How to use User Defined Expression

Hello,
In Expression Builder there is a possibility to build User-Defined function. But I don't know how to build this and how the syntax should look like. I found in Expression Builder a possibility to import expression by giving an XML-File. But how should this XML look like?
My Target is to rebuild the Decode function with one user-defined function in Talend. Does anyone have an idee?. Thanks so much!!!

Re: How to use User Defined Expression

under the "Code" section of your repo (in the talend client) create a new routine. you can then use this routine in the expression builder.
