Releasing DOMNodes not releasing all of memory

[Mouawad, Tony]

Hello,   We're currently faced with a challenge where when we create DOMNodes, use them and then release them, our application memory keeps growing with each DOMNode created and released.  In order to free up the memory consumed with by several iterations of creating and releasing DOMNodes, we have to actually release the document associated with the nodes to regain that memory.  This is sensible, except for the fact that we designed ourselves into a situation where we cannot release the associated DOMDocument until the application is terminated.  This is partly because of how we are using a XML C++ code generator to bind generic C++ objects to XML data.   My current understanding with versions of Xerces C++ including the most current version is that creating and releasing DOMNodes in a DOMDocument consumes memory and will keep consuming memory until the document is released.  Is this true?   Can someone recommend a way of releasing the consumed memory without actually releasing the document?    If this question is not relevant to this particular mail group, can someone point me in the right direction?   Thank you, Tony
