How do I populate a DataSet from a XML string?

I have a string containing valid XML.
How do I populate a dataset based on the string, without reference to an XML
schema or writing the XML to file and reading it back in again?

You need an XML schema I think that describes the structure of the XML,
then it is no problem to read in the XML into an XmlDataDocument . But
without a schema it is not possible to associate the XML with a DataSet,
whether the XML is read from a file or from a string doesn't really matter.

Hi - I think I've cracked it - the following code seems to work:

Public Shared Function bDSOpenFromXML( ByVal vsXML As String, ByRef wdsReturn
As DataSet) As Boolean
' Creates a dataset based on the specified XML string
' Returns true for success

Dim rdr As New System.IO.Strin gReader(vsXML)
wdsReturn = New DataSet
wdsReturn.ReadX ml(rdr)

bDSOpenFromXML = True
End Function

I have successfully loaded a DataSet object with a XML schema (XSD). Now I wish to populate the tables that was created in the DataSet. I have an XML file/string that contain all the needed data in the same format as the XSD (the XML file/string was created using this same schema). The XML file/string may contain data for a single table or for several tables at once. The question is:

Hi, We are in the process of designing an ASP.NET app, where a user will enter some 'Customer ID' to be queried in the database.

I have 4 different databases that I'm having to pull data from in order to populate a datagrid. I am able to do this, but my problem is that because I'm pulling the data from 4 different databases, the data is ordered alphabetically but is grouped by database.

When I check the syntax of dataset, It seems that dataset can only read data from file. (e.g., datset.read(string filename), dataset.readxml(string filename)). If I have a string with XML format that is transfered from somewhere else, how can I read the string and populate it into a dataset, then display the data in a data grid? Thanks for any help.
