The following should do the trick
ToExpression/@ReadList[filename, Word,
RecordLists -> True, RecordSeparators -> {{"<"}, {">\n"}}]
Note, this assumes none of the numbers are formatted as
2.5e-03
or
2.5E-03
While ToExpression will convert these to an expression, it will not be what you are expecting.
