Hi everyone!

I have a question regarding LinQ to XML and iterating through a list.

This is my code so far:

C#

new XElement("caption", data.ToList().Select(x => x))

What this is doing is printing an XElement statement with everything in the list "data". What my intent is is to have one XElement statement per element in the list (sort of recursive fashion). Can anyone shed some light as to what I'm doing wrong?

Thanks everyone!

You need to iterate through data and yield an XElement for each item.

C#

var result = new XElement("captions", data.Select(x => new XElement("caption", x)));

This will generate the result like,

XML

<captions>
  <caption>a</caption> 
  <caption>b</caption> 
  <caption>c</caption> 
</captions>

In your scenarion it assumes, there is a single node

XML

<caption></caption>

with a value of

C#

data.ToList().Select(x => x)
