Optional elements in XML transformation

[Former Member]

Hi,

I call a transformation ( defined in STRANS ) that has as source a XML document and as destination several Abap variables.

I have a dump when transforming the XML, because some elements sometime do not exist in XML to transform.

For example, if the element <fax tt:value-ref="$REF.C250"/> of the bellow example does not exist in a XML, how can i preview it ? How do I don't have problem if tag <fax> does not exist

I know there's a property minOccurs="0", I've seen in several forums but I don't know how to adapt it to the bellow example. Can anyone help me solve this problem.

Thanks,

Paulo Sousa

Can't see your example - are you using XSLT or ABAP ST? For ABAP ST, you can make a node in the template conditional as follows:

        <tt:cond frq="?">
          <Location>
            <tt:value ref="LOCATION"/>
          </Location>
        </tt:cond>
