http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24693 DOMNode::getTextContent() corrupts heap [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |INVALID ------- Additional Comments From [EMAIL PROTECTED] 2003-11-14 00:47 ------- There are a number of problems with this code: 1. There actually is no problem with having Xerces-C objects allocated in the same scope as the call to XMLPlatformUtils::Initialize(), but it will become a problem if you start calling XMLPlatformUtils::Terminate(). You should scope these objects properly: XMLPlatformUtils::Initialize() { XercesDOMParser parser; ... } XMLPlatformUtils::Terminate(); 2. There is no problem with calling getNodeName() on any type of node, it's just that the name you get back may not be very interesting. For example, you'll get "#text" for text nodes. 3. You are casting using C-style casts, which are an invitation to disaster. 4. You are casting nodes to the wrong types, because you don't understand basic concepts of XML. You are assuming the first child of the element "Object1234567890" is an "Obj" element node, but that's not the case. The first child is actually a text node that represents the whitespace between the two element nodes. When you cast that DOMText node to a DOMElement node, you are casting to the wrong type, so disaster ensues. Here's a very brief patch the fixes the problem, although I don't recommend it for production, because it really relies to0 much on the structure of the input document: if (XMLString::compareIString(name, L"Object1234567890") == 0) { pChild = pNode->getFirstChild(); pChild = pChild->getNextSibling(); // Added to fix the bug... Adding this lines of code fixes the problem and the code runs without problems. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
