Do you have to use the Import and export wizard it can be achived in a few lines of code, for example importing a xmlfile into a column of a table:
INSERT INTO T(XmlCol)
SELECT * FROM OPENROWSET(
BULK 'c:\SampleFolder\SampleData3.txt',
SINGLE_BLOB) AS x;
taken from this article: http://technet.microsoft.com/en-us/library/ms191184.aspx
Once imported to a coluns you can shred the data to columns or perform xquery commands on it etc.
