XercesDocumentBridge::importNode

[Andrei Smirnov <as...@hotjobs.com>]

hi

method in subj is not implemented. i don't know what the plan
about it but look at patch below. the major problem was that
mapping of imported xalan node to dom node was not working.
my case was someone have read another xml file with
XercesParserLiaison::parseXML.

after some looking i got idea that BridgeWalker should
create mapping when XercesDocumentBridge ctor works. that goes to
method below

void
XercesDocumentBridge::BuildBridgeTreeWalker::startNode(const DOM_Node&
node)
{
	XalanNode* const	theBridgeNode =
m_document->createBridgeNode(node, m_currentIndex, true);
                                                   ^^^^
                                              was false


after this fix the implementation of XercesDocumentBridge::importNode
have started to work for my case. only thing one need to remember that
once imported node has been added to destination tree last one
should rebuild the bridge.

andrei
