String Comparison

The input will contain two columns containing strings. The comparison of the strings is returned as HTML where deleted characters are highlighted in red and inserted characters are highlighted in green.

This node uses the algorithm from googles diff-match-patch library. Specifically the forked version published to maven central is used.

Additional information on the change is provided in terms of counts of character insertions, deletions and equality. These counts are simply how many characters are in the text for deletion elements, how many are in the text for insertion elements and finally how many are in the text for equal elements. The % change is simply the proportion of characters in the deletion and insertion vs the equal diff elements.

Cleanup Method Options:

• NONE - No cleanup method applied.
• EFFICIENCY - Increase computational efficiency by factoring out short commonalities which are not worth the overhead.
• SEMANTIC - Increase human readability by factoring out commonalities which are likely to be coincidental.
• SEMANTIC_LOSSLESS - Looks for single edits surrounded on both sides by equalities which can be shifted sideways to align the edit to a word boundary.
