[Expat-discuss] Using XML_GetBuffer/XML_ParseBuffer

[James Whetstone]

Another question along the same lines is whether or not I even need to worry 
about overwriting left over data in the XML Buffer.  I assumed there would 
sometimes be some left over data of a XML fragment in the buffer, but maybe 
that isn't the case.
