Append/Replace XML section? [resolved]

How can I append or replace a single section within my XML file?

Currently, I am having to save the entire XML file when I make changes to my data. But I would like to be able to reduce the time, by only saving 1 section of the XML file.

I would like to be able to save info to the user settings, without saving the entire user and data items, etc.

PHP Code:

---

...
<user>
   <settings .... />
</user>
<data>
   <item ... >
       ....
   </item>
   ...
</data>
... 


---

Reference: (This is how I am reading/writing XML)
Read XML from a file
Write XML to a file

thanks,

Any ideas if this is even possible?

I don't think it is, sorry. I have never seen anything that can save or load only part of a file. You can break the xml tables up into seperate files and that would work.

From quick glance at this page , it says you can read XML Nodes . I don't know if it's right .

If I were you , I would store all these info in database file !!
I hope that helps !

Yeah you can change it via nodes or read or write nodes but you will still need to load the xml file into an xmldocument first. :(

Thanks for the help. I believe that the node reading (in the web page) still requires the app to loop through the document (I am bascially doing the same commands when I read/write the XML file.) I don't think it is possible either, but it seems like something that should .NET should be able to do.

How are you reading and writing the document now?

Read this article here.

Are you talking about Web XML Files ??:rolleyes:

Whats the difference between a web xml file and any other xml file? They are all the same.

Yeah , I guess so :D . So he can use text file to append/replace . Is it easier ?:rolleyes:

I guess thats just a matter of opinion. I think using either a Dataset or an XMlDocument objects is the best. I don't like using just text or the XMLTextWriter/Reader that seems like too much work.

Yes Ed , I agree with you .;)

The XMLdocument looks much better, I just haven't used it before. Looks like that would be better for me to start using instead of the XMLTextReader/Writer.

Thanks all.

Update: I just changed all my read/write to XMLdocument and it worked great. I was able to just edit a certain section or even a certain element, etc.
