[jdev] .Net XML Dom Stuff

[Jonathan Dickinson]

Hi All,

For those of you who are interested, I have found a work-around for the classical DOM issues and streams in .Net (large DOM after a busy client). The solution is obvious if you think about it and I have no idea why I didn't come up with it before.

Simply delete the elements from the DOM as you no longer need them! Here is some code demonstrating the concept:

void IXmlNotificationTarget.XmlElementStarted(XmlElemen t element)
{
depth++;

object o = Deserialize(element);

// Root.
if (depth == 1)
{
if (o != null)
target.StanzaOpened(o, depth);
}
// Stanza.
else if (depth == 2)
{
if (o != null)
target.StanzaOpened(o, depth);
}
}

void IXmlNotificationTarget.XmlElementEnded(XmlElement element)
{
object o = Deserialize(element);

// Root.
if (depth == 1)
{
if (o != null)
target.StanzaClosed(o, depth);
}
// Stanza.
else if (depth == 2)
{
if (o != null)
target.StanzaClosed(o, depth);

// Remove self.
element.ParentNode.RemoveChild(element);
// Completely destroy.
element.RemoveAll();
}

depth--;
}

HTH
