Conditional Expressions in Forms

Forms
Updated September 9, 2015
asked on September 9, 2015

In the Forms help documentation here, it talks about how to use conditional expressions in Forms. One of the examples it shows is to change the statement to the following "matches(/dataset/attribute_name, "value")", but it does not give an explanation of what that does? Does it allow you to include multiple values it has to match on or how is it different than "/dataset/single_line= "value")"? Also, are there other options other than "matches" we can use?

Here is a link to an XPath tutorial and a list of functions you can use. To answer the question about what's different between using matches() and the equal sign (=), the equal sign is case sensitive whereas matches() is case insensitive.

If you're looking to match against multiple values, you can use "or" in between the conditions.
