SQL XML - Read value from xml column












0















I'm having trouble to query an xml from the database.
The original column in the database is of the type ntext, but an xml text is stored in this column.
When I cast the column to xml type, this is one of the results:



<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.desoft.de/activerepo/fileprops">
<props>
<prop ns="ARM:" elem="_NoFilter">
<value xsi:type="xsd:boolean">true</value>
</prop>
<prop ns="DAV:" elem="displayname">
<value xsi:type="xsd:string">RE: Demande de Rendez vous pour le 31 Janvier</value>
</prop>
<prop ns="DAV:" elem="getcontenttype">
<value xsi:type="xsd:string">message/rfc822</value>
</prop>
<prop ns="DAV:" elem="creationdate">
<value xsi:type="xsd:dateTime">2018-10-18T18:41:41.3993879</value>
</prop>
<prop ns="tm:mail:" elem="account">
<value xsi:type="xsd:string">mailjournal@gg.com</value>
</prop>
<prop ns="tm:mail:" elem="journal">
<value xsi:type="xsd:boolean">true</value>
</prop>
<prop ns="tm:mail:" elem="box">
<value xsi:type="xsd:string">Inbox</value>
</prop>
<prop ns="tm:mail:" elem="onlyattachments">
<value xsi:type="xsd:boolean">false</value>
</prop>
<prop ns="tm:mail:" elem="user">
<value xsi:type="xsd:string">mailjournal@gg.com</value>
</prop>
<prop ns="urn:schemas:httpmail:" elem="attachments">
<value xsi:type="xsd:boolean">true</value>
</prop>
...
</props>
</root>


Now I have to read single node values from the xml column, but actually this does not work and I don't know why.



select
top 10
cast(properties as xml),
cast(properties as xml).value('(/props/prop[@elem="displayname"]/value)[1]', 'nvarchar(255)') as testRead,
*
from
tm_cas_files f (nolock)
where
properties is not null
and id = '64A663EF-A466-4EB0-97DC-94554ADFDFC9'


If I try to read the xml this way, the column testRead is always null.
Any hints for me? Thanks in advance for your comments and help.

You need to declare your default namespace here, as it's declared in your XML. This gets you the result you want:



CREATE TABLE dbo.SampleTable (nXML ntext);
INSERT INTO dbo.SampleTable (nXML)
VALUES
(N'<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.desoft.de/activerepo/fileprops">

I've now made it work with your clues. The additional problem was that there were line breaks in the XML text. These had to be removed as well. Also the xml declaration was part of the text. This I removed as well. Then it worked. Here is the final code:



WITH XMLNAMESPACES(DEFAULT 'http://www.desoft.de/activerepo/fileprops', 'http://www.w3.org/2001/XMLSchema-instance' AS xsi,'http://www.w3.org/2001/XMLSchema' AS xsd)
select
top 10
cast(replace(replace(cast(properties as nvarchar(max)),CHAR(13) + CHAR(10),''),'<?xml version="1.0" encoding="utf-16"?>','') as xml).value('(root/props/prop[@elem="from"]/value)[1]', 'nvarchar(max)')
from
tm_cas_files f (nolock)
where
properties is not null
and id = '64A663EF-A466-4EB0-97DC-94554ADFDFC9'


Thanks very much for your help!

    Using XMLQuire to play with your xml tells me that the path to your answer starts with root :



    /root/props/prop[2]/value


    so you want '(/root/props/prop[@elem="displayname"]/value)[1]'



    XMLQuire has point-and-click 'show me the XPAth'

    • You're never going to get a non-null result out of the SQL if the xpath is wrong?

      – Chris F Carroll
      Nov 21 '18 at 9:45











    • No, that isn't true. If you use the wrong namespace, you will. If you take my answer, and comment out the line starting WITH XMLNAMESPACES, the return value will be NULL. But this answer doesn't help the OP on how to use XQuery, just tells them the node that the value is in. There's no detail on how they would get that value from the xml afterwards.

    • @Larnu I agree that the namespace is missing and yes that will also prevent a result. Equally, saying that the namespace is missing but ignoring the incorrect path is also only half way there? Secondly, a point-and-click tool saves hours when still on the xml learning curve.

    You need to declare your default namespace here, as it's declared in your XML. This gets you the result you want:

    I've now made it work with your clues. The additional problem was that there were line breaks in the XML text. These had to be removed as well. Also the xml declaration was part of the text. This I removed as well. Then it worked. Here is the final code:



    WITH XMLNAMESPACES(DEFAULT 'http://www.desoft.de/activerepo/fileprops', 'http://www.w3.org/2001/XMLSchema-instance' AS xsi,'http://www.w3.org/2001/XMLSchema' AS xsd)
    select
    top 10
    cast(replace(replace(cast(properties as nvarchar(max)),CHAR(13) + CHAR(10),''),'<?xml version="1.0" encoding="utf-16"?>','') as xml).value('(root/props/prop[@elem="from"]/value)[1]', 'nvarchar(max)')
    from
    tm_cas_files f (nolock)
    where
    properties is not null
    and id = '64A663EF-A466-4EB0-97DC-94554ADFDFC9'

            • @Larnu I agree that the namespace is missing and yes that will also prevent a result. Equally, saying that the namespace is missing but ignoring the incorrect path is also only half way there? Secondly, a point-and-click tool saves hours when still on the xml learning curve.

            • You're never going to get a non-null result out of the SQL if the xpath is wrong?

            • No, that isn't true. If you use the wrong namespace, you will. If you take my answer, and comment out the line starting WITH XMLNAMESPACES, the return value will be NULL. But this answer doesn't help the OP on how to use XQuery, just tells them the node that the value is in. There's no detail on how they would get that value from the xml afterwards.

            • @Larnu I agree that the namespace is missing and yes that will also prevent a result. Equally, saying that the namespace is missing but ignoring the incorrect path is also only half way there? Secondly, a point-and-click tool saves hours when still on the xml learning curve.
