If the user defined two or more replacement rules, the transformer performs every replacement in the order from top to bottom.

Improve StringReplacer to allow Multiple String Replacements
- Contributor
For example, if you need to replace suffix {a, b, c} with {x, y, z}, you will have to use three StringReplacers with different regular expressions. In this example, the StringPairReplacer cannot be used since the source string contains a, b, c within the non-suffix part.
I think the StringReplacer has a room to improve to allow users to define one or more replacement rules. Probably the parameters setting for the above example looks like this.

Two other potential improvements:
Allow the stringReplacer to use List Attributes directly.
Optionally return an attribute with statistics (3 replacements were made)

Have you tried using conditional values here?
For example, using takashi's scenario, you should be able to replace the StringReplacers with a single AttributeManager. The value is set to conditional (eg if attribute ends-in a) and uses a regex function in the text editor (@ReplaceRegEx(attribute,$a,x))
See this example:

@takashi Do you know of any other applications that offer this type of functionality that we could use as a

This is great if your attribute only meets one of the conditions, what about if your attribute meets 2 or more conditions?

You can set up conditions to be AND or OR statements (or a mix of both) so you can hopefully use those to set up multiple conditions in any way you need. The first condition that is met, is the one that applies, so if you want to apply more than one result, then you'd need to use a separate line in the AttributeManager, or use a series of transformers.

A small improvement with the StringPairReplacer would be to be able to use an attribute for Replacement Pairs

This would be so useful - I quite often look for other solutions than using multiple StringReplacers.

@Takashi Iijima Thanks for sharing an idea. I tried creating a custom transformer for it.
Hope this works !
