Compare 2 XML docs
I'm building an HTA app that uses XML.
On open of a "project" from my HTA, the program reads in an XML doc to a JavaScript DOM object. I then allow the user to change settings within said DOM. The user can then save thier work via a standard File-Save command that instatiates a xmlDoc.save("{filepath}") call. What I'd like to do is disable the the Save command when no settings have changed. One way I've thought I might be able to do this is to make a clone of the DOM and then compare DOM 1 to DOM 2 to see if they are different. If they are different, the user will be allowed to save. If they are not different, save is disabled. So, is there a way to compare 2 XML DOM objects? Or another way to accomplish what I'm trying to do? {Hope all that jiberish made sense...}

Too simple...
Code:
xmlDoc.load(ProjectDir + "\\sim.xml")
xmlDoc2.load(ProjectDir + "\\sim.xml")
...later...
if (xmlDoc.xml==xmlDoc2.xml){
//No changes to xmlDoc have been made.
}
else{
//Changes to xmlDoc HAVE been made.
}
Please share if you have a better way to accomplish this. For now tho, this is working.
