Question on Xpath Count?

Hello all,

On my Xform I have the following construction:

<xforms:output value="count(.[/a/b[@attr='something']//c = 'true'])"/>

And in my instance document, I have:

<ser:ciz xmlns="http://www.workflow4people.org/services" xmlns:ser="http://www.workflow4people.org/services">
                       
                        <a>
                            <b attr="something">
                                <c xsi:type="xs:boolean">false</c>

                                <d>Me</d>
                             </b>
                           
                             <b attr="something">
                                <c xsi:type="xs:boolean">false</c>
                                <d>You</d>
                             </b>        
                        </a>

This count always returns 1 or zero. If no c-elements are set to true, a 0 is returned. If there's one ore more set to true, a 1 is returned, always.

What am I doing wrong?

 Hello Jeremy,

I'm trying the nr. of c-elements set to true.

Is the text function the thing I should be using? As the field is typed as a boolean...

Best, Robin

What exactly are you trying to count?  If you're looking to count the
element "<a>" then your syntax appears to be working as desired.  If you
wanting to count the number of <b> elements with a <c> element of true,
then the syntax would be:

count(./a/b[@attr='something' and c='true'])

If you're trying to count the number of <c> elements that are true, you
could use this:

count(./a/b[@attr='something']//c[text()='true'])
