runX :: IOSArrow XmlTree c -> IO [c]

apply an IOSArrow to an empty root node with initialState () as initial state

the main entry point for running a state arrow with IO

when running runX f an empty XML root node is applied to f. usually f will start with a constant arrow (ignoring the input), e.g. a Text.XML.HXT.Arrow.ReadDocument.readDocument arrow.

for usage see examples with Text.XML.HXT.Arrow.WriteDocument.writeDocument

if input has to be feed into the arrow use runIOSLA like in runIOSLA f emptyX inputDoc
