - yyyyMMdd？ 谢谢你的回答！
答案 0 :(得分：1)
为了获得所需的日期格式，需要修改一些事情
将从<xsl:choose>收到的值分配给变量mon。目前<xsl:choose>未分配值。
<xsl:variable name="mon">
<xsl:choose>
<xsl:when test="$mmm = 'JAN' or $mmm='jan'">01</xsl:when>
<xsl:when test="$mmm = 'FEB' or $mmm='feb'">02</xsl:when>
<xsl:when test="$mmm = 'MAR' or $mmm='mar'">03</xsl:when>
<xsl:when test="$mmm = 'APR' or $mmm='apr'">04</xsl:when>
<xsl:when test="$mmm = 'MAY' or $mmm='may'">05</xsl:when>
<xsl:when test="$mmm = 'JUN' or $mmm='jun'">06</xsl:when>
<xsl:when test="$mmm = 'JUL' or $mmm='jul'">07</xsl:when>
<xsl:when test="$mmm = 'AUG' or $mmm='aug'">08</xsl:when>
<xsl:when test="$mmm = 'SEP' or $mmm='sep'">09</xsl:when>
<xsl:when test="$mmm = 'OCT' or $mmm='oct'">10</xsl:when>
<xsl:when test="$mmm = 'NOV' or $mmm='nov'">11</xsl:when>
<xsl:when test="$mmm = 'DEC' or $mmm='dec'">12</xsl:when>
</xsl:choose>
</xsl:variable>
更新以下声明
<xsl:variable name="con" select="concat($dd, $yyyy)"/>
到
<xsl:variable name="con" select="concat($yyyy,$mon,$dd)" />
这应该在YYYYMMDD中提供日期格式。
<con>20170914</con>
请优化XSLT，因为模板中有许多冗余代码和逻辑。
