【问题描述】：
我有一个可能有多个签名元素的 xml。我不知道每个根的签名元素的数量，但我需要按此元素分组，以便为每个根元素获得一行。
您认为使用价值方法可行吗？ 我已阅读 (Getting nth Element from last in a xml in Sql Server) 如何确定元素数量，但不允许在值方法中使用范围。
这是我的代码：
declare @xml as xml ='<root>
<Row>
<proceeding>
<signatures>XII GU 609/18</signatures>
<signatures>XII GUp 392/18</signatures>
<commissioner_name></commissioner_name>
<court_department>XII Wydział Gospodarczy</court_department>
<administrator_function>syndyk</administrator_function>
<court_name>Sąd Rejonowy w Gliwicach</court_name>
<administrator_name></administrator_name>
<commissioner_deputy_name />
<administrator_licence_number>920</administrator_licence_number>
</proceeding>
<msig_entry>
<chapter>0</chapter>

三个提示：感谢可执行示例，这是一个很大的帮助，但下次您可能会将其减少到所需的最低限度。第二：请添加预期的输出。您的问题尚不完全清楚...第三：请使用您的 RDBMS（供应商 和版本）进行标记。
[tsql]和代码指向[sql-server]，但 XML 支持是高度特定于产品的。 -
@Shnugo，感谢您的准确观察，实际上。我刚刚编辑了我的问题。
