We Keep Coding

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;
}
}

How can I select all subnodes of a node, and not all descendats?

I've got the following XML:
<...>
<...>
<tabular>
<time from="2014-05-22T10:00:00" to="2014-05-22T12:00:00" period="1">
<symbol number="3" numberEx="3" var="03d" />
<precipitation value="0" />
<windDirection deg="191.8" code="SSW" />
<windSpeed mps="1.3" />
<temperature unit="celsius" value="16" />
<pressure unit="hPa" value="1010.6" />
</time>
<time from="2014-05-22T10:00:00" to="2014-05-22T12:00:00" period="1">

<precipitation value="0" />
<windDirection deg="191.8" code="SSW" />
<windSpeed mps="1.3" />
<temperature unit="celsius" value="16" />
<pressure unit="hPa" value="1010.6" />
</time>
<time from="2014-05-22T10:00:00" to="2014-05-22T12:00:00" period="1">

<precipitation value="0" />
<windDirection deg="191.8" code="SSW" />
<windSpeed mps="1.3" />
<temperature unit="celsius" value="16" />
<pressure unit="hPa" value="1010.6" />
</time>
I've managed with LINQ to get the tabular list:
var tabular = doc.Root.Descendants("tabular").ToList();
tabular count is now 1. What I want is a list of children of tabular. I've tried the extra descendant:
var tabular = doc.Root.Descendants("tabular").Descendants().ToList();
But that return a list of every descendant of tabular, resulting in a list where time, symbol, precipitation and so on is in the list. How can I get a list where the list contains time nodes of tabular?
I want a list of all time nodes, so I can serialize it to a object and access the values

Use Elements instead of Descendants if you want to get only direct children of tabular
var tabular = doc.Root.Descendants("tabular").Elements().ToList();
UPDATE: Hints for parsing time elements into objects
var times =
from t in xdoc.Descendants("tabular").Elements()
let symbol = t.Element("symbol")
let temperature = t.Element("temperature")
select new
{
From = (DateTime)t.Attribute("from"),
To = (DateTime)t.Attribute("to"),
Period = (int)t.Attribute("period"),
Symbol = new
{
Number = (int)symbol.Attribute("number"),
NumberEx = (int)symbol.Attribute("numberEx"),
Var = (string)symbol.Attribute("var")
},
Precipitation = (int)t.Element("precipitation").Attribute("value"),
WindSpeed = (double)t.Element("windSpeed").Attribute("mps"),
Temperature = new
{
Unit = (string)temperature.Attribute("unit"),
Value = (string)temperature.Attribute("value")
}
};
Output:
[
{
From: "2014-05-22T10:00:00",
To: "2014-05-22T12:00:00",
Period: 1,
Symbol: { Number: 3, NumberEx: 3, Var: "03d" },
Precipitation: 0,
WindSpeed: 1.3,
Temperature: { Unit: "celsius", Value: "16" }
},
// ...
]

XDocument Multiple Elements with same name

In an XML document, I have 3 different elements, all named "time". How do I select the third element in this XML document? (that is named time) Doing this only selects the first one:
xDoc.Root.Element("forecast").Element("time").Element("temperature").Attribute("day").Value
By the way, the XML elements named "Time" have different dates attached to them via attribute "Day", if that is any use.
<time day="2013-12-23">
</time>
<time day="2013-12-24">

Get the value from the third "time" element in your XML:
xDoc.Root.Element("forecast")
.Elements("time")
.Skip(2).First()
.Element("temperature")
.Attribute("day")
.Value;
Or if you prefer to search by the date (more reliable):
xDoc.Root.Element("forecast")
.Elements("time")
.Single(x => x.Attribute("day").Value == "2013-12-25")
.Element("temperature")
.Attribute("day")
.Value;
If there's any chance you could be searching for a date that exists multiple times in the file, you'll need First as Single blows up if there's more than a single record.
If there's any chance of searching for a date that doesn't exist in your XML at all, look into SingleOrDefault or FirstOrDefault, as those return null if the record doesn't exist instead of throwing an exception. If that's the case, you'll need to split the above query into two parts, testing for null before trying to get the day's temperature.

Using your XML Sample, this is what you can do to obtain only the third element.
IEnumerable<XElement> times = (
from item in xDoc.Root.Element("forecast").Elements("time")
select item).Skip(2).Take(1);
foreach (XElement el in times)
Console.WriteLine(el);
Hope this helps

How to Read XElement contents containing Sharepoint List Structure?

I want to get above values following from XML.
<CHOICES>
<CHOICE>Articles</CHOICE>
<CHOICE>Websites</CHOICE>
<CHOICE>Books</CHOICE>
</CHOICES>

Provided you fix your XML, this does what you want:
var choices = (from n in xml.Descendants()
where n.Name.LocalName == "CHOICES"
select new
{
CHOICES = n.Elements().Select(x => x.Value).ToList()
}).ToList();
Will give you a list of the anonymous type CHOICES elements that contain your CHOICE element values. Example output:
Edit
See comments:
var choices = (from n in xml.Descendants()
where n.Name.LocalName == "CHOICE"
select n.Value).ToList();
This will return a list of the following string values:
Articles
Websites
Books
0;#Approved
1;#Rejected
2;#Pending
3;#Draft
4;#Scheduled

Hide ComboBox and/or DateField based on Radio Button selection in Ext.net codebehind

I am trying to hide a ComboBox and/or DateFields based on my selected radio button in the codebehind in Ext.net

</ext:Button>
</Items>
</ext:Container>
</Items>
</ext:Container>
</Items>
</ext:Panel>
</Items>
here is the code behind using C#:
[DirectMethod]
public void DateSelection()
{
if (ChooseSpan.CheckedItems[0].ID == "RadioAll")
{
MonthComboBox.Visible = false;
StartDateField.Visible = false;
EndDateField.Visible = false;
}
if (ChooseSpan.CheckedItems[0].ID == "RadioMonth")
{
MonthComboBox.Visible = true;
MonthComboBox.Show();
StartDateField.Visible = false;
EndDateField.Visible = false;
}
if (ChooseSpan.CheckedItems[0].ID == "RadioDate")
{
MonthComboBox.Visible = false;
StartDateField.Visible = true;
StartDateField.Show();
EndDateField.Visible = true;
EndDateField.Show();
}
}
Do i need a listener in the RadioGroup to accept these selections? how do i get the codebehind to respond to my selection, and tell it to hide or not?

Please listen the RadioGroup's Change event to call a server method.
To hide/show the components please use the Hidden property instead of the Visible one. Here is a bit of details about the difference.
As well you can use the Show and Hide methods.
