Hello, I have a list view that uses an XPath contsraint to show it's values.  The list view is wrapped in a data view with a non-persistable entity as it's data source.  I use the non-persistable entity to filter the list view based on what the user fills out in a pop-up.  I want them to be able to apply multiple filters at the same time.   I can achieve this by using "AND" functions in the XPath constraint.  However, I can't get it to properly allow for list view items that have null values in one or more of the filterable fields.   So this is what I would like to put in the XPath constraint: IF $filter/Name = empty then don't include in XPath else $listview/Name = $filter/Name and IF $filter/City = empty then don't include in XPath else $listview/City = $filter/City and so on. . . Any ideas?
