Empty XML file generation

[HIrena]

Hello,

Not really an issue, but is it possible to generate an xml from an existing from-select structure? Creating manually xmls to use paired with a <if-missing> feature could be troublesome.

Thank you!

Fair feedback, creating empty files is boring and not so straightforward.

I propose to add a if-unavailable element in a result-set to specify another result-set if the first one is failing. At the moment, I'll just activate this feature in case an xml-source is failing but feel free to give me some feedback and check if we cannot generalize.

In addition, I'll create a new child element of result-set named empty and accepting an attribute column-count or a list of column-names.

Combining these two new features, it should be easier to create an empty result-set when something is going wrong into your xml-source.

• new element empty for a result-set
• new element if-unavailable for a result-set
