HI @linoshi
Content being a very large XML field, and you can't access it directly however there is a trick if you have to have it in a workflow, it is to export it in a file and load the same file straight after the export. it was done as a test / PoC very years back and the file format used was tabulation as a delimiter and in the file load activity, it is to set the field as Long Text and that records spam on multiple line...
Otherwise, you could use a JavaScript activity to get access to the information, depending of your use case that would work too...
If the use case is purely technical for technical audience, then JS is one route, if the use case is business centered, aka use by marketers, although the export/import is slight awkward, I would use that route as it uses standard workflow activities that marketers can understand...
Thanks
Denis
