I am struggling to read this xml file in linq to xml. Can someone help me here.
I need to read each track information.
<playlist version="1" xmlns="http://xspf.org/ns/0/" xmlns:jwplayer="http://developer.longtailvideo.com/trac/wiki/FlashFormats">
<title>Some title here</title>
<creator>Some creater</creator>
<info>somesite.com</info>
<trackList>
<track>
<title>Title 1</title>
<creator>Creater 1</creator>
<location>location 1</location>
</track>
<track>
<title>Title 2</title>
<creator>Creater 2</creator>
<location>location 2</location>
</track>
</trackList>
</playlist>
This is what I am trying to do.
XElement xelement1 = XElement.Load(#"pathtoxmlfile\my.xml");
IEnumerable<XElement> tracks= xelement1.Elements();
// Read the entire XML
foreach (var track in tracks.Descendants("track"))
{
Console.WriteLine(track );
Console.ReadLine();
}
I am using C#.
Thanks

Why do you load your document into XElement instead of XDocument?
You have to use XNamespace instance within your query because your document uses default namespace xmlns="http://xspf.org/ns/0/".
var ns = XNamespace.Get("http://xspf.org/ns/0/");
You can use LINQ query to get a collection with your data extracted from XML document. Then you can iterate over that collection and do whatever you need.
var tracks = (from t in xDoc.Root.Element(ns + "trackList").Elements(ns + "track")
select new
{
Title = (string)t.Element(ns + "title"),
Creator = (string)t.Element(ns + "creator"),
Location = (string)t.Element(ns + "location")
}).ToList();
tracks will be a List<T> where T is anonymous type with 3 string properties: Title, Creator and Location.
You forget to include namespace name, do the following changes:
XNamespace defNs = "http://xspf.org/ns/0/";
And
foreach (var track in tracks.Descendants(defNs + "track"))
XElement tracks = XElement.Load(#"pathtoxmlfile\my.xml");
foreach (var track in tracks.Descendants("track"))
{
Console.WriteLine((string)track.Element("title"));
Console.WriteLine((string)track.Element("creator"));
Console.WriteLine((string)track.Element("location"));
}

Please help. How to read from xml sub tree. I have xml doc:
<data>
<Infos>
<Info>
<AddressFk>1</AddressFk>
<AddressLine1>1970</AddressLine1>
<AddressLine2>Napa Ct.</AddressLine2>
<Phone>
<dataAsString1>111111</string>
<dataAsString2>222222</string>
<dataAsString3>333333</string>
</Phone>
<City>Bothell</City>
</Info>
</Infos>
I read xml using XDocument:
XDocument xdoc = XDocument.Load("1.xml");
foreach (XElement addresList in xdoc.Document.Element("data").Elements("Infos").Elements("Info"))
{
address = new Address();
address.id = (string)addresList.Element("AddressFk");
address.Line1 = (string)addresList.Element("AddressLine1");
address.Line2 = (string)addresList.Element("AddressLine2");
address.City = (string)addresList.Element("City");
}
how to get the structure <Phone> ???
Use Elements
var phones = addresList.Element("Phone").Elements("string");
foreach(var phone in phones)
{
Console.WriteLine((string)phone);
}
for the future, it is bad practice to use tag names with reserved words
I am trying to read an xml file (and later import the data in to a sql data base) which contains employees names address' etc.
The issue I am having is that in the xml the information for the address for the employee the node names are all the same.
<Employee>
<EmployeeDetails>
<Name>
<Ttl>Mr</Ttl>
<Fore>Baxter</Fore>
<Fore>Loki</Fore>
<Sur>Kelly</Sur>
</Name>
<Address>
<Line>Woof Road</Line>
<Line>Woof Lane</Line>
<Line>Woofington</Line>
<Line>London</Line>
</Address>
<BirthDate>1985-09-08</BirthDate>
<Gender>M</Gender>
<PassportNumber>123756rt</PassportNumber>
</EmployeeDetails>
</Employee>
I all other items are fine to extract and I have tried to use Linq to iterate through each "Line" node but it always just gives be the first Line and not the others.
var xAddreesLines = xEmployeeDetails.Descendants("Address").Select(x => new
{
address = (string)x.Element("Line").Value
});
foreach (var item in xAddreesLines)
{
Console.WriteLine(item.address);
}
I need to able to when I'm importing to my sql db that address line is separate variable
eg
var addressline1 = first <line> node
var addressline2 = second <line> node etc etc.
Any advice would be most welcome.
This should give you the expected output:-
var xAddreesLines = xdoc.Descendants("Address")
.Elements("Line")
.Select(x => new { address = (string)x });
You need to simply fetch the Line elements present inside Address node and you can project them. Also note there is no need to call the Value property on node when you use explicit conversion.
You can do it like this:
using System.Xml;
.
.
.
XmlDocument doc = new XmlDocument();
doc.Load("source.xml");
// if you have the xml in a string use doc.LoadXml(stringvar)
XmlNamespaceManager nsmngr = new XmlNamespaceManager(doc.NameTable);
XmlNodeList results = doc.DocumentElement.SelectNodes("child::Employee", nsmngr);
foreach (XmlNode result in results)
{
XmlNode namenode = result.SelectSingleNode("Address");
XmlNodeList types = result.SelectNodes("line");
foreach (XmlNode type in types)
{
Console.WriteLine(type.InnerText);
}
XmlNode fmtaddress = result.SelectSingleNode("formatted_address");
}

I have a xml structure like this. Can anyone help with a simple linq function to read this xml structure.The itemEntry node repeats according to data. I tried to read the xml using the method below,but i am getting no records in the list. Is this method here correct way to get the details...
List<CX_ITEMLIST> sList =
(from e in XDocument.Load(param.FileName).Root.Elements("itemEntry")
select new CX_ITEMLIST
{
TITLE = (string)e.Element("title"),
YEAR = (string)e.Element("year"),
ITEMNAME = (string)e.Element("itemname"),
CATRYLIST =
(
from p in e.Elements("categorylist").Elements("categories")
select new CATLIST
{
IDTYPE = (string)p.Element("categoryid"),
IDNUMBER = (string)p.Element("categoryName")
}).ToList()
}).ToList();
<itemslist>
<itemInformation>
<itemdate>01/23/2014</itemdate>
<itemcount>57</itemcount>
</itemInformation>
<itemEntry>
<title>Title1</title>
<year>2013</title>
<itemname>testname</itemname>
<categorylist>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
</categorylist>
</itemEntry>
<itemEntry>
<title>Title1</title>
<year>2013</title>
<itemname>testname</itemname>
<categorylist>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
</categorylist>
</itemEntry>
</itemslist>
You should try with XDocument.
XDocument xdoc = XDocument.Load("file.xml");
The System.Xml.XLinq namespace contains some awesome objects to make this easy.
var xDoc = XDocument.Parse(xml); // load your xml string, or use XDocument.Load() to load an xml file
var itemEntries = xDoc
.Root // refers to itemEntries node
.Descendants("itemEntry"); // gets all itemEntry nodes in an IEnumerable object
This gets you an IEnumerable<XNode> of all the itemEntry nodes.
From there you can do what you need, save the values to a business object, etc.
The above method works properly, i found the issue, my xml tag was having namespace attribute. i tried to get the namespace and append it with Elements while reading
XNamespace ns = xDocument.Root.Attribute("xmlns").Value;
List<CX_ITEMLIST> sList =
(from e in XDocument.Load(param.FileName).Root.Elements(ns + "itemEntry")
select new CX_ITEMLIST
{
TITLE = (string)e.Element(ns + "title"),
YEAR = (string)e.Element(ns + "year"),
ITEMNAME = (string)e.Element(ns + "itemname"),
CATRYLIST =
(
from p in e.Elements(ns + "categorylist").Elements(ns + "categories")
select new CATLIST
{
IDTYPE = (string)p.Element(ns + "categoryid"),
IDNUMBER = (string)p.Element(ns + "categoryName")
}).ToList()
}).ToList();
I have the below XML as:
<Requests xmlResponse="true">
<Request response="yes" responsewait="120000" sequence="1" type="Fulfillment">
<RequestData>
<PrintControl>FTP</PrintControl>
<User>81DF</User>
<Documents>
<AddressChangeLetter>
<DocumentInfo>
<AddressChange AddressChangeId="109346" Branch="418" LastChangeDate="">
<Name>AAA NOVAK</Name>
<TaxID>123123121</TaxID>
<OldAddress1>BOX 216</OldAddress1>
<OldAddress2>NYANE 68017</OldAddress2>
<OldAddress3 />
<OldAddress4 />
<NewAddress1>P O BOX 216</NewAddress1>
<NewAddress2>CERESCO NE 68017</NewAddress2>
<NewAddress3 />
<NewAddress4 />
<DateChanged>05/08/2013</DateChanged>
<AccountInfo AcctNum="231232311" AcctStatusCodes="IX" />
</AddressChange>
</DocumentInfo>
</AddressChangeLetter>
</Documents>
</RequestData>
I wanted to get the name or the value which is under the tag "Documents". Since in the above XML, the tag under the "Document" tag is "AddressChangeLetter", therefore, I want to get this name. How will I do it.
Something along the lines of... (it's not perfect, but it'll get you started - Google the functions I've used to get it working properly):
XmlDocument xml = new XmlDocument();
xml.Load(yourPathGoesHere)
XmlNodeList addressNodes = xml.GetElementsByTagName("AddressChange");
foreach (XmlNode oneNode in addressNodes) {
myVariableToGrabNames = oneNode["Name"].InnerText;
}
This can be done pretty easily using Linq to XML e.g.
var xml = ...;
var xdoc = XDocument.Parse(xml);
foreach (var e in xdoc.Descendants("Documents").Elements())
{
var name = e.Name; // AddressChangeLetter
}
Let's say I have this XML file:
<Names>
<Name>
<FirstName>John</FirstName>
<LastName>Smith</LastName>
</Name>
<Name>
<FirstName>James</FirstName>
<LastName>White</LastName>
</Name>
</Names>
And now I want to print all the names of the node:
Names
Name
FirstName
LastName
I managed to get the all in a XmlNodeList, but I dont know how SelectNodes works.
XmlNodeList xnList = xml.SelectNodes(/*What goes here*/);
I want to select all nodes, and then do a foreach of xnList (Using the .Value property I assume).
Is this the correct approach? How can I use the selectNodes to select all the nodes?
Ensuring you have LINQ and LINQ to XML in scope:
using System.Linq;
using System.Xml.Linq;
If you load them into an XDocument:
var doc = XDocument.Parse(xml); // if from string
var doc = XDocument.Load(xmlFile); // if from file
You can do something like:
doc.Descendants().Select(n => n.Name).Distinct()
This will give you a collection of all distinct XNames of elements in the document. If you don't care about XML namespaces, you can change that to:
doc.Descendants().Select(n => n.Name.LocalName).Distinct()
which will give you a collection of all distinct element names as strings.
There are several ways of doing it.
With XDocument and LINQ-XML
foreach(var name in doc.Root.DescendantNodes().OfType<XElement>().Select(x => x.Name).Distinct())
{
Console.WriteLine(name);
}
If you are using C# 3.0 or above, you can do this
var data = XElement.Load("c:/test.xml"); // change this to reflect location of your xml file
var allElementNames =
(from e in in data.Descendants()
select e.Name).Distinct();
Add
using System.Xml.Linq;
Then you can do
var element = XElement.Parse({Your xml string});
Console.Write(element.Descendants("Name").Select(el => string.Format("{0} {1}", el.Element("FirstName").Value, el.Element("LastName").Value)));
