[xml] Error handling

["Gijun Lee" <kengijunlee hotmail com>]

Hello,

I am using LibXML for the system I am working on. It is a well written 
library and easy-to-use. I used libxml heavily in my source code. Only thing 
I am left with is regarding error handling. Seems like libxml prints all 
errors into stderr. For example, if a XML document has invalid entries, it 
catches the error and prints into stderr.  But I want to capture that error 
message and send the error message to the user via email.

I want to know how I can capture the error message and put into a buffer. 
Any information would be greatly appreciated. Of couse, any example would be 
good, too.


Thanks.
