I need a help to parse the below XML, What I wanted to do is the count of the entry id, below XML has 5 for entry id's. So What code should I write on C# to get the count from this XML? Thanks in advance
<entry_list version="1.0">
<entry id="cipher[1]">...</entry>
<entry id="cipher[2]">...</entry>
<entry id="cypher">...</entry>
<entry id="substitution cipher">...</entry>
<entry id="transposition cipher">...</entry>
</entry_list>

Try this:
var xdoc = XDocument.Load(#"FileToLoad.xml");
var count = xdoc.Descendants("entry").Count(); // 5

I want to know if it is possible to extract and element from a XML in the following fashion. I have tried multiple options such as LinqToXMl and XPath.
<Paper>
<HeaderText>
StackOverFlow
</HeaderText>
</Paper>
For the above XML, if my input is "HeaderText" (the element to be retrieved).
How can I do that without accessing the root element?
Thank You!

XPath has a double-slash which looks anywhere:
//HeaderText/text()
That will return Stack Overflow.

I used the following code to get this working.
XmlDocument document = new XmlDocument();
document.LoadXml(requestXmlString);
XmlNodeList nodes = document.DocumentElement.SelectNodes("//HeaderText");

I am using XML Auto in my SQL Server to query data out. I want to know how best to parse through the data that it provides.
My end goal is to provide a list of items with their values, but I don't know how many columns or what the names of the columns will be until at least the data is pulled form SQL at runtime.
Here is a sample XML
<animals>
<animal name="Pig">
<meat>
<name>Prosciutto</name>
</meat>
<meat>
<name>Speck</name>
</meat>
</animal>
<animal name="Cow">
<meat>
<name>Clod</name>
</meat>
<meat>
<name>Brisket</name>
</meat>
<meat>
<name>Tri-tip</name>
</meat>
</animal>
<animal name="Chicken">
<meat>
<name>Drumstick</name>
</meat>
</animal>
</animals>
How can I show this in a list, and perform Linq2SQL (or Linq2XML)?

To select a list
var q = from x in doc.Descendants()
select x.Value;
to select specific nodes, e.g. animals, do doc.Descendants("animal")
to select specific value, e.g. name of an animal do select x.Attribute("name").Value

I have a document (xml) where each line has a format like this
<Field ID="{475c2610-c157-4b91-9e2d-6855031b3538}" Name="FullName" DisplayName="Full name" Type="Text" SourceID="http://schemas.microsoft.com/sharepoint/v3" StaticName="FullName" ColName="nvarchar6" Required="FALSE" Hidden="TRUE" ReadOnly="FALSE" PITarget="" PrimaryPITarget="" PIAttribute="" PrimaryPIAttribute="" Aggregation="" Node="" />
The properties ColName="<>" and ID="{<>}" are supposed to be unique for every line that exists in the document.
How can I loop through each line and and see if the values inside ColName and ID appears more than once(preferrably though C#)?

Treating it like code golf... to get duplicate elements:
var duplicateElements = XDocument.Load(pathToDocument).Root.Elements()
.GroupBy(el => String.Format("{0}|{1}", el.Attribute("ID").Value, el.Attribute("ColName").Value)))
.Where((val, e) => val.Count() > 1);
