Extract numeric values from XML for use in query

Hi all,

I need to extract ID values from an XML string and use those NUMERIC values in a query. I need something like
FROM myTable
WHERE ID IN (List_of_values_from_XML)

I have been playing around with ExtractValue(), but, this function returns a string, and even if I replace the spaces with commas, it still is a string and not a comma separated list.
This here

FROM myTable
WHERE ID IN (replace(ExtractValue(myXML, '/root/elem@ID'), ' ', ','));

will obviously return only the first matching record of myTable.

What I would like even better than a comma separated list, would be some kind of recordset or virtual table that I could join to myTable. (In MSSQL you can use OPENXML() like this.)

Are there any ways to do one of these in MySQL?

Thank you in advance,
