How to query values from xml nodes?

Question

i have a table that contains an XML column:

CREATE TABLE Batches( 
   BatchID int,
   RawXml xml 
)

The xml contains items such as:

<GrobReportXmlFileXmlFile>
   <GrobReport>
       <ReportHeader>
          <OrganizationReportReferenceIdentifier>1</OrganizationReportReferenceIdentifier>
          <OrganizationNumber>4</OrganizationNumber>
       </ReportHeader>
  </GrobReport>
   <GrobReport>
       <ReportHeader>
          <OrganizationReportReferenceIdentifier>2</OrganizationReportReferenceIdentifier>
          <OrganizationNumber>4</OrganizationNumber>
       </ReportHeader>
  </GrobReport>
   <GrobReport>
       <ReportHeader>
          <OrganizationReportReferenceIdentifier>3</OrganizationReportReferenceIdentifier>
          <OrganizationNumber>4</OrganizationNumber>
       </ReportHeader>
  </GrobReport>
   <GrobReport>
       <ReportHeader>
          <OrganizationReportReferenceIdentifier>4</OrganizationReportReferenceIdentifier>
          <OrganizationNumber>4</OrganizationNumber>
       </ReportHeader>
  </GrobReport>

What i want is to generate a set, that contains:

OrganizationReportReferenceNumber  OrganizationNumber
=================================  ==================
1                                  4
2                                  4
3                                  4
4                                  4

i've tried:

SELECT 
    foo.value('/ReportHeader/OrganizationReportReferenceIdentifier') AS ReportIdentifierNumber,
    foo.value('/ReportHeader/OrganizationNumber') AS OrginazationNumber
FROM CDRBatches.RawXML.query('/GrobReportXmlFileXmlFile/GrobReport/ReportHeader') foo

but that doesn't work. i've tried:

SELECT 
    foo.value('/ReportHeader/OrganizationReportReferenceIdentifier') AS ReportIdentifierNumber,
    foo.value('/ReportHeader/OrganizationNumber') AS OrginazationNumber
FROM RawXML.nodes('/GrobReportXmlFileXmlFile/GrobReport/ReportHeader') bar(foo)

But that doesn't work. The XPath expression

/GrobReportXmlFileXmlFile/GrobReport/ReportHeader

is correct; in any other xml system it returns:

<ReportHeader>
    <OrganizationReportReferenceIdentifier>1</OrganizationReportReferenceIdentifier>
    <OrganizationNumber>4</OrganizationNumber>
</ReportHeader>
<ReportHeader>
    <OrganizationReportReferenceIdentifier>2</OrganizationReportReferenceIdentifier>
    <OrganizationNumber>4</OrganizationNumber>
</ReportHeader>
<ReportHeader>
    <OrganizationReportReferenceIdentifier>3</OrganizationReportReferenceIdentifier>
    <OrganizationNumber>4</OrganizationNumber>
</ReportHeader>
<ReportHeader>
    <OrganizationReportReferenceIdentifier>4</OrganizationReportReferenceIdentifier>
    <OrganizationNumber>4</OrganizationNumber>
</ReportHeader>

So, it's obvious from my queries that i'd like to see. After reading a dozen Stackover questions and answers, i'm no closer to solving the problem.

SELECT  b.BatchID,
        x.XmlCol.value('(ReportHeader/OrganizationReportReferenceIdentifier)[1]','VARCHAR(100)') AS OrganizationReportReferenceIdentifier,
        x.XmlCol.value('(ReportHeader/OrganizationNumber)[1]','VARCHAR(100)') AS OrganizationNumber
FROM    Batches b
CROSS APPLY b.RawXml.nodes('/CasinoDisbursementReportXmlFile/CasinoDisbursementReport') x(XmlCol);
