txmlmap loop with 0 elements

Hello community,

I've searched around but could not find the answer.

I have an XML structure shown on attachment.

The issue is when the repeatable items are not returned, then the document does not get created at all (as loop is kind of a row generator in Talend).

What is the best way to generate the document without the repeatable items ? THMap ? Split the document and then combine after mapping ?

So far I have a tExtractXML connected to tJavaFlex to count elements and two "Run if" triggers (for count == 0 and count > 0). That seems really complex and unnecessary.

Any suggestion appreciated.

Karol

Hi, have you try to set create empty element to true in the output of the tXmlMap?

Send me Love and Kudos.

Hi,

That does not help. It controls the output not the loop row generator.

Hi can you try loop optional instead of loop in the xmlmap input ?
