Your code is broadly correct. The only thing wrong with it is that
<browseList> is not, in your example, an ancestor of the relevant attribute
node. Also I think it would be clearer if you wrote
ancestor::something/browseList/MxColumn/text(). 

You haven't said what product you are using, as the failure is a ClassCast
it looks to me like a bug in the product.
