为什么,在做之后appendChild
,我无法读取下一个节点?
(newChildList->get_item(count,&pNewChild))
appendChild
API 无法正常工作。在我放了这条线之后,我无法获得下一个get_item()
循环。它返回pNewChild
是NULL
. 为什么会这样?
IXMLDOMNode *pNewChild=NULL,*outNewChild;
IXMLDOMNodeList *newChildList=NULL;
BSTR newName;
long len=0;
HRESULT hr=S_OK;
//aggregate attribute
//CHK_HR(aggregateAttribute(pNodeNew,pXMLDomSrc,pXMLDomNew));
//read the list of child
CHK_HR(pNodeNew->get_childNodes(&newChildList));
CHK_HR(newChildList->get_length(&len));
//go over all the children
for(long count=0;count<len;count++)
{
hr =newChildList->get_item(count,&pNewChild);
CHK_HR(pNewChild->get_nodeName(&newName));
USES_CONVERSION;
string temp= W2T(newName);
temp = temp.substr(temp.find_first_of("/:")+1);
if (!temp.compare("tuple"))
{
//CHK_HR(aggregateTuple(pXMLDomSrc,pNewChild));
}
else
{
CHK_HR(pXMLElement->appendChild(pNewChild,&outNewChild));
}
SAFE_RELEASE(pNewChild);
//SysFreeString(newName);
}
CleanUp:
//SAFE_RELEASE(newChildList);
SAFE_RELEASE(pNewChild);
return hr;
