Convert XML to String

ForeverBlue

Could someone help or show me the direction how to covert xml into a string?? I tried to save xml into BlOB, then use Instream to readout but I have hard time doing so.
this is what I try to do.

build a xml then save into BLOB. Later on build a second xml then in one of node read out the BLOB as a string, put it as a value of that node.

RECORD.BLOBL.CREATINSTREAM(Instream);
InStream.READ(XmlNode.TEXT); <-- This will give me compile error.

what is the correct way to do it??

Thanks in advance
