Question

我试图从下面的XML文件中检索hasFolder属性值，并且无法处理我编写的查询。你能帮我找到正确的结果集吗？

我写的查询无效：

;with xmlnamespaces('http://www.omg.org/XMI' as xmi,
                    'rochade:scanboxi:150' as rim,
                    'http://www.asg.com/rochade/xml/xmiExtension/1.0' as rxe) 
select 
    data,
    data.value('(/xmi:XMI/rim:Repository/rim:name)[1]', 'varchar(max)')
from 
    Testxml

XML数据：

你的命名空间都设置得很好 - 这不是问题所在。但是你要混合属性和元素。该问题询问hasFolder属性 - 但这确实是一个带有大量属性的元素 - 您展示的代码实际上是在尝试阅读name 属性但正在解决它，好像它是一个元素。

如果您想从name=...元素中检索<rim:Repository> 属性，则需要使用此XQuery：

;with xmlnamespaces('http://www.omg.org/XMI' as xmi,
                    'rochade:scanboxi:150' as rim,
                    'http://www.asg.com/rochade/xml/xmiExtension/1.0' as rxe) 
select 
    data.value('(/xmi:XMI/rim:Repository/@rim:name)[1]', 'varchar(max)')
from 
    Testxml

您需要在其名称的开头添加@来表明您对属性感兴趣。

如果要将整个<rim:hasFolder> 元素检索为XML片段，则需要使用此XQuery：

;with xmlnamespaces('http://www.omg.org/XMI' as xmi,
                    'rochade:scanboxi:150' as rim,
                    'http://www.asg.com/rochade/xml/xmiExtension/1.0' as rxe) 
select 
    data.query('(/xmi:XMI/rim:Repository/rim:hasFolder)[1]')
from 
    Testxml

更新：如果您想从<rim:hasFolder>元素中检索单个属性，请使用以下语法：

如果要将整个<rim:hasFolder> 元素检索为XML片段，则需要使用此XQuery：

;with xmlnamespaces('http://www.omg.org/XMI' as xmi,
                    'rochade:scanboxi:150' as rim,
                    'http://www.asg.com/rochade/xml/xmiExtension/1.0' as rxe) 
select 
    data.value('(/xmi:XMI/rim:Repository/rim:hasFolder/@rim:name)[1]', 'varchar(200)')
from 
    Testxml

并根据需要调整其他属性

如何从xml中检索元素值有多个来自SQL Server的命名空间？
