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 descri��o 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.
