How to free memory after a XMLString::transcode

[Marian Roselló Bennassar]

Hi,
 
I have a memory leak problem in my program. The memory leak seems to be caused 
by the XMLString::transcode, after which I fail to release memory correctly. 
This is how I use it:
 
    DOMNode* sysChild;
    char* sysChildName;
    String   nodeName;
     ...
    
     for(int i=0; i<sysElemChildren->getLength(); i++)
     {
            sysChild = sysElemChildren->item(i);
            sysChildName = XMLString::transcode(sysChild->getNodeName());
            nodeName = String(sysChildName);
            ...
    }
 
    XMLString::release(&sysChildName);
 
 
As you can guess from the code I need to retrieve the name of the node as a 
String. I thought that with  the release memory would be released/freed, but it 
does not seem to be the case.
Has any of you encounter the same problem? Could you please tell me how could I 
obtain the node name as a String and release the memory to avoid the leak? 
 
I would really appreciate any help, I have to parse a very big XML file, so 
little problems like this one become huge!!!
 
Thank you very much in advance.
 
Cheers,
Marian.
