MarkLogic: How to omit search facet values that are empty?

Using the default search endpoint and passing in an options file, I have a path range index set up on a particular element /path/to/my/element/.

I'm currently being returned the following in my facet:

<search:facet name="facetName" type="xs:string">
<search:facet-value name="" count="3"/>
<search:facet-value name="real value 1" count="1">real value 1</search:facet-value>
<search:facet-value name="real value 2" count="1">real value 2</search:facet-value>
</search:facet>

My desired output:

<search:facet name="facetName" type="xs:string">
<search:facet-value name="real value 1" count="1">real value 1</search:facet-value>
<search:facet-value name="real value 2" count="1">real value 2</search:facet-value>
</search:facet>

There's facet values being returned for empty elements, which I do not want. Is there a way to get rid of those empty facet values without having to write another transform to apply to the search results?

For desire output. You store generate output in variable and add condition as per mention below.

declare namespace search="http://www.search.com";

let $var1:=<search:facet name="facetName" type="xs:string">
              <search:facet-value name="" count="3"/>
              <search:facet-value name="real value 1" count="1">real value 1</search:facet-value>
              <search:facet-value name="real value 2" count="1">real value 2</search:facet-value>
            </search:facet>

return for $in in $var1
        return 
        <search:facet name="facetName" type="xs:string">{
        $in//search:facet-value[not(@name='')]}
        </search:facet>

The only sensible way would be to remove empty elements from your documents, if that is an option.

HTH!
