How to handle xml Attributes?

Hallo,

I am new at Livecycle and I have some trouble to figure out how to read/bind XML attributes in LiveCycle Designer.

If I drag & drop elements (#data from Data View) they appear without problems. But if I drag&drop an attribute (@attributename) they always show up empty at the PDF.

For example I have a XML File that Looks like that:

<product>

....

         <price>

            <oldprice visible="true">

                <priceA visible="false">1.350,00</priceA>

                <priceB visible="true">1.350,00</priceB>

                <priceC visible="true">20,00</priceC>

                <priceD visible="false">0,00</priceD>

            </oldprice>

            <newprice visible="true">

                <priceA visible="false">1.350,00</priceA>

                <priceB visible="true">1.350,00</priceB>

                <priceC visible="true">20,00</priceC>

                <priceD visible="false">0,00</priceD>

            </sonderpreise>

          </price>

...

</product>

I tried to bind it like that: price.oldprice.(visible.value=="true").priceA but it does not work.

I can´t really find some good informations about handling XML Attribute in LiveCycle. Can someone please help me or tell me where to find more Information about that subject.

Thank you!!!
