Populate datagrid from XML file using where type query

I am able to populate a datagrid from an XML variable using the
following:

Try
Dim ds As New DataSet
ds.ReadXml(New
StringReader(HttpContext.Current.Application("var").ToString))
dataMeet.DataSource = ds
dataMeet.DataBind()
Catch ex As Exception
error_email.fncErrorHandler(ex)
lblError.Text = ex.ToString
End Try

however this does not allow me to use a sql type query to select
exactly the data I want in the datagrid.

The query I am looking to achieve is actually very simple, just a
simple 'where' but I have no idea how to achieve this when binding to
an xml variable

The sql query and a sample xml file are pasted below:

select TITLE, FIRST_NAME || ' ' || LAST_NAME AS FULL_NAME, DEPT, EMAIL,
PHONE FROM DATABASE.TABLE "
WHERE MEMBERTYPE_CODE = 'MEM' ORDER BY MEMBER_ID

<NewDataSet>
<Table>
<MEMBERTYPE_CODE>OFF</MEMBERTYPE_CODE>
<LAST_NAME>Smith</LAST_NAME>
<FIRST_NAME>Harry</FIRST_NAME>
<TITLE>engineer</TITLE>
<DEPT>engineering</DEPT>
<EMAIL>harry.smith@dotnet.itags.org.email.address</EMAIL>
<PHONE>(111) 111-1111</PHONE>
</Table>
<Table>
<MEMBERTYPE_CODE>MEM</MEMBERTYPE_CODE>
<LAST_NAME>fred</LAST_NAME>
<FIRST_NAME>bloggs</FIRST_NAME>
<TITLE>Webmaster</TITLE>
<DEPT>Information Technology Services</DEPT>
<EMAIL>fred.blogs@dotnet.itags.org.email.address</EMAIL>
<PHONE>(111) 111-1112</PHONE>
</Table>
</NewDataSet
Thank you for your timeHi gn,

You can use DataView's properties RowFilter and Sort to
perform functionality similar to 'WHERE' condition
and 'ORDER BY' in sql query. Following is sample code
snippet:

Dim dv As DataView = ds.Tables(0).DefaultView
dv.RowFilter = "MEMBERTYPE_CODE = 'MEM'"
dv.Sort = "LAST_NAME"
dataMeet.DataSource = dv
dataMeet.DataBind()
