  I am currently trying to parse the following XML using the following T-SQL code

  DECLARE @XML XML = '<?xml version="1.0"?>

  <root triggerEvent="UserChanged" xmlns="http://www.xyz.com">

  <AdminAudit_Ext>

  <ApplicationName>CC</ApplicationName>

  <ModifiedByUserID>su</ModifiedByUserID>

  <ModifiedByUserName>Super User</ModifiedByUserName>

  <ModifiedDate>2013-11-14T11:16:07.55-05:00</ModifiedDate>

  <ModifiedEntityID>1474</ModifiedEntityID>

  <ModifiedEntityName>User</ModifiedEntityName>

  <ModifiedEntityPublicID>test:30810</ModifiedEntityPublicID>

  <ModifiedFieldName>UserRole</ModifiedFieldName>

  <ModifiedObjectName>USER 1</ModifiedObjectName>

  <NewValue>Superuser</NewValue>

  </AdminAudit_Ext>

  </root>'

  SELECT Y.ID.value('(@triggerEvent)[1]', 'varchar(100)')

  FROM @xml.nodes('/root') Y(ID)

  and it is returning 0 rows. I am stumped as to what I am doing wrong. Can someone please provide me some insight?

  Thanks,

  Michael

  The tricky part is the namespace declaration xmlns="http://www.xyz.com".

  This will force you to use the namespace within your query as well.

  The followingcode shoud work:

  ;

  WITH XMLNAMESPACES ('http://www.xyz.com' as ns)

  SELECT t.c.value('(@triggerEvent)[1]', 'varchar(100)')

  FROM @XML.nodes('/ns:root') t(c)

  Thanks!....that worked beautifully...but now when I try to run the following SQL, I get nothing. I know I suck at this XML parsing, so I appreciate the help

  ;WITH XMLNAMESPACES ('http://www.xyz.com' as ns)

  SELECT

  Y.ID.value('(@triggerEvent)[1]', 'varchar(100)') ,

  Y.ID.value('(ApplicationName)[1]', 'varchar(100)')

  FROM @xml.nodes('//ns:root/AdminAudit_Ext') Y(ID)

  Try this (notice I also changed the namespace declaration to use a default instead so you don't need to prefix things with "ns:")

  ;with xmlnamespaces ( default 'http://www.xyz.com')

  SELECT

  Y.ID.value('(@triggerEvent)[1]', 'varchar(100)')

  ,Y.ID.value('(AdminAudit_Ext/ApplicationName/text())[1]','varchar(100)')

  FROM @xml.nodes('/root') Y(ID)
