Subject Re: serialise to memory, parse back in from memory
Date Mon, 21 Jul 2008 08:53:53 GMT
Hi Alberto,

Thanks for the quick reply.

So to write out to memory I used
XMLFormatTarget *myFormTarget;
myFormTarget = new MemBufFormatTarget();
theSerializer->writeNode(myFormTarget, *doc);

This seems to have worked, problem is now reading back in.

You say to read in I use MemBufInputSource object, but I am confused as to
how I get the MemBufInputSource  to point to the MemBufFormatTarget
(myFormTarget) which contains the data I wrote earlier.
Are they interchangable?

To clarify, I have written the data to myFormTarget, of type
now I want to read it back in using myinput of type MemBufInputSource
but how can I get myinput to source the input from myFormTarget?
