Title: Re: setNodeValue() not working
|
Alberto how do I fix the memory leak from the transcode. BTW forgot to
mention that I'm a newbie just learning this stuff. As for the original problem
I didn't write any code serializing the DOM back to disk. I thought by just
calling setNodeValue that this would save the value passed to disk. Do you have
any sample code or a link on how to do this. This would be much
appreciated...
Thanks
Vince.

Re: setNodeValue() not working
Hi Vince,
from a cursory look to your code, the new values
should update the
FirstName and LastName content (btw, you have a memory
leak by using
XMLString::transcode without releasing the returned
string).
One thing looks strange: you say "the file is not updated", but I
don't see
any code serializing the DOM back to disk. I hope you have
written such
code (otherwise the changes stay in memory): can you post
it?
