The Code:
new XElement("Person"));
XElement items = xdoc.Root
foreach (ObservableCollection<Person> x in list)
{
XElement children = new XElement("List");
foreach (var person in x)
{
XElement person = new XElement("Person",
new XElement("Name", person.name),
new XElement("Surname", person.surn),
new XElement("City", person.city));
items.Add(person);
}
items.Add(children);
}
xdoc.Save(path);
But in XML it looks like that:
<Pepole>
<Person>
<name>d</name>
<surname>a</surname>
<city>b</city>
</Person>
**<List />**
It's missing the start of the list - please any advice how to solve it?
Its very unclear what you want. You have a collection of lists of Person objects. Do you want a separate List tag for each List or all the Person tags to be within one List tag?
Well here's both:
All in one list:
XElement items = xdoc.Root
XElement bigList= new XElement("List");
items.Add(bigList);
foreach (ObservableCollection<Person> x in list)
{
foreach (var person in x)
{
XElement person = new XElement("Person",
new XElement("Name", person.name),
new XElement("Surname", person.surn),
new XElement("City", person.city));
bigList.Add(person);
}
}
xdoc.Save(path);
Individual list for each List:
XElement items = xdoc.Root
foreach (ObservableCollection<Person> x in list)
{
XElement smallList= new XElement("List");
items.Add(smallList);
foreach (var person in x)
{
XElement person = new XElement("Person",
new XElement("Name", person.name),
new XElement("Surname", person.surn),
new XElement("City", person.city));
smallList.Add(person);
}
}
xdoc.Save(path);
It's missing the start of the list
No - it's rendering an empty List tag . You added person to the root element instead of to the children element, so it gets rendered under the root instead of under List.

I got a dictionary with different propertys. Now I want to create a XML File out of this dictionary, but I dont know how I can iterate trough each entry in my dictionary.
In my dictionary there are 2 propertys called quantity and price.
So this is actually what my code looks like.
XDocument xDoc = new XDocument(
new XElement("itemlist",
new XElement("item",
new XAttribute("article", "1"),
new XAttribute("quantity", "150"),
new XAttribute("price", "20"))));
xDoc.Save("C:/Users/User/Desktop/XMLOutput.xml");
But I don't want to write every entry in my dictionary myself, so I'm looking for a solution something like this:
XDocument xDoc = new XDocument(
new XElement("itemlist",
foreach (KeyValuePair<string, item> it in dictionary_items)
{
new XElement("item",
new XAttribute("article", it.Key),
new XAttribute("quantity", it.Value.quantity),
new XAttribute("price", it.Value.price)
));
}
xDoc.Save("C:/Users/User/Desktop/XMLOutput.xml");
So I want to iterate trough each entry in my dictionary and write it as above in my XML-File. How can I do that?
Thanks for your help.
Sure. You can use XStreamingElement for this:
using System;
using System.Collections.Generic;
using System.Xml.Linq;
using System.Linq;
namespace ConsoleApp31
{
class Program
{
class Item
{
public int quantity { get; set; }
public double price { get; set; }
}
static void Main(string[] args)
{
var dictionary_items = new Dictionary<string, Item>();
dictionary_items.Add("abc", new Item() { quantity = 1, price = 3.3 });
dictionary_items.Add("def", new Item() { quantity = 1, price = 3.3 });
XDocument xDoc = new XDocument(
new XStreamingElement("itemlist",
from it in dictionary_items
select new XElement("item",
new XAttribute("article", it.Key),
new XAttribute("quantity", it.Value.quantity),
new XAttribute("price", it.Value.price)))
);
Console.WriteLine(xDoc.ToString());
Console.ReadKey();
}
}
}
outputs
<itemlist>
<item article="abc" quantity="1" price="3.3" />
<item article="def" quantity="1" price="3.3" />
</itemlist>
var list = new XElement("itemlist");
foreach (KeyValuePair<string, item> it in dictionary_items)
{
list.Add(new XElement("item",
new XAttribute("article", it.Key),
new XAttribute("quantity", it.Value.quantity),
new XAttribute("price", it.Value.price)
)));
}
XDocument xDoc = new XDocument(list);
xDoc.Save("C:/Users/User/Desktop/XMLOutput.xml");
I am trying to convert a list of objects into xml using XElement. My code is as below
var employees = new List<Employee>();
employees.Add(new Employee("1", " Ali","",1000));
employees.Add(new Employee("2", "Billy","",1001));
var xml = new XElement("root");
xml.Add(new XElement("Employees"));
foreach (var employee in employees)
{
xml.Add(new XElement("employee", employee.Name));
};
I want an output like this
<root>
<Employees>
<employee>Ali</employee>
<employee>Billy</employee>
</Employees>
</root>
but the output I m getting is
<root>
<Employees/>
<employee>Ali</employee>
<employee>Billy</employee>
</root>
I tried moving the Employees object inside the loop like below but that does not help either
foreach (var employee in employees)
{
xml.Add(new XElement("Employees", new XElement("employee", employee.Name)));
};
XElement constructor can handle IEnumerable so you can add employee elements at once while creating the parent Employees. In fact, the entire XML can be created at once :
var xml = new XElement("root",
new XElement("Employees",
employees.Select(e => new XElement("employee", e.Name))
)
);
Within your loop, you should call Add() on your employees element rather than on your root:
var employees = new List<Employee>();
employees.Add(new Employee("1", " Ali","",1000));
employees.Add(new Employee("2", "Billy","",1001));
var xml = new XElement("root");
var employeesElement = new XElement("Employees");
foreach (var employee in employees)
{
employeesElement.Add(new XElement("employee", employee.Name));
}
xml.Add(employeesElement);
I have a Collection of a class that looks like:
public class Group
{
public string Name { get; set; }
}
private ObservableCollection<Group> _groups;
now I want to create a xml structure from groups that looks like:
<Ou>
<Group>AAA</Group>
<Group>BBB</Group>
<Group>CCC</Group>
<Group>DDD</Group>
</Ou>
I have try following:
new XElement("Ou", //How continue here?)
but do not know how to continue coding.
Like this:
var element =
new XElement(
"Ou",
new XElement("Group", "AAA"),
new XElement("Group", "BBB"),
new XElement("Group", "CCC"),
new XElement("Group", "DDD"));
Or from your data structure:
var element =
new XElement("Ou",
from g in _groups
select new XElement("Group", g.Name));
new XElement("Ou", _groups.Select(g => new XElement("Group", g.Name)));
You can try following code:
var element = new XElement("Ou");
element.Add(new XElement("Group", "AAA"));
element.Add(new XElement("Group", "BBB"));
element.Add(new XElement("Group", "CCC"));
element.Add(new XElement("Group", "DDD"));
...
How to add the collection of items to XML Document ? Something I started trying, but it's wrong! I'll be grateful for the link on the Internet at a good tutorial too. Also, It is assumed that the iteration will be some elements.
Such code:
public static void Create_Interfaces()
{
XDocument Interfaces;
Interfaces = XDocument.Load("Interfaces.xml");
List<string> intf = new List<string>{"em0","em1","em2"};
foreach (var i in intf)
{
Interfaces = new XDocument(
new XElement("Interfaces",
new XElement("Interface",
new XElement("name", i),
new XElement("vlan-tagging", XElement.EmptySequence),
new XElement("unit",
new XElement("vlan-id", "10"),
new XElement("family", new XElement("inet", new XElement("address", new XElement("name", "10.10.1.23/24"))))))));
}
Interfaces.Save("Interfaces.xml");
}
Get your root element add new elements to it then save it:
var rootElement = Interfaces.Root;
foreach (var i in intf)
{
var element = new XElement("Interface",
new XElement("name", i),
new XElement("vlan-tagging", XElement.EmptySequence),
new XElement("unit",
new XElement("vlan-id", "10"),
new XElement("family",
new XElement("inet",
new XElement("address",
new XElement("name", "10.10.1.23/24"))))));
rootElement.Add(element);
}
rootElement.Save("Interfaces.xml");
So let's assume this is what i want to achieve:
<root>
<name>AAAA</name>
<last>BBBB</last>
<children>
<child>
<name>XXX</name>
<last>TTT</last>
</child>
<child>
<name>OOO</name>
<last>PPP</last>
</child>
</children>
</root>
Not sure if using XElement is the simplest way
but this is what I have so far:
XElement x = new XElement("root",
new XElement("name", "AAA"),
new XElement("last", "BBB"));
Now I have to add the "children" based on some data i have.
There could be 1,2,3,4 ...
so I need to iterate thru my list to get every single child
foreach (Children c in family)
{
x.Add(new XElement("child",
new XElement("name", "XXX"),
new XElement("last", "TTT"));
}
PROBLEM:
Doing this way I will be missing the "CHILDREN Parent node".
If I just add it before the foreach, it will be rendered as a closed node
<children/>
and that's NOT what we want.
QUESTION:
How can I add to the 1st part a parent node and as many as my list has?
Try this:
var x = new XElement("root",
new XElement("name", "AAA"),
new XElement("last", "BBB"),
new XElement("children",
from c in family
select new XElement("child",
new XElement("name", "XXX"),
new XElement("last", "TTT")
)
)
);
XElement root = new XElement("root",
new XElement("name", "AAA"),
new XElement("last", "BBB"));
XElement children = new XElement("children");
foreach (Children c in family)
{
children.Add(new XElement("child",
new XElement("name", c.Name),
new XElement("last", c.Last));
}
root.Add(children);
var children = new XElement("children");
XElement x = new XElement("root",
new XElement("name", "AAA"),
new XElement("last", "BBB"),
children);
foreach (Children c in family)
{
children.Add(new XElement("child",
new XElement("name", "XXX"),
new XElement("last", "TTT"));
}
