Nach dem, was ich gesammelt habe, suchen Sie nach einer Möglichkeit, Unterschiede im Text hervorzuheben, um die Unterschiede zwischen den Beschreibungen zu erkennen. Von dort aus darf ich vorschlagen, dass Sie die Diff-Funktion auf nur b_discription beschränken da die anderen Attribute nicht im Rahmen Ihrer Anforderungen zu liegen scheinen. Erwarten Sie business_logo , business_name oder mod_date geändert werden? Unabhängig davon kann die folgende Funktion über alle Attribute in Ihrem Objekt ausgeführt werden, wenn sie in einen String konvertiert werden können.
simplediff ist ein ausgezeichnetes Skript, das den Unterschied zwischen zwei Zeichenfolgen findet, einschließlich:
- Existiert in A und nicht in B (Löschung)
- Existiert in B und nicht in A (Einfügung)
