Hi all,
I've modified DocumentImpl::importNode() to update the importing document's
map fNodeIDMap when importing nodes with ID attributes.
The only problem occurs if the importing document's DTD doesn't define the
imported attribute as an ID. Is there any way to check against that?
Here's the code:
NodeImpl *DocumentImpl::importNode(NodeImpl *source, bool deep)
{
// SNIPPETYSNIP
case DOM_Node::ATTRIBUTE_NODE :
{
if (source->getLocalName() == null)
newnode = createAttribute(source->getNodeName());
else
newnode = createAttributeNS(source->getNamespaceURI(),
source->getNodeName());
// if source is an AttrImpl from this very same implementation
// avoid creating the child nodes if possible
// if (source instanceof AttrImpl) {
AttrImpl *attr = (AttrImpl *) source;
if (attr->hasStringValue()) {
AttrImpl *newattr = (AttrImpl *) newnode;
newattr->setValue(attr->getValue());
deep = false;
}
else {
deep = true;
}
//
// start importing ID
// The imported attribute is an ID. Add it to the hashtable of
IDs
// that is constructed for use by GetElementByID().
//
AttrImpl *newattr = (AttrImpl *) newnode;
if (attr->isIdAttr())
{
newattr->isIdAttr(true);
if (fNodeIDMap == 0)
fNodeIDMap = new NodeIDMap(500);
fNodeIDMap->add(newattr);
}
//
// end importing ID
//
// }
// else {
// // Kids carry value
// deep = true;
// }
}
break;
// SNIPPETYSNIP
