QUERY REFERENCES IN PML

Hi

How can I have something like HREF of a branch in form of like "TEE 1 OF /10"-AA-100-501800" in a PML variable, instead of REF of that TEE.

The big picture is I want to copy whole SITE into another and changing the names and references respectively. For this I thought that it is easier to change for example "TEE 1 OF /10"-AA-100-501800" to "TEE 1 OF /10"-AA-200-501800" . which is from unit "100" to unit "200".

Thanks in advance
