Hi, all,


Read XML is one of my favorite operators in RM. One thing I have noticed, however, is that the results shown in the preview and the results once run are sometimes different. For example, the following works just fine in the preview:




However, it returns blank results when run. But when implemented using R (xpathSApply), it runs just fine.


Any thoughts on this?

    The same issue with Rapidminer 7.4 (Mac and Windows).


    What do you mean by "implemented using R (xpathSApply)"? You mean calling R from within Rapidminer?

    Yes, you can call R scripts from withing RapidMiner by using the R Scripting extension. Note, there's also an Python Scripting extension too.
