I intend to get the node with flash object by parsing the dom tree.
When I use the dom.GetElementsByTagName() to put all the node of the
dom into a node list, I can find a node with nodeName="OBJECT".
<code>
// get the node list with tag = "object"
nsCOMPtr<nsIDOMNodeList> objNodeList;
PRUint32 length = 0;
res = domDocument->GetElementsByTagName(NS_LITERAL_STRING("*"),
getter_AddRefs(objNodeList));
if (NS_FAILED(res))
return NS_ERROR_FAILURE;
else if (objNodeList){
objNodeList->GetLength(&length);
printf("================>node list length:%d\n", length);
}
for (PRUint32 index = 0; index < length; index++) {
nsCOMPtr<nsIDOMNode> childNode;
objNodeList->Item(index, getter_AddRefs(childNode));
if (!childNode)
continue;
nsAutoString nodeName;
childNode->GetNodeName(nodeName);
if
(strcasecmp(NS_LossyConvertUTF16toASCII(nodeName).get(), "OBJECT") ==
0)
printf("%d node name is %s\n", index,
NS_LossyConvertUTF16toASCII(nodeName).get());
}
</code>
But when i want to get the flash node by the tag name "OBJECT", the
length of nodeList is 0.
<code>
res = domDocument->GetElementsByTagName(NS_LITERAL_STRING("OBJECT"),
getter_AddRefs(objNodeList));
</code>
Why can't get the node with nodeName="OBJECT" directly?
Please give me some advices. Thanks in advance.
