If you want a single-line data file for survey data, why don't you use the <survey> element? A <survey> element is a special type of <block> and can be run via the <expt> element's /blocks attribute.Note, though, that you *don't* want to use <survey> elements if you happen to repeat some <surveypage> elements or question elements over an over. How could that be captured in a single line file? Single-line survey data provides *one column per question*, thus different responses to repeated instances of a given question element simply cannot be captured that way.Instead, you need to re-structure / aggregate your data using your preferred data management / statistical analysis application. All of them provide facilities to do so -- such data preparation it is a routine task in the course of most computerized data collection and research.Edited to add: Example for the above -- observe the differences between the 3 resulting data files and how they correspond to the respective <survey>s vs. <block> setup.
