This doesn't seem to be working anymore. I'm running the latest Alfred v2.3 on OS X Yosemite Beta 5 and I tried it with Sublime Text 3 and TextEdit. The selected text seems to get copied, but the text editor doesn't open.
Thanks for the reply! but no, this is not quite what I'm looking for. The main part I'm having trouble with is accessing the returned XML from one workflow in another workflow.
Is it possible to call an external workflow from within a workflow then manipulate the external workflow's returned results before displaying them? For example, to have a global live search workflow that returns suggestions from several other live search workflows.
