How to filter out elements in a tHMap SimpleLoop

kknoon — Wed, 05 Jul 2017 23:11:53 GMT

I'm fairly new to Talend. I have a Job that convert JSON to XML using a tHMap. In the mapper, under each JSON record I have an sub array of "providers" as input that output to
"xml_providers". I'm using a SimpleLoop to iterate over "providers" specified by a sort. All works ok so far.

The challenge is to not emit (or filter out) some of the "providers" based on certain criteria in a Java function:

public static boolean includeProvider(currentProviderInLoop, providers) {

}

I have looked at Filter -> isValid and ValidateGroup but nothing is working.

I couldn't find any working example or online (with images) on how to accomplish that.

Hi,

You could use the filter of your simple loop.

That's what I've been trying to use. But isn't any good example anywhere, something with step by step screenshots.
