[Xerte] Re: Converting an object to xml

[Kemp Johnathan]

The problem I was trying to solve was one of having an object in a page,
being able to dump that object as xml data to a file and then being able to
recreate that object from the xml data by reloading the file at a later
date.

So if you started with the object
node[0].att

When it was converted to xml would it matter if it was generated as

<node att="value">
or
<node><att>value</att></node>

since either approach would recreate as an object as

node[0].att

I can understand that if you were starting with the xml you would not know
which format of xml to create when converting back from the object you
created and that therefore you could end up with a different XML structure
to that which you started with. But if you were starting off from the
object, would it not be feasible to have a conversion routine that always
adopted the same approach when converting from an object to the xml data.
Thus making it possible to consistently convert from the object to the xml
and back again? (I know I am talking theoretically here - how you would
achieve it I am not currently sure).

Is there something fundamental about xml that I am failing to grasp here?

Kind regards
