1）有多个<ORDER_TBL_TYPE_ITEM>。
2）内部<ORDER_TBL_TYPE_ITEM>多个<ORDER_LINES_TBL_TYPE_ITEM>存在。
3）对于每次迭代，我们需要一个分配给下面显示元素的数字序列，如果previous = current忽略level1,2,3元素并且直接传递ITEM值，则条件也存在。

您正在寻找的条件逻辑如下所示。我假设上下文节点是<colorItems>元素。
<xsl:if test="color != preceding-sibling::colorItems[1]/color">
... process Level1, 2, 3 ...
</xsl:if>
<xsl:copy-of select="color" />
