XML in SQL - Query

Hi. I have a table which looks like this

ID (as uniqueidentifier) - key
Date (as datetime)
XMLFile (as XML)


The XML file is much worse composed, it is basically a snapshot of data at some point in time

It looks something like The code at the bottom but MUCH MUCH longer (yay):

As you notice, each xml file has multiple members
And the subnodes (ident) are NOT in order or sometimes missing altogether

I need to write a simple query,
The pseudocode is

SELECT  XMLFILE.value(/root//...ident/qualifier/identification (WHARE QUALIFIER = AAA))
FROM TABLE
WHERE XMLFILE.value(/root//....(Membernum = 0000001 OR 0000002  )



<root>
  <identity>0000001</identity>
    <member>
    <membernum>0000001</membernum>
    <identities>
      <ident>
        <qualifier>1</qualifier>
        <identification>0000001</identification>
      </ident>
      <ident>
        <qualifier>Name</qualifier>
        <identification>George Forman</identification>
      </ident>
      <ident>
        <qualifier>State</qualifier>
        <identification>Confusion</identification>
      </ident>
      <ident>
        <qualifier>AAA</qualifier>
        <identification>ABC123</identification>
      </ident>
    </identities>
    <member>
    <membernum>0000002</membernum>
    <identities>
      <ident>
        <qualifier>Name</qualifier>
        <identification>Alexander Bell</identification>
      </ident>
      <ident>
        <qualifier>State</qualifier>
        <identification>Dilusion</identification>
      </ident>
      <ident>
        <qualifier>AAA</qualifier>
        <identification>ABC12345</identification>
      </ident>
    </identities>
  </member>

That is not a well-formed Xml document.  Do you mean:
<root>
      <identity>0000001</identity>
      <member>
            <membernum>0000001</membernum>
            <identities>
                  <ident>
                  <qualifier>1</qualifier>
                  <identification>0000001</identification>
                  </ident>
                  <ident>
                  <qualifier>Name</qualifier>
                  <identification>George Forman</identification>
                  </ident>
                  <ident>
                  <qualifier>State</qualifier>
                  <identification>Confusion</identification>
                  </ident>
                  <ident>
                  <qualifier>AAA</qualifier>
                  <identification>ABC123</identification>
                  </ident>
            </identities>
     </member>
      <member>
            <membernum>0000002</membernum>
            <identities>
              <ident>
                  <qualifier>Name</qualifier>
                  <identification>Alexander Bell</identification>
              </ident>
              <ident>
                  <qualifier>State</qualifier>
                  <identification>Dilusion</identification>
              </ident>
              <ident>
                  <qualifier>AAA</qualifier>
                  <identification>ABC12345</identification>
              </ident>
            </identities>
      </member>
</root>

You can do something like this:
SELECT  t.c.value('.', 'varchar(20)')
FROM    @YourTable
        CROSS APPLY XmlFile.nodes('root/member/identities/ident/identification[../../../membernum = "0000001" or ../../../membernum = "0000002"]') T (C)

This is how I tested it:
DECLARE @YourTable TABLE (XmlFile xml NOT NULL)

INSERT @YourTable (XmlFile)
VALUES  (
'<root>
      <identity>0000001</identity>
      <member>
            <membernum>0000001</membernum>
            <identities>
                  <ident>
                  <qualifier>1</qualifier>
                  <identification>0000001</identification>
                  </ident>
                  <ident>
                  <qualifier>Name</qualifier>
                  <identification>George Forman</identification>
                  </ident>
                  <ident>
                  <qualifier>State</qualifier>
                  <identification>Confusion</identification>
                  </ident>
                  <ident>
                  <qualifier>AAA</qualifier>
                  <identification>ABC123</identification>
                  </ident>
            </identities>
     </member>
      <member>
            <membernum>0000002</membernum>
            <identities>
              <ident>
                  <qualifier>Name</qualifier>
                  <identification>Alexander Bell</identification>
              </ident>
              <ident>
                  <qualifier>State</qualifier>
                  <identification>Dilusion</identification>
              </ident>
              <ident>
                  <qualifier>AAA</qualifier>
                  <identification>ABC12345</identification>
              </ident>
            </identities>
      </member>
</root>')

SELECT  t.c.value('.', 'varchar(20)')
FROM    @YourTable
        CROSS APPLY XmlFile.nodes('root/member/identities/ident/identification[../../../membernum = "0000001" or ../../../membernum = "0000002"]') T (C)

Output:
0000001
George Forman
Confusion
ABC123
Alexander Bell
Dilusion
ABC12345
