I am having some problems with an XML transform and need some help.

The stylesheet should iterate through all suffix elements and place the contents without the suffix tag next to the last text node within its first ancestor quote-block element (see desired ouput). It works when only a single suffix is present, but not when 2 are present, when 2 are present it places both suffixes next to each other in the last text node of the first quote-block.

Any ideas? I have tried limiting the selections to ancestor::quote-block[1] in various places but that doesn't have the desired effect.
