这是我用来转换它的XSLT，用户@Parfait告诉我如何构建在一个非常相似的帖子上。如果OPTYPE是EU，那么输出将有另一个名为altPersonID的输出元素;然后idType将设置personInfo属性。
This is the XSLT I'm using to transform it, that user @Parfait teached me how to build on a very similar post. If OPTYPE is EU, then the output will have another output element called altPersonID; Then idType will set the personInfo attributes.

basically, if you see the XSLT FIDDLE below, you’ll see that it’s outputing always in the same way, whether is OPTYPE is EU or EI and IDTYPE is i1 or i2

It’s a bit hard to give a precise answer because you have not shown your expected output, but it looks like the problem is that you have declared the op_type and id_type variables before the xsl:for-each-group

<xsl:template match="table">
<xsl:variable name="op_type">

</xsl:variable>
<xsl:variable name="id_type">
<xsl:value-of select="table-band/row/cell[position()=10]/data"/>

count(ancestor::table/table-band[1]/row/cell[label='PERSONNAME']/preceding-sibling::*)+1]/data">
<xsl:choose>
....
What this means is that (as you are using XSLT 3.0), that op_type variable will contain the value of all \"optype\" cells concatenated into one string. You could see this if you did an xsl:value-of after your declaration

<xsl:value-of select="$op_type" />
This returns the following
This returns the following
EI EU EU EU EI
What you need to do move the declaration inside the xsl:for-each-group so that it is selects the value for the first row in the group.
