从平面xml创建嵌套xml时遇到问题

我试图使用XSLT从平面xml创建嵌套xml，但是我发现它只创建一个嵌套，而忽略了源xml中的其余记录

我的XML输入如下所示：

<?xml version="1.0" encoding="ISO-8859-1" ?>

XSLT应该识别顶级记录，然后添加子记录。对于top记录，它应将其irn和EADUNTITLE分别复制为TopID和TopTitle。对于每个子级，它应该包括直接的ParentID和ParentTitle以及TopID和TopTitle。输出应该如下所示：

我拥有的XSLT是：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:key name="child" match="tuple" use="tuple[@name='AssParentObjectRef']/atom[@name='irn']" />

<xsl:template match="/table">
    <table name="ecatalogue">
        <collection>
            <xsl:apply-templates select="tuple[not(tuple[@name='AssParentObjectRef']/atom[@name='irn'])]"/>
        </collection>
    </table>
</xsl:template>

<xsl:template match="tuple">
    <tuple>
        <xsl:copy-of select="atom"/>
        <xsl:if test="key('child', atom[@name='irn'])">
            <tuple name="children">
                <xsl:apply-templates select="key('child', atom[@name='irn'])"/>
             </tuple>
        </xsl:if>
    </tuple>
</xsl:template>

</xsl:stylesheet>

虽然这将对记录进行分组，但输出只是这些集合中的一个。所以从一个3524条记录的文件中，我得到了一个24条记录的集合

我尝试过用XSLT替换：

<xsl:template match="/table">
    <table name="ecatalogue">
        <collection>
            <xsl:apply-templates select="tuple[not(tuple[@name='AssParentObjectRef']/atom[@name='irn'])]"/>
        </collection>
    </table>
</xsl:template>

与：

虽然这会返回所有嵌套结构，但它也会复制嵌套中的记录，从而使它们本身成为集合

你知道我哪里出错了吗

2017年6月6日编辑

当我使用：

<xsl:template match="node()|@*">
       <xsl:copy>
         <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
    </xsl:template>

我得到了重复项（注意：下面示例中的“id”已添加以供说明）：

是否仍有删除重复项的方法，以便只剩下嵌套记录

                    This is vaguely annalogous to your use of `key`. -->

                <!-- Finding the top-level `tuple` is complicated by the fact that the ID values in 
                    `<atom name="irn">` do not have a standardized format, other than that the whole
                    strings appear to consist of atomic values separated by single periods, with 
                    descendant `irn` values appending to the precedent values.  Examples:
                      Top:        `da.04`
                      Descendant: `da.04.11.02`
                      Top:        `D42.PL.05`
                      Descendant: `D42.PL.05.01`
                    So chunking the ID values is a problematic approach, since we don't know how many
                    chunks comprise the initial non-numeric portion: `da`, or `D42.PL`, or ... ???.
                    Top-level elements *do* also have empty `<tuple name="AssParentObjectRef">` elements.
                    So we _can_ find all the top-level elements, and then look in those for the one that
                    has an `irn` value that matches the start of the `irn` value of this current `tuple`. -->

                      The below statement then goes through all those `tuple`s to find the ones where the `irn`
                      values match the start of the `irn` value of the current `tuple`.']
