Memory Manager

Hi All,

I try understanding Memory Manager, see this code:

-----------------------------------------------

std::auto_ptr<XercesDOMParser> pParser(new XercesDOMParser());

try {

pParser->parse(m_strSelectedItemPathName);

}

catch (...) {

return CString("Erro em obter a descrição do projeto.");

}

xercesc_2_6::DOMDocument* pDoc = pParser->getDocument();

DOMElement* pRoot = pDoc->getDocumentElement();

DOMNodeList* pNodeList = pRoot->getElementsByTagName(X("projectdescription"));

CString strMsg;

for ( int i = 0 ; i <= (int)pNodeList->getLength() ; i++ )

{

DOMNode* pNode = pNodeList->item(i);

if(pNode != NULL)

{

strMsg = pNode->getTextContent();

}

-----------------------------------------------

My doubt is, I don’t need release: DOMNode* pNode, DOMElement* pRoot and DOMDocument* pDoc.

When I release XercesDOMParser* pParser all others is released together?

How I know when I need release?

Thanks for help.
