beginners filtering problem

Hi,

I'm having a little trouble getting to grips with sxpath and I wonder
if someone could help.  Given a node like this

(ItemDef (@ (SASFieldName "WTUNITS")
                    (OID "IT.WTUNITS") (Name "Weight Units")
                    (Length "2") (DataType "text")))

I'd like to get the text bits of the OID and Name attributes.

The following does what I want but I'm not sure its as simple as it could be

((sxpath '(*text*))
   ((node-or (sxpath '(@ OID))
             (sxpath '(@ Name))) (node obj))))

..where (node obj) evaluates to the node described above

I think that a solution involving the filter converter should make it
clearer but I haven't been able to get it to do what I mean.

I'm using guile's sxpath if that makes a difference.

Cheers,
Andy
