How to access a xml node with attributes and namespace using selectsinglenode()

I have an XML:

<Root xmlns:XXXlocal="XXXX" schemaVersion="2.7" variant="multiterm">
  <Customers>
    <Customer type="Covered">
      <DataItem name="OpCity" value="" />
      <DataItem name="OpAddress1" value="" />
      <DataItem name="OpAddress2" value="" />
      <DataItem name="OpState" value="MI" />
    <Customer>
  </Customers>
</Root>

I need to get the value “MI” from the above XML. Please note that the XML has many different “Customer Types.”

How would I go about doing this? I’m having difficulty writing the xPath query to get it.

In C#, you can use LINQ/XDocument, and XPathSelectElement() to query with xpath:

var document = XDocument.Load(fileName);
var namespaceManager = new XmlNamespaceManager(new NameTable());
namespaceManager.AddNamespace("l", "XXXX");
var val = document.XPathSelectElement("/l:Root/l:Customers/l:Customer[@type='Covered']/l:DataItem[@name='OpState']/@value", namespaceManager).Value;
