Unable to parse and read xml data

I have xml format as below. And trying to read elements from content, product name and product id but unable to. Here is what I have tried so far but no luck. Both of my approaches are not working any help is appreciated.
<source xml:base="https://google.com/api/v1" xmlns="http://www.w3.org/2005/Atom" >
<id>s1</id>
<value>
<id>value1</id>
<version>1.90</version>
<content type="application/xml">
<x:products>
<n:Productname>3M</n:Productname>
<n:ProductId n:type="Int32">97</n:ProductId>
</x:products>
<x:products>
<n:Productname>HD</n:Productname>
<n:ProductId n:type="Int32">99</n:ProductId>
</x:products>
</content>
</value>
</source>
FileStream fs = new FileStream(xmlFile, FileMode.Open, FileAccess.Read);
XmlDocument xmldoc = new XmlDocument();
XmlNodeList xmlnodecontent;
xmldoc.Load(fs);
xmlnodecontent = xmldoc.GetElementsByTagName("content");
for (int i = 0; i < xmlnodecontent.Count; i++)
{
var innerXml =xmlnodecontent[i].ChildNodes.Item(0).InnerXml;
//Trying to read product here
}
//Second approach
var doc = XDocument.Load(xmlFile);
var units = from u in doc.Descendants("value")
select new
{
Id = (int)u.Element("id"),
content = from entry in doc.Descendants("content")
select new
{
product = (int)u.Element("d:Product"),
}
};
foreach (var unit in units)
{
var id = unit.Id;
var content = unit.content;
}

I corrected the xml file and used xml linq (XDocument) to get values
<source xml:base="https://google.com/api/v1" xmlns="http://www.w3.org/2005/Atom" xmlns:x="abc" xmlns:n="def" >
<id>s1</id>
<value>
<id>value1</id>
<version>1.90</version>
<content type="application/xml">
<x:products>
<n:Productname>3M</n:Productname>
<n:ProductId n:type="Int32">97</n:ProductId>
</x:products>
<x:products>
<n:Productname>HD</n:Productname>
<n:ProductId n:type="Int32">99</n:ProductId>
</x:products>
</content>
</value>
</source>
Here is the code :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement value = doc.Descendants().Where(x => x.Name.LocalName == "value").FirstOrDefault();
XNamespace ns = value.GetDefaultNamespace();
XNamespace xNs = value.GetNamespaceOfPrefix("x");
XNamespace nNs = value.GetNamespaceOfPrefix("n");
var values = doc.Descendants(ns + "value").Select(x => new
{
id = (string)x.Element(ns + "id"),
products = x.Descendants(xNs + "products").Select(y => new
{
name = (string)y.Element(nNs + "Productname"),
id = (string)y.Element(nNs + "ProductId")
}).ToList()
}).ToList();
}
}
}

Create XML from SQL select query

I am trying to create a xml from a SQL select, but I can not insert ":" (like cac:PartyTaxScheme), neither can put 2 data in one element, look element "cbc:CompanyID" (<cbc:CompanyID schemeName="31" schemeID="0" schemeAgencyID="195">900711000</cbc:CompanyID> ), how can I do it ?
Next is the example I want to expect:
<cac:PartyTaxScheme>
<cbc:RegistrationName>GRUPO FAM</cbc:RegistrationName>
<cbc:CompanyID schemeName="31" schemeID="0" schemeAgencyID="195">900711000</cbc:CompanyID>
<cbc:TaxLevelCode listName="48">O-23</cbc:TaxLevelCode>
<cac:RegistrationAddress>
<cbc:ID>11001</cbc:ID>
<cbc:CountrySubentityCode>11</cbc:CountrySubentityCode>
<cac:AddressLine>
<cbc:Line>CaLL 90</cbc:Line>
</cac:AddressLine>
<cac:Country>
<cbc:IdentificationCode>CO</cbc:IdentificationCode>
</cac:Country>
</cac:RegistrationAddress>
</cac:PartyTaxScheme>
Thanks a lot

Using Xml Linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string ident = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>" +
"<cac:PartyTaxScheme xmlns:cac=\"URL1\" xmlns:cbc=\"URL2\">" +
"</cac:PartyTaxScheme>";
XDocument doc = XDocument.Parse(ident);
string registrationName = "GPUPO FAM";
string schemeName = "31";
string schemeID = "0";
string schemeAgencyID = "195";
string companyID = "900711000";
string listName = "48";
string taxLevelCode = "0-23";
string ID = "11001";
string countrySubentityCode = "11";
string address = "CaLL 90";
string identificationCode = "CO";
XElement partyTaxScheme = doc.Root;
XNamespace nsCac = partyTaxScheme.GetNamespaceOfPrefix("cac");
XNamespace nsCbc = partyTaxScheme.GetNamespaceOfPrefix("cbc");
XElement xRegistrationName = new XElement(nsCac + "RegistrationName", registrationName);
partyTaxScheme.Add(xRegistrationName);
XElement xCompanyID = new XElement(nsCbc + "CompanyID", new object[] {
new XAttribute("scnemeName", schemeName),
new XAttribute("schemeID", schemeID),
new XAttribute("schemeAgencyID", schemeAgencyID),
companyID
});
partyTaxScheme.Add(xCompanyID);
XElement xTaxLevelCode = new XElement(nsCbc + "TaxLevelCode", new object[] {
new XAttribute("listName", listName),
taxLevelCode
});
partyTaxScheme.Add(xTaxLevelCode);
XElement xRegistrationAddress = new XElement(nsCac + "RegistrationAddress");
partyTaxScheme.Add(xRegistrationAddress);
xRegistrationAddress.Add(new XElement(nsCbc + "ID", ID));
xRegistrationAddress.Add(new XElement(nsCbc + "CountrySubentityCode", countrySubentityCode));
xRegistrationAddress.Add(new XElement(nsCac + "AddressLine", new XElement(nsCbc + "Line", address)));
xRegistrationAddress.Add(new XElement(nsCac + "Country", new XElement(nsCbc + "IdentificationCode", countrySubentityCode)));
}
}
}

C# Xdocument Xml get Element

I have a xml file that looks like this:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<GetAllArticlesResponse xmlns="http://www.borger.dk/2009/WSArticleExport/v1">
<GetAllArticlesResult xmlns:a="http://www.borger.dk/2009/WSArticleExport/v1/types" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<a:ArticleDescription>Test 1</a:ArticleDescription>
<a:ArticleDescription>Test 2</a:ArticleDescription>
</GetAllArticlesResult>
</GetAllArticlesResponse>
</s:Body>
</s:Envelope>
I'm trying to get all the articles, but can't get it to work.
XDocument doc = XDocument.Parse(soapResult);
IEnumerable<XElement> articles = doc.Root.Descendants("a:ArticleDescription");
This has work before, but because the element name as a : then it fails..
Any idea how to fix this.
Thanks for all the inputs.
I ended with::
XNamespace a = "http://www.borger.dk/2009/WSArticleExport/v1/types";
XDocument doc = XDocument.Parse(soapResult);
IEnumerable<XElement> articles = doc.Root.Descendants(a + "ArticleDescription");
List<Article> article = articles.Select(m => new Article()
{
ArticleID = m.Element(a + "ArticleID").Value.ToString(),
ArticleTitle = m.Element(a + "ArticleTitle").Value.ToString(),
ArticleUrl = m.Element(a + "ArticleUrl").Value.ToString(),
LastUpdated = m.Element(a + "LastUpdated").Value.ToString(),
PublishingDate = m.Element(a + "PublishingDate").Value.ToString()
}).ToList();
json = JsonConvert.SerializeObject(article);

Here's an alterante way:
var doc = XDocument.Load(xml);
XNamespace ns1 = "http://schemas.xmlsoap.org/soap/envelope/";
XNamespace ns2 = "http://www.borger.dk/2009/WSArticleExport/v1";
XNamespace ns3 = "http://www.borger.dk/2009/WSArticleExport/v1/types";
var result = doc.Element(ns1 + "Envelope")
.Element(ns1 + "Body")
.Element(ns2 + "GetAllArticlesResponse")
.Element(ns2 + "GetAllArticlesResult")
.Elements(ns3 + "ArticleDescription")
.Select(x => x.Value);
Or
var doc = XDocument.Load(xml);
var envelope = doc.Root;
var body = (XElement)envelope.FirstNode;
var getAllArticlesResponse = (XElement)body.FirstNode;
var getAllArticlesResult = (XElement)getAllArticlesResponse.FirstNode;
var articleDescriptions = getAllArticlesResult.Nodes().Cast<XElement>();
var result = articleDescriptions.Select(x => x.Value);

Here is easiest way using Xml Linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication137
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
string[] description = doc.Descendants().Where(x => x.Name.LocalName == "ArticleDescription").Select(x => (string)x).ToArray();
}
}
}

The prefix a: is a short-for of the namespace name "http://www.borger.dk/2009/WSArticleExport/v1/types", you can see that where the prefix is declared.
You can use namespace-aware XName's when querying:
var descriptions = doc.Root.Descendants(
XName.Get("ArticleDescription", "http://www.borger.dk/2009/WSArticleExport/v1/types"));
Of course you could store the namespaces you want in variables, you don't have to type them out every time.
You can also just look at the local names, if you're not worried about collisions.
var descriptions = doc.Root.Descendants().Where(x => x.Name.LocalName == "ArticleDescription");

Get value from simple XML document

I have the following XML
<User
xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/GaryLeaderboardsAPI.Models">
<Game_ID>3</Game_ID>
<UserGUID>e00d3560-4133-4ba6-8bba-e6c8659468b4</UserGUID>
<UserName>tony2</UserName>
<User_ID>16</User_ID>
</User>
Using C# I am loading this into an XMLDocument, How do I retrieve the UserGUID value?

Leveraging System.Xml.Linq you could do
string xml = "..."; // your inline XML
var doc = System.Xml.Linq.XDocument.Parse(xml);
or
string xmlFile = "..."; // your XML filename
var doc = System.Xml.Linq.XDocument.Load(xmlFile);
and then, to get the UserGUID
var userGuid = doc.Descendants().Where(x=>x.Name.LocalName == "UserGUID").First().Value;

This will work for you.
string xml = "<User xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns=\"http://schemas.datacontract.org/2004/07/GaryLeaderboardsAPI.Models\">" +
"<Game_ID>3</Game_ID>" +
"<UserGUID>e00d3560-4133-4ba6-8bba-e6c8659468b4</UserGUID>" +
"<UserName>tony2</UserName>" +
"<User_ID>16</User_ID>" +
"</User>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
var id = doc.GetElementsByTagName("UserGUID")[0].InnerText;

You need to use the namespace. I often use mipnw approach (probably stole idea from one of my postings). See code below :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement user = doc.Root;
XNamespace ns = user.GetDefaultNamespace();
string UserGUID = (string)user.Element(ns + "UserGUID");
}
}
}

Reading XML with namespace and repeating nodes

I have the following XML:
<resource>
<description>TTT</description>
<title>TEST</title>
<entity xmlns="TdmBLRuPlUz.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xlink="http://www.w3.org/1999/xlink" xsi:schemaLocation="TdmBLRuPlUz.xsd TdmBLRuPlUz.xsd">
<UzdProd>
<row>
<F_DAUDZ>50</F_DAUDZ>
<BR_DAUDZ/>
<DAUDZ>50</DAUDZ>
<U_DAUDZ/>
<NKODS>ST2.0_014_023</NKODS>
</row>
</UzdProd>
<UzdMat>
<row>
<NKODS>SAG 2.0_014_150</NKODS>
<NNOSAUK>Sagatave 2.0mm*0.14*150m</NNOSAUK>
<PK_VIEN>1</PK_VIEN>
<DAUDZ>0.077</DAUDZ>
<F_DAUDZ>0.077</F_DAUDZ>
</row>
</UzdMat>
</entity>
</resource>
And this is my C# code:
XNamespace ns = "TdmBLRuPlUz.xsd";
XDocument doc = XDocument.Parse(xml);
foreach (XElement element in doc.Descendants(ns + "row"))
{
Console.WriteLine(element.Element(ns + "NKODS").Value);
string NKODS = element.Element(ns + "NKODS").Value;
string F_DAUDZ = element.Element(ns + "F_DAUDZ").Value;
string DAUDZ = element.Element(ns + "DAUDZ").Value;
}
What I need is to read values from the XML nodes NKODS, F_DAUDZ and DAUDZ.
The problem is that there are repeating nodes with those names and with this code it gives me the last ones which are under UzdMat node. What would be the way to get the values for these nodes under UzdProd?
I tried to change row to UzdProd, but that didn't work.

You need to read the specific row you want rather than looping through all of them. For example:
var prodRow = doc.Descendants(ns + "UzdProd").Elements(ns + "row").Single();
var matRow = doc.Descendants(ns + "UzdMat").Elements(ns + "row").Single();
var prodNkods = (string) prodRow.Element(ns + "NKODS");
var matNkods = (string) matRow.Element(ns + "NKODS");
See this fiddle for a working demo.

See if this works :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication25
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement entity = doc.Descendants().Where(x => x.Name.LocalName == "entity").FirstOrDefault();
XNamespace ns = entity.GetDefaultNamespace();
var results = entity.Elements().Select(x => new {
uzd = x.Name.LocalName,
dict = x.Descendants(ns + "row").Elements().GroupBy(y => y.Name.LocalName, z => (string)z)
.ToDictionary(y => y.Key, z => z.FirstOrDefault())
}).ToList();
}
}
}
