  Using the following XML, do you know how to retrieve the value of PrintDestination?

  i.e I need to return

  CH3001

  <MyXmlData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="MyXml.xsd" RequestId="D9E4EBA6-5E29-4206-929C-33594AA7F713" PrintDestination="CH3001" PrintPriority="5">

  <SalesChannel>A03</SalesChannel>

  </MyXmlData>'

  Thanks in advance.

  Is there any particular language that you are looking to accomplish this in? I have some examples in both VB.Net and C#, with the C# example being much clearer. I just completed a blog post about parsing XML using C# and Linq to XML. You can read about it here[/url].

  not sure exactly what you are looking for, but here is one possible answer

  declare @xml as xml = '<MyXmlData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="MyXml.xsd" RequestId="D9E4EBA6-5E29-4206-929C-33594AA7F713" PrintDestination="CH3001" PrintPriority="5">

  <SalesChannel>A03</SalesChannel>

  </MyXmlData>'

  select @xml.query('let $s := .

  return data($s/MyXmlData/@PrintDestination)')

  Thanks everyone for your feedback ... I'm always amazed at how I think I'm clear in my communications but often find others are not clear on my intent. In T-SQL I need to extract the value for the PrintDestination attribute, which is an attribute of the root element.

  !2Brite, you hit it right on the head ... this was just what I needed. I wrestled with this problem for hours and couldn’t figure it out. Thank you very much.

  You might also be interested in this other method:

  declare @myXml xml

  set @myXml = '

  <MyXmlData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="MyXml.xsd" RequestId="D9E4EBA6-5E29-4206-929C-33594AA7F713" PrintDestination="CH3001" PrintPriority="5">

  <SalesChannel>A03</SalesChannel>

  </MyXmlData>'

  select @myXml.value('MyXmlData[1]/@PrintDestination','varchar(20)')
