Sorry, not following. If my filter consumes a stream, produces a
stream, and returns that stream, is it not still generating?
def filter_stream(self, req, method, filename, stream, formdata):
html = stream.render()
newstream = genshi.XML(html)
xpath_1 = '...'
xpath_2 = '...'
if 'magic word' in html:
return newstream | Transformer(xpath_1).remove()
else:
return newstream | Transformer(xpath_2).remove()
If it weren't a generator the plugin would not return content at all,
no? As it is the plugin returns content, it's just wrong because I
can't work out this conflict.
Maybe I mistake your point?
