Andrus,

Your syntax does not work, because the data island is not really a DOM object with a LoadXML method. Try this (remove extra spaces):

< script>
DocHead.innerHTML='< row>< oper>B< /oper>< /row>'
< /script>

Note that to match your original sample, you need to also add the < DocHead> and < /DocHead> at the beginning and end of the above string.

>< xml id=DocHead javaDSOCompatible="true">
>< DocHead>< row>< oper>A< /oper>< /row>< /DocHead>
>< /xml>
>
>< script>
>DocHead.LoadXML( '< row>< oper>B< /oper>< /row>');
>< /script>
