I have my XML as:
<root>
<element>
<id>1</id>
<group>first</group>
</element>
<element>
<id>2</id>
<group>second</group>
</element>
<element>
<id>3</id>
<group>first</group>
</element>
</root>
Is there anyway we can group the nodes with same values like this:
<root>
<groups name="first">
<element>
<id>1</id>
<group>first</group>
</element>
<element>
<id>3</id>
<group>first</group>
</element>
</groups>
<groups name="second"><element>
<id>2</id>
<group>second</group>
</element>
</groups>
</root>
Is there a way to group it based on same node values?
I just tested the code below and it matches your results.
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 xml =
"<root>" +
"<element>" +
"<id>1</id>" +
"<group>first</group>" +
"</element>" +
"<element>" +
"<id>2</id>" +
"<group>second</group>" +
"</element>" +
"<element>" +
"<id>3</id>" +
"<group>first</group>" +
"</element>" +
"</root>";
XDocument doc = XDocument.Parse(xml);
var groups = doc.Descendants("element")
.GroupBy(x => (string)x.Element("group"))
.ToList();
XElement newXml = new XElement("root");
foreach(var group in groups)
{
newXml.Add(new XElement("groups", new object[] {
new XAttribute("name", group.Key),
group
}));
}
}
}
}
XPath approach
string val= "first";
XmlDocument doc = new XmlDocument();
doc.Load(Server.MapPath("./Xml/YourXML.xml"));
string text = string.Empty;
XmlNodeList xnl = doc.SelectNodes("/root/groups ");
foreach (XmlNode node in xnl)
{
text = node.Attributes["name"].InnerText;
if (text == val)
{
XmlNodeList xnl = doc.SelectNodes(string.Format("/root/groups [#name='{0}']/element", val));
foreach (XmlNode node2 in xnl )
{
text = text + "<br>" + node2["id"].InnerText;
text = text + "<br>" + node2["group"].InnerText;
}
}
Response.Write(text);
}
or
var nodes = (from n in xml.Descendants("element").
Where(r => r.Parent.Attribute("name").Value == "first")
select new
{
id = (string)n.Element("id").Value,
group = (string)n.Element("group").Value
}).ToList();
Group the elements and build up a new document placing each group in a new <groups> element.
var newDoc = new XDocument(
new XElement("root",
from e in doc.Descendants("element")
group e by (string)e.Element("group") into g
select new XElement("groups",
new XAttribute("name", g.Key),
g
)
)
);
I had to try this in VB. My Group By skills need a lot of practice.
Using this test data
Dim myXML As XElement
myXML = <root>
<element>
<id>1</id>
<group>first</group>
</element>
<element>
<id>2</id>
<group>second</group>
</element>
<element>
<id>3</id>
<group>first</group>
</element>
</root>
this seems to work
Dim newXML As XElement = <root></root>
newXML.Add(From el In myXML.Elements
Order By el.<group>.Value
Group By gn = el.<group>.Value Into g = Group
Select New XElement("Groups", New XAttribute("name", gn), g))
newXML =
<root>
<Groups name="first">
<element>
<id>1</id>
<group>first</group>
</element>
<element>
<id>3</id>
<group>first</group>
</element>
</Groups>
<Groups name="second">
<element>
<id>2</id>
<group>second</group>
</element>
</Groups>
</root>

I Have below XML as an input
<Details>
<PAY>
<Mode>xyz</Mode>
<REMARKS>no</REMARKS>
</PAY>
<data>
<Customer>
<Participant>
<Participant1FirstName>aaaa</Participant1FirstName>
<Participant1LastName>zzzz</Participant1LastName>
</Participant>
<Participant>
<Participant2FirstName>bbbb</Participant2FirstName>
<Participant2LastName>yyyy</Participant2LastName>
</Participant>
<Participant>
<Participant3FirstName>cccc</Participant3FirstName>
<Participant3LastName>xxxx</Participant3LastName>
</Participant>
</Customer>
</data>
</Details>
Desired output :
String strOutput = "|Participant1FirstName = aaaa|Participant1LastName = zzzz|; |Participant2FirstName = bbbb|Participant2LastName = yyyy|; |Participant3FirstName = cccc|Participant3LastName = xxxx|"
SO far, I have tried parsing XML string into XDocument, and thinking of using Linq to get the desired output, but don't know the way forward.
Input :
string strXML = "<Details> <PAY> <Mode>xyz</Mode> <REMARKS>no</REMARKS> </PAY> <data> <Customer> <Participant> <Participant1FirstName>aaaa</Participant1FirstName> <Participant1LastName>zzzz</Participant1LastName> </Participant> <Participant> <Participant2FirstName>bbbb</Participant2FirstName> <Participant2LastName>yyyy</Participant2LastName> </Participant> <Participant> <Participant3FirstName>cccc</Participant3FirstName> <Participant3LastName>xxxx</Participant3LastName> </Participant> </Customer> </data></Details>"
XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(strXML);
Edit
Any way I can get desired output from below XML ?
<Details>
<PAY>
<Mode>xyz</Mode>
</PAY>
<data>
<Customer>
<Participant>
<Participant1>
<Participant1FirstName>aaaa</Participant1FirstName>
<Participant1LastName>zzzz</Participant1LastName>
</Participant1>
<Participant2>
<Participant2FirstName>bbbb</Participant2FirstName>
<Participant2LastName>yyyy</Participant2LastName>
</Participant2>
<Participant>
</Customer>
</data>
</Details>
You could do it like this
XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(strXML);
var values = xdoc.Descendants("Participant").Elements()
.Select(x => x.Name + " = " + x.Value).ToList();
string result = string.Join("|", values);
Try following :
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);
List<Particapant> participants = doc.Descendants("Participant").Select(x => new Particapant()
{
firstName = (string)x.Elements().FirstOrDefault(),
lastName = (string)x.Elements().LastOrDefault()
}).ToList();
string output = string.Join(";", participants
.Select(x => string.Format("|ParticipantFirstName = {0}|ParticipantLastName = {1}|", x.firstName, x.lastName)));
}
}
public class Particapant
{
public string firstName { get; set; }
public string lastName { get; set; }
}
}
I've created a program to retrieve data from a database and convert it to XML. It returns a list of 24 objects that I created:
<?xml version = "1.0" encoding = "utf-16"
<ArrayOfData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Data>
<interval>01</interval>
<num>12345</num>
<id>ABC123 </id>
<type>LETTER</type>
<party>1</party>
<amount>-10</amount>
</Data>
<Data>
<interval>02</interval>
<num>12345</num>
<id>ABC123 </id>
<type>LETTER</type>
<party>1</party>
<amount>-11</amount>
</Data>
<Data>
<interval>03</interval>
<num>12345</num>
<id>ABC123 </id>
<type>LETTER</type>
<party>1</party>
<amount>-12</amount>
</Data>
<Data>
<interval>04</interval>
<num>12345</num>
<id>ABC123 </id>
<type>LETTER</type>
<party>1</party>
<amount>-13</amount>
</Data>
Basically the data goes on with incrementing intervals by 1 up to 24.
What I am looking for is to look for what is duplicate and just concatenate them into one child, and then to look for what differs and create a different element for it but keep them everything in one child. How can I write the XML to do this? Example:
<Data>
<num>12345</num>
<id>ABC123 </id>
<type>LETTER</type>
<party>1</party>
<details>
<interval>01</interval>
<amount>-10</amount>
</details>
<details>
<interval>02</interval>
<amount>-11</amount>
</details>
<details>
<interval>03</interval>
<amount>-12</amount>
</details>
<details>
<interval>04</interval>
<amount>-13</amount>
</details>
</Data>
I want to create a function that returns this XML. The parameters in my current function now are just there to get the data using those parameters. Here's how I generate the XML now:
public IActionResult CreateXML(int num, int id)
{
string xml = "";
var temp = (from x in Context.InternalData.AsNoTracking() where (x.num == num && x.id == id) select x).ToList();
using (var stringwrite = new Utf8StringWriter())
{
var serializer = new XmlSerializer(temp.GetType());
serializer.Serialize(stringwrite, temp);
xml = stringwrite.ToString();
StringReader reader = new StringReader(stringwriter.ToString());
reader.ReadLine(); //skips the UTF-16 header
XDocument doc = XDocument.Load(reader);
XElement arrayOfData = doc.Root;
List<XElement> newData = new List<XElement>();
var parties = doc.Descendants("Data")
.GroupBy(x => (string)x.Element("id"))
.ToList();
foreach (var party in parties)
{
XElement template = party.First();
List<XElement> details = party.Select(x => new XElement("details", new object[] {
new XElement("interval", (string)x.Element("interval")),
new XElement("amount", (string)x.Element("amount"))
})).ToList();
template.Element("interval").Remove();
template.Element("amount").Remove();
template.Add(details);
newData.Add(template);
}
arrayOfData.ReplaceAll(newData);
return Ok(arrayOfData);
}
}
I am new to this and have never worked with generating XML before. Any help would be greatly appreciated!
Try xml linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
string xml = File.ReadAllText(FILENAME);
StringWriter stringwriter = new StringWriter();
stringwriter.Write(xml);
StringReader reader = new StringReader(stringwriter.ToString());
reader.ReadLine(); //skips the UTF-16 header
XDocument doc = XDocument.Load(reader);
XElement arrayOfData = doc.Root;
List<XElement> newData = new List<XElement>();
var parties = doc.Descendants("Data")
.GroupBy(x => (string)x.Element("id"))
.ToList();
foreach (var party in parties)
{
XElement template = party.First();
List<XElement> details = party.Select(x => new XElement("details", new object[] {
new XElement("interval", (string)x.Element("interval")),
new XElement("amount", (string)x.Element("amount"))
})).ToList();
template.Element("interval").Remove();
template.Element("amount").Remove();
template.Add(details);
newData.Add(template);
}
arrayOfData.ReplaceAll(newData);
}
}
}
I have following SOAP response. Using my code I could only extract one element.
and then it throws null reference exception error.
How do I extract Item->key and Item->value in to my dictionary in the function in C#?
Following is a part of the function which i use to extract data from.

</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The codes,
try
{
XmlDocument xdoc = new XmlDocument();//xml doc used for xml parsing
xdoc.LoadXml(content); // --------> THIS IS WHERE I PASS SOAP RESPONSE
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xdoc.NameTable);
nsmgr.AddNamespace("SOAP-ENV:encodingStyle", "http://schemas.xmlsoap.org/soap/encoding/");
XmlNodeList xNodelst = xdoc.DocumentElement.SelectNodes("//item");
int nodes = xNodelst.Count;
dynamic item;
Dictionary<string, string> items = new Dictionary<string, string>();
foreach (XmlNode xn in xNodelst)
{
XmlNode itemnode = xn["item"];
if (itemnode != null) {
string key = itemnode["key"].InnerText;
string value = itemnode["value"].InnerText;
items.Add(key, value);
}
}
var ss = items;
return "";
}
catch (Exception e) {
return e.Message;
}
The xml has two level of the tag item. So you have to make sure you treat each level of the item tag separately. I used xml linq to get data and put results into a dictionary.
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 root = doc.Root;
XNamespace ns = root.GetDefaultNamespace();
XElement firstItem = doc.Descendants(ns + "item").FirstOrDefault();
Dictionary<string, string> dictItems = firstItem.Descendants(ns + "item")
.GroupBy(x => (string)x.Element("key"), y => (string)y.Element("value"))
.ToDictionary(x => x.Key, y => y.FirstOrDefault());
}
}
}
I finally managed to make this work. I added all the namespaces in namespace manager variable. And used xPath to navigate through the XML as below,
XmlNodeList xNodelst = xdoc.DocumentElement.SelectNodes("//item[#xsi:type]",nsmgr);
This helped me to resolve my problem. I'm posting this here in case if anyone having similar issue.
Cheers!

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>

<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 :

My xml will be like below
<Employee>
<Emp>
<Name id="1" link="/office1/manager"></Name>
<Name id="2" link="/office/sweeper"></Name>
<Name id="3" link="/office2/manager"></Name>
</Emp>
</Employee>
I want to get the "id" of the employees who contains string "manager" in "link"
Using linq to xml:
XDocument doc = XDocument.Load("XMLFilePath");
var selectors = from elements in doc.Elements("Employee").Elements("Emp").Elements("Name")
where elements.Attribute("link").Value.Contains("manager")
select elements;
string ids = string.Empty;
foreach (var element in selectors)
{
ids += element.Attribute("id").Value + ",";
}
Also, for loading from string you can use:
XDocument doc = XDocument.Parse(xmlString);
var xDoc = XDocument.Parse(xml); //XDocument.Load(filename)
var ids = xDoc.Descendants("Name")
.Where(n => n.Attribute("link").Value.Contains("/manager"))
.Select(n => n.Attribute("id").Value)
.ToList();
