What’s New in XML Merge 11.0.0 & DITA Merge 7.0.0
Last summer, we released XML Compare 12.0.0, which featured a new, improved algorithm for table comparison. This new approach leads to more precise, more intuitive and more detailed change representation in tables where one or more of the following changes have taken place:
- Column span changes
- Row span changes
- Column order change
- Row order change
It also adds the ability to ignore the order of columns, which means that a change in order doesn’t trigger delta markup in the result.
We’re excited to announce that with XML Merge 11.0.0 and DITA Merge 7.0.0, the new table algorithm is now available in our merge products as well.
Two-way table comparison is complicated enough, and extending that to n-way comparison has been a challenge! But we’re confident that this update will improve your merge results and make it easier to produce a single, resolved table merge if that’s your final output target.
Please note that we have kept both versions of the table processing in XML Merge 11. To use the new processing, you will need to enable it using the appropriate parameter settings. This allows you to test the new approach before using it in production.
The new table algorithm is currently only available in ConcurrentMerge.
How do we display structure changes?
If some of the table versions have different structures, we have to select a ‘master’ table from which to create the result. We use the Merge version priority to determine which version to use as the master. The spans in that version are prioritised, and other spans are created around them, sometimes as they were in the original and sometimes fragmented as necessary to ensure table validity. This approach helps to keep the result table as compact as possible while still representing how the table content has changed.
What do the new results look like?
The following examples demonstrate some of the improved results that the new table processing produces. The colouring in the screenshots is added to visualise the different versions and is based on the delta values in the XML result.
