Use XQuery to Get This Data

I am new to XQuery and I have some problems with it. Here is my example.

I have this variable:

declare @xmlDoc XML

it stores the following xml:

<?xml version="1.0" encoding="utf-8"?>
<NewDataSet>
  <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
    <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:Locale="">
      <xs:complexType>
        <xs:choice minOccurs="0" maxOccurs="unbounded">
          <xs:element name="Table1">
            <xs:complexType>
              <xs:sequence>
                <xs:element name="Sharedparam" type="xs:string" minOccurs="0" />
                <xs:element name="Antoher" type="xs:string" minOccurs="0" />
                <xs:element name="RandomParam2" type="xs:string" minOccurs="0" />
                <xs:element name="MoreParam" type="xs:string" minOccurs="0" />
                <xs:element name="ResultsParam" type="xs:string" minOccurs="0" />
              </xs:sequence>
            </xs:complexType>
          </xs:element>
        </xs:choice>
      </xs:complexType>
    </xs:element>
  </xs:schema>
  <Table1>
    <Sharedparam>shared</Sharedparam>
    <Antoher>sahre</Antoher>
    <RandomParam2>Good stuff</RandomParam2>
    <MoreParam>and more</MoreParam>
    <ResultsParam>2</ResultsParam>
  </Table1>
  <Table1>
    <Sharedparam>Hey</Sharedparam>
    <Antoher>what </Antoher>
    <RandomParam2>do you</RandomParam2>
    <MoreParam>think</MoreParam>
    <ResultsParam>2</ResultsParam>
  </Table1>
  <Table1 />
</NewDataSet>

How can I select all Sharedparam values? (Or really, any decent query that returns values โ€‹โ€‹(rather than xml) would be great.)

What I really want to do is get the result set as follows:

Name             Value1          Value2          Value3        Value4
Sharedparam      shared          Hey             Null          Null
Another          share           what            Null          Null
....

This would allow me to ignore any data outside of "Value4" (and this is acceptable for my use of this data).

Try something like this:

SELECT
    TBL.SParam.value('(.)[1]', 'varchar(50)')
FROM
    @xmldoc.nodes('/NewDataSet/Table1/Sharedparam') AS TBL(SParam)

Gives me the conclusion:

(No column name)
shared
Hey

:, XML <Table1>, XQuery:

SELECT
    TBL.SParam.value('local-name(.)[1]', 'varchar(50)') 'Attribute',
    TBL.SParam.value('(.)[1]', 'varchar(50)') 'Value'
FROM
    @xmldoc.nodes('/NewDataSet/Table1/*') AS TBL(SParam)

:

Sharedparam          shared

SELECT

    TBL.SParam.value('(.)[1]', 'varchar(50)') 'Value 1',
    TBL2.SParam2.value('(.)[1]', 'varchar(50)') 'Value 2'
FROM
    @xmldoc.nodes('/NewDataSet/Table1[1]/*') AS TBL(SParam)
INNER JOIN
    @xmldoc.nodes('/NewDataSet/Table1[2]/*') AS TBL2(SParam2) ON TBL.SParam.value('local-name(.)[1]', 'varchar(50)') = TBL2.SParam2.value('local-name(.)[1]', 'varchar(50)')

:

. Sharedparam, Antoher ..: .

, Table1 maxOccurs="unbounded", = SQL,

( ), :

SELECT
   x.item.value('(Sharedparam)[1]', 'varchar(100)') AS Sharedparam,
   x.item.value('(Antoher)[1]', 'varchar(100)') AS Antoher,
   x.item.value('(SharedRandomParam2param)[1]', 'varchar(100)') AS RandomParam2,
   ...
FROM
   @xmlDoc.nodes('/NewDataSet/Table1') x(item)
