how to re-use the parsed document

[林 子芯 <mi...@hotmail.com>]

hi,
prehaps it is a trival task for most of you guys, but i couldn't get it 
right, i was wondering whether it is possible to save the parsed document 
and allow it to be use whenever it is needed. at present i have an xml 
document that is needed for different purposes, so instead of re-parsing 
the document each time for specify purposes, can i stored the parsed 
document in a variable and call such variable whenever it is needed.  if it 
is possible can somebody suggest how it could be done? 

Many thanks
Regards
Kit

If you are using DOM this is a trivial task.
Just store the DOMDocument object and make a clone of it everytime you need
to use it.
Cloning the document is performed like this.

Create a new DOMDocument with the same namespace, publicid, systemid and
DocType as the original.
Deep import the root node from the original document into the new document
and thereby get a new node.
Add that node to the new document as root.
Now you have a copy. I might have forgotten some step or problem but you'll
probably work it out by yourself.
