XSLT根据Key值XSLT1.0对xml元素进行分组

Question

我将在BizTalk

中收到如下的CRM Response XML

我必须根据ccx_immunizationid值计算不同的实体数量＆amp;如果两个实体具有相同的免疫ID，我也必须对这些字段进行分组。如果xml文件（没有名称空间）和字段是<ccx_immunizationid>2323</ccx_imunizationid>，我可以使用类似下面的内容，

<xsl:template match="//Entity/Attributes[not(./ccx_immunizationid= preceding::ccx_immunizationid)]">

但是在这里，我必须查找键'ccx_immunizationid'及其值。

我在BizTalk地图中使用自定义xslt。
