[xsl] XPath: all elements with only non-parent children with identical style attr

[Tobias Reif <tobiasreif at pinkjuice dot com>]

Hi,

I'm looking for an XPath which returns all elements that
   * have only children that are no parents
     (= have no children @ all: no textnodes, no whitespace nodes, etc)
     * all of those (diverse) children have a style attribute with
       the exact same value

so that from

<root>
   <foo>
    <bar style="baz"/>
    <blah style="baz"/>
    <blam style="baz"/>
   </foo>
</root>

element foo would be returned.

TIA,
Tobi
