Using C#, how can we pull attribute values from an XML Schema file and output that onto a CSV file?

I am trying to pull the attribute values for each of the element, that is in this XMl Schema file(XML below). I want the attribute values for the following: type, label, CompTypes, readonly, hidden, and required.
For example, here is one of the elements in the XML file:
<element type="xpowercomponent_FeaturedTiles" UID="40204fc9b5424b349e03134d777d29bc" label="Featured Tiles" readonly="false" hidden="false" default="" required="false" Component="" CompTypes="ThemedTileSetComponent;ThemedTileSetElectedComponent;" AutoEmbed="" WrappedUp="" AllowWrappingChange="" />
The expected result for this element should be:
xpowercomponent_FeaturedTiles, Featured Tiles, ThemedTileSetComponent,
ThemedTileSetElectedComponent, readonly="false", hidden="false",
required="false"
I have started a C# app to get this information, however it is not getting all the information properly. Could you please take a look at the code, and see how this can be fixed or improved? Is there a better way of approaching this, maybe LINQ? The ultimate goal is to then output these attribute values/data in a CSV file.

you can use System.Xml.Linq to get all the elements and the required attributes as below
XDocument document = XDocument.Load(#"D:\New Text Document.xml");
var eleCollection = document.Elements("element");
foreach (var element in eleCollection)
{
var type = element.Attribute("Type").Value;
}

This is easiest way one can use for loops on nodes to get the information in each node.
use node.ChildNodes property to get the chilenodes.
XmlDocument doc = new XmlDocument();
doc.Load("filepath");
//Here Path could be- "//ElementType" ---> this will give all nodes with name ElementType
XmlNodeList nodes= doc.SelectNodes("//give path of nodes you want attributes for");
foreach (XmlNode node in nodes)
{
//Assuming you want information of element tags
foreach (XmlNode child in node.ChildNodes)
{
string name= node.Attributes["type"].Value;
string name= node.Attributes["label"].Value;
}
}

Loop through each file in directory and write output to text

I have around 15,000 XML files in a folder, an example of a XML filename is; 000010000.img.xml
Each XML file contains specific information I need in a single text file.
Each XML file has the exact same structure aside from the information presented.
Here is what I want to focus in on (within the XML file)
<imgdir name="000010000.img">
<imgdir name="info">
<int name="version" value="10" />
<int name="cloud" value="0" />
<int name="town" value="0" />

A batch file does not work; as you can see in my other thread: Batch script not working?
I need a C# application to open each XML file, grab specific information (that I will specify below), write that information into a single text file, and rinse and repeat till every XML file has been read.
Using the XML file snippet/actual XML file information posted above, here is how I need the text file text structure to be;
[10000]
total=4
sp 0 -389 183 999999999
sp 0 -416 185 999999999
sp 0 -450 183 999999999
out00 2 1080 541 20000
I just cannot wrap my head around on how to do this in a c# console application.
I am asking for help, anything is appreciated!

string[] files = Directory.GetFiles(#"SomeWhere");
List<string> result = new List<string>();
foreach (string file in files)
{
string[] lines = File.ReadAllLines(file);
// Grab information from the lines and store it in result
// by using result.Add(...) or result.AddRange(...)
}
File.WriteAllLines(#"AlsoSomewhere", result);

Here is a quick and dirty program I wrote up. I had to add a root to your XML file for it to play nice-nice with the program. I hope this helps!
Code:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Xml.Linq;
namespace ConsoleApp5 {
public class Program {
public static void Main(string[] args) {
string test = getValuesOneFile("xmltest.xml");
Console.WriteLine(test);
Console.ReadLine();
}
public static string getValuesOneFile(string fileName) {
string finalString = "";
XElement xmlDocument = XElement.Load((fileName));
XElement infoImgDir = GetImgDir(xmlDocument, "info");
finalString += "[" + GetInt(infoImgDir, "returnMap") + "]\n";
finalString += "total=" + GetChildrenCount(GetImgDir(xmlDocument,"portal")) + "\n";
IEnumerable<XElement> portals = GetImgDir(xmlDocument, "portal").Elements();
foreach (XElement currentPortal in portals) {
finalString += GetString(currentPortal, "pn") + " ";

finalString += GetInt(currentPortal, "x") + " ";
finalString += GetInt(currentPortal, "y") + " ";
finalString += GetInt(currentPortal, "tm") + "\n";
}
return finalString;
}
public static XElement GetImgDir(XElement file, string imgDirName) {

}
public static int GetInt(XElement data, string attribName) {

How to draw multi-series column chart in FusionCharts

I am developing a web application using asp.net c# and drawing graphs using FusionCharts. I need to draw a multi-series column chart for which i tries the following code, but in vain
<div id="chartContainer"></div>
<script type="text/javascript">
var myChart = new FusionCharts("Column3D", "myChartId", "400", "300");
myChart.setXMLUrl("Data8.xml");
myChart.render("chartContainer");
</script>
Data8.xml
----------
<chart caption='Sales by Product' numberPrefix='$' formatNumberScale='1' rotateValues='1' placeValuesInside='1' decimals='0' ><categories>
<category label='Product A' />
<category label='Product B' />
<category label='Product C' />
<category label='Product D' />
<category label='Product E' />
<category label='Product F' />
</categories><dataset seriesName='Current Year'>
<set value='567500' />
<set value='815300' />

<set value='456300' />
<set value='754500' />
<set value='437600' />
</dataset></chart>
Please help me to do this...

Try to modify:
var myChart = new FusionCharts("Column3D", "myChartId", "400", "300");
With:
var myChart = new FusionCharts("MSColumn3D", "myChartId", "400", "300");
Column3D is for a single serie, and MSColumn3D is for Multi-series.

You have namespaced elements in the document so you need to include them in your queries.
XNamespace itemNs = "urn:schema:Microsoft.Rtc.Management.ScopeFramework.2008";
XNamespace assignmentNs = "urn:schema:Microsoft.Rtc.Management.Settings.ServiceAssignment.2008";
var query =
from item in doc.Descendants(itemNs + "Item")
from assignment in item.Descendants(assignmentNs + "ServiceAssignment")
select (long)assignment.Attribute("TagId");

string xmlString =

var doc = XDocument.Parse(xmlString);
var TagIds = doc.Descendants()
.Elements()
.Where(e =>
e.HasAttributes &&
e.Name.LocalName.Equals("ServiceAssignment") &&
e.Attribute("TagId") != null)
.Select(e => e.Attribute("TagId").Value);

Your XML contains namespaces, so you can't just compare the full name.
If you don't care about the namespaces, you can use XName.LocalName:
var result = from element in doc.Root.Descendants()
where element.Name.LocalName == "ServiceAssignment"
select (int)element.Attribute("TagId");

You can try with this code
var result = from item in XElement.Load("YourFile.xml").Root.Elements("ServiceAssignment")
where item.Attribute("TagId") == value
select item ;

How to add "BDC Wildcard Filter" to the ReadList method

Good Morning :)
Situtation: In SP2010, I've a customer list with a external data field. In the solution I have a BDC Model with an entity which contains a "ReadItem" and a "ReadList" method. When I deploy my feature and set the object permissions, I can read the Item without troubles. Now i have to search an item. I follow this instructions to create a Filter: http://msdn.microsoft.com/en-us/library/ee471425.aspx but it doesn't work, because I have always the same value in my parameter ("**") ..
Question:
1. How can I assign the search input to the parameter?
2. Is something other wrong?
Code
public IEnumerable<Oppertunity> ReadList(String inputParameter)
{
using (CRMDataClassesDataContext db = new CRMDataClassesDataContext("server=xxx;database=xxx; uid=xxx ;pwd=xxx"))
{
List<Oppertunity> oppertunities = new List<Oppertunity>();
var q = from c in db.Opportunities
where c.Name.Contains(inputParameter)
orderby c.Name ascending
select new Oppertunity
{
OppertunityId = c.OpportunityId,
Name = c.Name,
};
foreach (var o in q)
{
Oppertunity oppertunity = new Oppertunity();
oppertunity.OppertunityId = o.OppertunityId;
oppertunity.Name = o.Name;
oppertunities.Add(oppertunity);
}
}
return oppertunities;
}
The BDC part looks like the instructions of msdn:
