XML Combing Duplicate IDs to a single XML and removing the duplicate

I have an XML file with several customers. When the customer ID is duplicated, I want to take the service from the duplicate customer record and add it to the initial customer record. I'm trying to do this in C#.
So the following two records:
<customer ID="200054598540" phone="352-555-1234" name="PAULSON ROBERT">
<services>
<service type="Electric" premise="5000001234" priority="0" />
</services>
<customFields>
<customField key="address" value="1521 NE 23RD AVE" />
<customField key="connection" value="CONNECTED" />
</customFields>
</customer>
<customer ID="200054598540" phone="352-555-1234" name="PAULSON ROBERT">
<services>
<service type="Water" premise="5000001235" priority="0" />
</services>
<customFields>
<customField key="address" value="1521 NE 23RD AVE" />
<customField key="connection" value="CONNECTED" />
</customFields>
</customer>
Become one, and it removes the duplicate, leading to:
<customer ID="200054598540" phone="352-555-1234" name="PAULSON ROBERT">
<services>
<service type="Electric" premise="5000001234" priority="0" />
<service type="Water" premise="5000001235" priority="0" />
</services>
<customFields>
<customField key="address" value="1521 NE 23RD AVE" />
<customField key="connection" value="CONNECTED" />
</customFields>
</customer>

var customers = doc.Descendants("customer").GroupBy(x => (string)x.Attribute("ID")).ToList();

//List<XElement> customFields = account.Descendants("customField").ToList();

account.Remove();
}
}
doc.Save(#"c:\customer_premise_osi_oms\customers_dupe.xml");
}

if (sigNode != null)
{
Console.WriteLine(sigNode.InnerText);
}
can you please tell me what's the problem and how to fix it?

Your Xml document uses the default namespace "http://schemas.hp.com/SM/7". You need to use the XmlNamespaceManager to select that node under this namespace.
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(#"C:\zzx\Project\SM\R5.1\Harness\InBound.xml");
var namespaceManager = new XmlNamespaceManager(xmlDoc.NameTable);
namespaceManager.AddNamespace("ns", "http://schemas.hp.com/SM/7");
XmlNode sigNode = xmlDoc.SelectSingleNode("//ns:UpdateInboundim613Response//ns:model//ns:instance//ns:OVSCTicketID",namespaceManager);
if (sigNode != null)
{
Console.WriteLine(sigNode.InnerText);
}
Above code should work fine.

LINQ query for XML c#

I have simple loop for finding child Element:
XDocument xDoc = XDocument.Load(#"bpmn.xml");
//Run query
foreach (XElement level1Element in xelement.Elements("process"))
{
System.Diagnostics.Debug.WriteLine(level1Element.Attribute("id").Value);
foreach (XElement level2Element in level1Element.Elements("task"))
{
System.Diagnostics.Debug.WriteLine(
" " + level2Element.Attribute("name").Value);
}
}
Why don't I get any output?

You need to get the root element first, by xDoc.Root (if xelement in your code is xDoc)
(The main problem here) Your XML has a custom namespace, in which case you need to specify it when calling Elements().
Putting together:
XDocument xDoc = XDocument.Load(#"bpmn.xml");
var ns = XNamespace.Get("http://www.omg.org/spec/BPMN/20100524/MODEL");
//Run query
foreach(XElement level1Element in xDoc.Root.Elements(ns + "process"))
{
System.Diagnostics.Debug.WriteLine(level1Element.Attribute("id").Value);
foreach(XElement level2Element in level1Element.Elements(ns + "task"))
{
System.Diagnostics.Debug.WriteLine(" " + level2Element.Attribute("name").Value);
}
}

You need to select from the root element. Try changing:
xelement.Elements("process"))
To:
xDoc.Elements("definitions").Elements("process")

Your .xml file provided with namespace, still you should use it in your code. Please try this:
XDocument xDoc = XDocument.Load(#"xmlfile1.xml");
//Run query
XNamespace ns = "http://www.omg.org/spec/BPMN/20100524/MODEL";
foreach (XElement level1Element in xDoc.Descendants(ns + "process"))
{
System.Diagnostics.Debug.WriteLine(level1Element.Attribute("id").Value);
foreach (XElement level2Element in level1Element.Elements(ns + "task"))
{
System.Diagnostics.Debug.WriteLine(
" " + level2Element.Attribute("name").Value);
}
}
Also, in your case use Descendants() method instead of Elements().

how to delete specific nodes and their children based on attributes in the parent node?

first, sorry for my bad english, i'm learning yet. So, I have to delete specifics nodes of a xml file according with their attributes. This is the xml file:
<?xml version="1.0" encoding="utf-8"?>
<Lista>
<Indice value="8">
<Palavra value="casa" />
<Significados>s1,,,,</Significados>
</Indice>
<Indice value="49">
<Palavra value="teste" />
<Significados>1,2,,,</Significados>
</Indice>
<Indice value="72">
<Palavra value="cristiano" />
<Significados>ornelas,ribeiro,,,</Significados>
</Indice>
<Indice value="72">
<Palavra value="teste2" />
<Significados>s2,s3,,,</Significados>
</Indice>
</Lista>
I have to delete all Indice nodes and your childrens that have the attribute value="72" for example. How can I do that? The language is c# and the xml file after of delete must stay in this form:
<?xml version="1.0" encoding="utf-8"?>
<Lista>
<Indice value="8">
<Palavra value="casa" />
<Significados>s1,,,,</Significados>
</Indice>
<Indice value="49">
<Palavra value="teste" />
<Significados>1,2,,,</Significados>
</Indice>
</Lista>

XDocument xdoc=XDocument.Parse(xmlStr); //or XDocument.Load
var matchingElements = xdoc.Root
.Descendants("Indice")
.Where(e => (int)e.Attribute("value") == 72)
.ToList();
foreach(var elem in matchingElements)
{
elem.Remove();
}
xdoc.Save(newFileName);
saves the following doc:
<Lista>
<Indice value="8">
<Palavra value="casa" />
<Significados>s1,,,,</Significados>
</Indice>
<Indice value="49">
<Palavra value="teste" />
<Significados>1,2,,,</Significados>
</Indice>
</Lista>

This is an alternative to Spender although he should get the question answered if his works.
XmlDocument doc = new XmlDocument();
doc.Load("xml path");
XmlNode node = doc.SelectSingleNode("/Lista");
foreach (XmlNode nodes in node.SelectNodes("Indice/#value"))
{
if (nodes.Value == "72")
{
nodes.RemoveAll();
}
}

how to check if xml document has a certain list of attributes?

i am experimenting with C# and xml, i am trying to read a XML file i want to validate if "NumberOfDays" , "NumberOfBooks", "NumberOfExam", "CurrentDate" are existing, if missing. i want to add them with there values.
i have the following xmldocument :
<?xml version="1.0" encoding="utf-8" ?>
<MySample>
<Content>
<add key="NumberOfDays" value="31" />
<add key="NumberOfBooks" value="20" />
<add key="NumberOfExam" value="6" />
<add key="CurrentDate" value="15 - Jul - 2011" />
</Content>
</MySample>
i am writing a sample application in c# using
--------Edit--------
thank you AresAvatar for your responce.
but if the value exists i would like to update its value i.e. if let's say
<add key="NumberOfExam" value="" />
i want to change the value to 6

You can get a list of which nodes exist like this:
// Get a list of which nodes exist
XmlDocument doc = new XmlDocument();
doc.LoadXml(myXml);
List<string> existingNodes = new List<string>();
XmlNodeList bookNodes = doc.SelectNodes("/MySample/Content/add");
foreach (XmlNode nextNode in bookNodes)
{
foreach (XmlAttribute nextAttr in nextNode.Attributes)
existingNodes.Add(nextAttr.InnerText);
}
You can add missing nodes like this:
// Add nodes
XmlNode addRoot = doc.SelectSingleNode("/MySample/Content");
XmlElement addme = doc.CreateElement("add");
addme.SetAttribute("NumberOfDays", "31");
addRoot.AppendChild(addme);
You can set the value of existing nodes like this:
// Update a node
foreach (XmlNode nextNode in bookNodes)
{
foreach (XmlAttribute nextAttr in nextNode.Attributes)
{
switch (nextAttr.Name)
{
case "NumberOfDays":
((XmlElement)nextNode).SetAttribute("value", "31");
break;
// etc.
}
}
}

First of all, if you have control over the generated XML (if you make it yourself), avoid using this schema:
<?xml version="1.0" encoding="utf-8" ?>
<MySample>
<Content>
<add key="NumberOfDays" value="31" />
<add key="NumberOfBooks" value="20" />
<add key="NumberOfExam" value="6" />
<add key="CurrentDate" value="15 - Jul - 2011" />
</Content>
</MySample>
It's much easier to use with that schema:
<?xml version="1.0" encoding="utf-8" ?>
<MySample>
<Content>
<Adds>
<NumberOfDays>31<NumberOfDays/>
<NumberOfBooks>20<NumberOfBooks/>
<NumberOfExam>6<NumberOfExam/>
<CurrentDate>5 - Jul - 2011<CurrentDate/>
</Adds>
</Content>
</MySample>
And then:
XmlDocument doc = new XmlDocument();
doc.Load("YourXmlPath");
XmlNode firstNode = doc["MySample"];
if(firstNode != null)
{
XmlNode secondNode = firstNode["Content"];
if(secondNode != null)
{
XmlNode thirdNode = secondNode["Adds"];
if(thirdNode != null)
{
if(thirdNode["NumberOfDays"] == null) //The "NumberOfDays" node does not exist, we create it.
{
XmlElement newElement = doc.CreateElement("NumberOfDays");
newElement.InnerXml = 31;
thirdNode.AppendChild(newElement);
}
//Do the same for the other nodes...
}
}
}
doc.Save("YourXmlPath");
Just remember to check for null on every node, or put the whole block into a try/catch.
And to save the XML once you did your changes.
XmlDocument.Load() function loads the XML in memory, so you can check for any node without making "blind loops".
