Hi,
Thanks for this important piece of information. I
believe all the samples that I've seen so far use
someCall(XMLString::transcode(...))
What about the "getDOMImplementation(...)" function?
Does it dynamically allocate memory in the buffer?
(Sorry for my ignorance -- I tried looking at the API
for this, but couldn't find the info that I needed.
I'm just trying to ensure that I don't end up with
memory leaks in my application.)
Thanks,
Monica
