Hi,
I am currently using the XPathWrapper example as a model for my application. I've created a pointer to an object from the XalanSourceTreeParserLiaison class and allocated memory using "new".
m_pLiaison = new XalanSourceTreeParserLiaison(*m_pDOMSupport);
However, whenever I attempt to delete the object (m_pLiaison) I get a "Unhandled exception in XalanSourceTreeD.DLL: Access Violation" error.
If I don't do a delete, then I get memory leaks in areas where the element and comment nodes are created in the XalanSourceTreeContentHandler. It appears that XalanSourceTreeDocument::createElementNode(...) and XalanSourceTreeDocument::createCommentNode(...) do not clean up the memory once the objects are created and added to the Xalan Source Tree.
I need to avoid the Access Violation error and still prevent memory leaks. Please help.
Below is a partial copy of the stack at the point at which the leaks appear:
