Reading in XML file, changing elements and saving back to the file

Hi

Reading in XML file, changing elements and saving back to the file,
how can i do that, I want to be able to read an XML file and read out
Elements. for example

<name>Tom</tom>

When I read from a file i want to save the XML document in memory of
the computer and when i am finished flush it back to the file, that
means i want to be able to access the element in memory of the
computer and when i change it will write it back with new changes.

What is the Best way to do that ?
I have tried it wiht xmlReader and xmlWrite, this is not saved in the
computer.

XMLDocument xdoc = new XMLDocument(@"c :\myfile.xml");

// do the changes to the xdoc (in-memory dom)

xdoc.save(@"c:\ myfile.xml");

I think this should work - havent tried it though ;-)

Hi, I've got a simple console app that just reads an XML file into a DataSet then prints out a description of each table in the DataSet, including column names and row values for each column.

The code for my program looks like this:

Hi folks, Suppose I have a large (1 GB) text file which I want to read in reverse. The number of characters I want to read at a time is insignificant. I'm confused as to how best to do it. Upon browsing through this group and other sources on the web, it seems that there are many ways to do it. Some suggest that simply fseek'ing to 8K bytes before the end of file, and going backwards is the way. In this case, am I guaranteed best results...

Hello. I'm writing an application that writes to a file a month, day, year, number of comments, then some strings for the comments.
