Well, I'm not happy with the answer. It is working as designed, but this does imply that the design is somewhat flawed. The xpath support was only specified to work with instances of SDO_DataObject. But $record->logicalPort is not an SDO_DataObject, it is an instance of SDO_List. The problem is apparent if you try to access a list element using an xpath. For example $do = $record->logicalPort['portId=24']; results in the oh-so-explanatory message: PHP Fatal error: main(): internal error (747) - invalid dimension type 6 in <source> on line <nn> In other words, you are using a String (type==6) as an index into a list, but only Integers are valid. There's clearly a check missing somewhere, because when you do your unset, it just silently fails and doesn't present an error message. I'm not hopeful that Tuscany would want to add the function to access a list element using xpath, though I could ask. In the PHP implementation, we could at least fix both the baffling error message and the failure to output an error message when you attempt to unset a list element using xpath, though. As discussed, your best bet for now is to iterate through the list to find the index of the element you want to remove. Then unset it using the index as a numeric index.
