Query possible selections from dropdown

Hi,

I guess my problem is rather simple to solve for experienced xpath-ers.

I have a dropdown-control which is automatically filled (labels and values) when loading the form.
How am I able to query if a certain value or label is included in the possible selections? I tried different xpath-functions as collection or contains but they dont have the intended functionality. Thank you.

How can i find out which different values are in a dropdown-control?

Thanks, Christian

Hi Christian,

You can use the xxf:itemset() XPath function for this. For instance, if you have a control named 'a', you can get its items with xxf:itemset('a-control', 'xml')/itemset/choices/item. (Note the '-control' after the control name, as this function takes a control id, and this is how Form Builder generates controls ids from the name you entered.) And for more on the format of the data returned by xxf:itemset(), see:
