Hi,

I have a long XML document like this :

<cities>
  <city>
    <name>Paris</name>
    <zip>75000</zip>
    <alt_names>
      <name>paris</name>
    </alt_names>
  </city>
  <city>
    <name>Cesson-Sévigné</name>
    <zip>35510</zip>
    <alt_names>
      <name>cesson-sevigne</name>
    </alt_names>
  </city>
</cities>

My XQuery is supposed to return the cities whose name begin with a few letters contained in "$search". So I use this :

let $search := request:get-parameter("search","")

return
    <cities>
        {
        for $city in collection("cities")//city[starts-with(alt_names/name,$search)]
        return
          <city>
                       {$city/name}
                       {$city/zip}
          </city>
        }
    </cities>

But there is a problem with the [starts-with(alt_names/name,$search)] part. It seems that I cannot use the same tag name ("name") both in "city" and in "alt_names". The error is :

[XPTY0004] No sequence (element name { ... }, element name { ... }) allowed.

1) Is this a bug?

2) What is the equivalent in BaseX to request:get-parameter, which works in "eXist db" and affects the GET parameter (here "search") to the $search variable?

Thank you for your help,

Regards,
Grégoire

PS : I corrected the variable name which is, obviously "$search" and not "$cityname" (please ignore the previous message).
