How to write a xml using a list

Pablo Costa

[Walk trough list and write XML]
Hi everyone.
I'm kinda stuck on a part of my code.
I've a list on wich every position receives an xmldata (custom class). It contains three positions (colorname, colorvalue and xml_filename).

On my method to write xml , i'm trying to setup a foreach statement to write an XML for each xml_filename
i.e: Positions from 0 to 4 have a xml_filename called bla.ppf , positions 5 to 9 have a xml_filename called ble.ppf .

How could i walk trough my list , write the XML based on each xml_filename field of the list ?

I've readed about linq methods for converting the list to xml directly but i know nothing about linq (c# newbie)

Basically: each list position has tree elements from my custom class. The element xml_filename determines which file the field belongs and its attributes. The foreach loop should be something like (foreach item in xmllist) , write one xml using fields where xml_filename is equal (from positions 0 to 5 , example). From positions 6 to 9 another file (field xml_filename will change) and so goes on.

I've posted the whole code on pastebin (big to post here). Thanks !

On main method you can call like this:

var grouped = XList.FullList.GroupBy(s => s.xml_filename).Select(grp => new { grp.Key });
foreach (var filename in grouped)
{
//will take List and variables as a parameter..
writexml(XList.FullList.Where(i => i.xml_filename == filename.Key).ToList(), v);
}

Check a new post i made - i changed the code and made things easier.
Now i'm dealing with only one thing.

Didn't worked as expected. writetoxml takes another argument , and if i instantiate a new instance of it inside this method i won't be able to access the value of the variables on it.

//first group by file names..
var grouped = XMLList.FullList.GroupBy(s => s.xml_filename).Select(grp => new {grp.Key});
// for each file name send its xmldata
foreach (var filename in grouped)
{
//takes List as a parameter
WriteToXml(XMLList.FullList.Where(i => i.xml_filename == filename.Key).ToList());

}

This would walk trough each item. I need to group by xml_filename to write the XML for this filename. Lets say positions 0 to 5 have a xml_filename called file1 , every position with its specific attributes. I need to write'em to file1 , and so goes on.

I guess like this :
foreach (xmldata item in XMLList.FullList)
{

}
