Possible to detect changes to an XmlDocument object?

If I instantiate an XmlDocument object, the load a file through the Load
method, is there a way, later on in execution, to easily determine if the
XmlDocument object has changed from the original version loaded?

I'd like to be able to check a condition to see if the document in memory
has been editted (i.e., nodes added, attributes changed, etc.) so that my
user can decide whether or not to commit changes to the disk file before
moving to another file.

Will I have to resort to re-loading the file, and comparing OuterXml
properties?

You can set up event handlers on the document so that your code is
notified about changes, see

Hi, I've been buried in xsl and xslt articles for several days now, and am still unsure as to what I need to do... Basically, my vb.net app loads up an XML file from an external source (Input.xml). When the user is setting up the source, they can make changes to it to specify which columns to include for use in my app, they can rename columns, they can mark a column as being of a known datatype (my own custom datatypes, e.g. a Tree). ...

I'm trying to send and receive XmlDocument objects using the System.Messaging.dll functions. The code I've written follows, as best I can tell, the methodology used in the sample code for the XmlMessageFormatter class. But it isn't working -- specifically, receiving isn't working. What am I doing wrong here? I begin by creating a MessageQueue object and setting up its XmlMessageFormatter to handle XmlDocument objects: System.Type...

Hello, I have profiled my code, and the current performance bottleneck is this routine. It gets called 7400 times to do some intensive calculations when a user uses the feature. The xmlText parameter will be used to pass in a xml document text stored in db, the text contents (about 200 of these guys total) are stored in a cached static variable. My web app must be thread-safe, so I cannot create and cache 200 XmlDocument objects...

Hi, I'm trying to select specific nodes from a XmlDocument filled with a serialized object and to insert these nodes into another XmlDocument. The object is well serialized (see below).
