We are currently in the process of upgrading our Aspose.cells dll from 8.1 to 17.9. The problem is that we use the cells dll to convert from excel spreadsheets to html and then parse the resultant html pages with xpath. The first question is, is it possible, for backwards compatibility, to run two versions of the cells dll in the same application and decide in my .net c# code which version of the converter I want to use?
The second question is, how likely is it that the new version of the software will significantly change the resultant html from the conversion in a way that would make parsing the xhtml structure with my existing xPaths break?
