How to retrieve element values from xml have multiple namespaces from SQL Server?

I was trying to retrieve hasFolder attribute values from below XML file and couldn't not working the query which i written. Could you help me to get the correct resultset.

Query which I have written is not working:

;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 data:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmlns:xmi="http://www.omg.org/XMI" xmi:version="2.0" 
         xmlns:rim="rochade:scanboxi:150"

Your namespaces are all nicely and properly set up - that is not the problem. But you're mixing attributes and elements. The question asks about the hasFolder attribute - but that's really an element with a bunch of attributes - and the code you show is actually trying to read the name attribute but is addressing it as if it were an element.

If you want to retrieve the name=... attribute from the <rim:Repository> element, then you need to use this 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

You need to indicate that you're interested in an attribute by putting a @ at the start of its name.

If you want to retrieve the whole <rim:hasFolder> element as an XML fragment, then you need to use this 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

Update: if you want to retrieve a single attribute from the <rim:hasFolder> element, use this syntax:

If you want to retrieve the whole <rim:hasFolder> element as an XML fragment, then you need to use this 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

and adapt as needed for other attributes
