You should be getting a text node with content formed from the string
values of the ishfield elements making up the sequence of ishfield
elements where the name attribute value is FTITLE separated by spaces.

Are you sure the ishfield elements have string values? (that is,
descendent text nodes?)

What happens when you replace value-of with sequence?
