Why must you consider your log a well-formed XML document? If you instead treat it as a well-formed XML external parsed entity, then you are freed of the append problem, while being fully XML compliant. And, of course, you already hit upon this solution yourself, by enclosing your log in a simple wrapper to create an XML document for processing. Despite the recent controversy about EPEs, most XML tools should support them, and so you shouldn't even be too constrained in your XML tool-set. But again, I don't see a problem with XML here. -- Uche Ogbuji FourThought LLC, IT Consultants uche.ogbuji@f...
