I have an XML file, in this XML you can see the RESPONSE_DATA tag. This tag have some more inner tags. I need to get all the values inside PERSON_DATA tags. Also i need to get all the other value in below xml file.
<?xml version=\"1.0\" encoding=\"utf-16\"?>\r\n
<HUMAN_VERIFICATION xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RESPONSE_DATA>
<RESPONSE_STATUS>
<ERROR>100</ERROR>
<MESSAGE>successful</MESSAGE>
</RESPONSE_STATUS>
<CONTACT_NUMBER>3120202456011</CONTACT_NUMBER>
<PERSON_DATA>
<NAME>Alex</NAME>
<DATE_OF_BIRTH>10-9-1982</DATE_OF_BIRTH>
<BIRTH_PLACE>Washington</BIRTH_PLACE>
<EXPIRY>2020-12-15</EXPIRY>
</PERSON_DATA>
<CARD_TYPE>idcard</CARD_TYPE>
</RESPONSE_DATA>
</HUMAN_VERIFICATION>
I prefer using Linq to Xml.
var results = doc.Descendants("PERSON_DATA") // Flatten the hierarchy and look for PERSON_DATA
.Select(x=> new
{
NAME = (string)x.Element("NAME"),
DATE_OF_BIRTH = (string)x.Element("DATE_OF_BIRTH"),
BIRTH_PLACE = (string)x.Element("BIRTH_PLACE"),
EXPIRY = (string)x.Element("EXPIRY"),
});
Check the Demo
You can try this code it may be helpful for you.
XmlDocument newdoc = new XmlDocument();
newdoc.InnerXml = " <?xml version=\"1.0\" encoding=\"utf-16\"?><HUMAN_VERIFICATION><RESPONSE_DATA><RESPONSE_STATUS><ERR>100</ERROR><MESSAGE>successful</MESSAGE></RESPONSE_STATUS><CONTACT_NUMBER>3120202456011</ CONTACT _NUMBER><PERSON_DATA><NAME>Alex</NAME><DATE_OF_BIRTH>10-9-1982</DATE_OF_BIRTH><BIRTH_PLACE>Washington</BIRTH_PLACE><EXPIRY>2020-12-15</EXPIRY></PERSON_DATA><CARD_TYPE>idcard</CARD_TYPE></RESPONSE_DATA></HUMAN_VERIFICATION>";
var selectnode = "HUMAN_VERIFICATION/RESPONSE_DATA/PERSON_DATA";
var nodes = newdoc.SelectNodes(selectnode);
foreach (XmlNode nod in nodes)
{
string name = nod["NAME" ].InnerText;
string dob = nod["DATE_OF_BIRTH"].InnerText;
string place = nod["BIRTH_PLACE" ].InnerText;
string expiry = nod["EXPIRY" ].InnerText;
Console.WriteLine("Person: {0} {1} {2} {3}", name, dob, place, expiry);
}
It's really easy and intuitive with System.Xml.Linq.
var xml = "<?xml version=\"1.0\" encoding=\"utf-16\"?>\r\n<HUMAN_VERIFICATION xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">\r\n <RESPONSE_DATA>\r\n <RESPONSE_STATUS>\r\n <ERROR>100</ERROR>\r\n <MESSAGE>successful</MESSAGE>\r\n </RESPONSE_STATUS>\r\n <CONTACT_NUMBER>3120202456011</CONTACT_NUMBER>\r\n <PERSON_DATA>\r\n <NAME>Alex</NAME>\r\n <DATE_OF_BIRTH>10-9-1982</DATE_OF_BIRTH>\r\n <BIRTH_PLACE>Washington</BIRTH_PLACE>\r\n <EXPIRY>2020-12-15</EXPIRY>\r\n </PERSON_DATA>\r\n <CARD_TYPE>idcard</CARD_TYPE>\r\n </RESPONSE_DATA>\r\n</HUMAN_VERIFICATION>";
var document = XDocument.Parse(xml);
var name = document.Element("HUMAN_VERIFICATION").Element("RESPONSE_DATA").Element("PERSON_DATA").Element("NAME").Value;
OR
var personData = document.Element("HUMAN_VERIFICATION").Element("RESPONSE_DATA").Element("PERSON_DATA").Elements().ToDictionary(e => e.Name.ToString(), e => e.Value);

I am trying to read XML using LINQ. Previously I use XMLDocument to read but it gives an error and someone on StackOverflow encourage me to use LINQ.
Below is the code i previously used for the XMLDocument
string soapmessage = #"<?xml version=""1.0"" encoding=""UTF - 8""?>" + "\n" + response.Content;
XmlDocument xml = new XmlDocument();
xml.LoadXml(soapmessage); //loading soap message as string
XmlNamespaceManager manager = new XmlNamespaceManager(xml.NameTable);
manager.AddNamespace("d", "http://tempuri.org/");
manager.AddNamespace("bhr", "http://52.187.127.196:5000/api/gsowebservice.asmx");
XmlNodeList xnList = xml.SelectNodes("//bhr:FourMonthsAhead1Response", manager);
int nodes = xnList.Count;
string Status = xnList[0]["FourMonthsAhead1Result"]["PlantForecastIntervals"]["PlantForecastIntervalNode"]["IntervalStartTime"].InnerText;
Console.WriteLine(Status);
Console.ReadLine();
I am trying to get the <IntervalStartTime> from the first <PlantForecastIntervalNode> into a datetime variable;
Below attaced the XML im trying read:
Below is some of the XML code. I can't paste it here because the code is 2322 lines long so I shortened the code to this.
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Update
After exploring other threads on StackOverflow I come up with this line below but receive another error of System.UriFormatException: 'Invalid URI: The Uri string is too long.':
XDocument xdoc = XDocument.Load(soapmessage);
var ids = xdoc.Element("FourMonthsAhead1Result")
.Elements("PlantForecastIntervals")
.Elements("<PlantForecastIntervalNode>")
.Select(item => item.Element("IntervalStartTime").Value);
Console.WriteLine(ids);
Try this using LINQ
var response = File.ReadAllText("XMLFile1.xml");
var xe = XElement.Parse(response);
XNamespace ns = "http://base.datacontract";
var obj = xe.Descendants(ns + "PlantForecastIntervals")
.Descendants(ns + "PlantForecastIntervalNode")
.Select(x => x.Element(ns + "IntervalStartTime").Value);
Console.WriteLine(obj);
Look at below solution,
var xmlRead = File.ReadAllText(#"XMLFile1.xml"); /// Add your xml file path
var xElement = XElement.Parse(xmlRead);
XNamespace xNamespace = "http://base.datacontract";
var obj = xElement.Descendants(xNamespace + "PlantForecastIntervals")
.Descendants(xNamespace + "PlantForecastIntervalNode")
.Select(x => x.Element(xNamespace + "IntervalStartTime").Value);
string[] dateTime = obj.ToArray();
foreach (string x in dateTime)
{
Console.WriteLine(x.ToString()); /// it will print time from all IntervalStartTime tags
}
I have a xml file:
<?xml version="1.0" encoding="utf-8"?>
<ApplicationConfiguration xmlns="http://test.org/SDK/Configuration.xsd">
<ApplicationName>
<ApplicationUri>123</ApplicationUri>
<ApplicationUri>456</ApplicationUri>
</ApplicationName>
</ApplicationConfiguration>
What I want is set the value of ApplicationUri from 456 to 789 in C# code.
I wrote this code:
string docaddress = "testfile.xml";
XDocument doc = XDocument.Load(docaddress);
doc.Element("ApplicationConfiguration")
.Elements("ApplicationName").FirstOrDefault()
.SetElementValue("ApplicationUri", "789");
doc.Save(docaddress);
The problems are:
There is no error while running. I think the element ApplicationConfiguration is not correct. But when I delete the line xmlns=... from the xml file, it runs normally
The value 789 is replaced with 123, but not 456 as I want (same element name)
Can you tell me how to fix those problems?
Hello and welcome to Stack Overflow!
The xmlns attribute on the ApplicationConfiguration element makes that the root.
So you get the root first. Then you replace the values of each descendant, selecting locally by name with the element name you want. something like this:
string docaddress = "C:\\temp\\testfile.xml";
XDocument doc = XDocument.Load(docaddress);
var root = doc.Root;
var descendants = root.Descendants();
var these = root.Descendants().Where(p => p.Name.LocalName == "ApplicationUri");
foreach (var elem in these)
{
elem.Value = "789";
}
doc.Save(docaddress);
I added namespace to your code :
string docaddress = "testfile.xml";
XDocument doc = XDocument.Load(docaddress);
XNamespace ns = doc.Root.GetDefaultNamespace();
doc.Element(ns + "ApplicationConfiguration")
.Elements(ns + "ApplicationName").FirstOrDefault()
.SetElementValue(ns + "ApplicationUri", "789");
doc.Save(docaddress);
IMHO, here is an easiest method.
It is taking care of the XML default namespace.
No loops. Set based approach.
c#
void Main()
{
const string fileName = #"e:\temp\hala.xml";
const string searchFor = "456";
const string replaceWith = "789";
XDocument doc = XDocument.Load(fileName);
XNamespace ns = doc.Root.GetDefaultNamespace();
// step #1: find element based on the search value
XElement xmlFragment = doc.Descendants(ns + "ApplicationUri")
.Where(d => d.Value.Equals(searchFor)).FirstOrDefault();
// step #2: if found, set its value
if(xmlFragment != null)
xmlFragment.SetValue(replaceWith);
doc.Save(fileName);
}
I got an XML response as:

</Table>
</data>
I am saving this XML response in the following string:
string response;
I want to split the string response and get values of some tags (EX:-USERNAME, STRID_FK, MERID_FK), to save it in other strings for further usage.
Please help me with this ..
XmlDocument xml = new XmlDocument();
xml.LoadXml(myXmlString);
XmlNodeList xnList = xml.SelectNodes("/data/Table");
foreach (XmlNode xn in xnList)
{
string USERNAME= xn["USERNAME"].InnerText;
string STRID_FK= xn["STRID_FK"].InnerText;
string MERID_FK= xn["MERID_FK"].InnerText;
Console.WriteLine("Name: {0, {1}, {2}", USERNAME, STRID_FK,MERID_FK);
}
or if try directly to select node
xmlDoc.SelectNodes("/data/Table/USERNAME") or
XmlNodeList nodes= doc.GetElementsByTagName("USERNAME");
Another option, this time using Linq to Xml:
var yourXml = XElement.Parse (response); // Parse the response
// Look up specific values by name:
var username = yourXml.Descendants().First(node => node.Name == "USERNAME").Value;
Yet another option is to put all the data from <Table>...</Table> into a dictionary for easy lookup later:
var dict = yourXml.Descendants()
.Where(node => node.Name == "Table")
.Descendants()
.ToDictionary(node => node.Name.ToString(), node => node.Value);
// Look up value using "USERNAME" as key:
var exampleUsername = dict["USERNAME"];
I have the below XML, and I am trying to write values to a CSV file. I am however not sure how to proceed further, with everything I've tried throwing errors. The below returns:"Expression must evaluate to a node-set". Any assistance is appreciated.
XML:
<?xml version="1.0" encoding="UTF-8"?>

C#:
xpathDoc = HttpHelper.HttpStream(xmlReq, sessionid);
XPathNavigator nav = xpathDoc.CreateNavigator();
XPathNodeIterator xmlIterator = nav.Select("/Envelope/Body/RESULT/");
var csv = new StringBuilder();
filePath = "C:\Campaigns.csv";
foreach (XPathNavigator node in xmlIterator)
{
string MailingId = node.SelectSingleNode("MailingId").Value;
string ReportId = node.SelectSingleNode("ReportId").Value;
string ScheduledTS = node.SelectSingleNode("ScheduledTS").Value;
string MailingName = node.SelectSingleNode("MailingName").Value;
string newLine = string.Format("{0},{1},{2},{3},{4}", MailingId, ReportId, ScheduledTS, MailingName, Environment.NewLine);
csv.Append(newLine);
}
File.WriteAllText(filePath, csv.ToString());
Well, you can try following approach:
foreach (XPathNavigator node in nav.Select("/Envelope/Body/RESULT/Mailing"))
{
string MailingId = node.SelectSingleNode("./MailingId").Value;
// and so on
Note: it should be exactly Mailing not RESULT as in your query, and should not ends with /
Change XPathNavigator node in nav.Select("/Envelope/Body/RESULT/") to XPathNavigator node in nav.Select("/Envelope/Body/RESULT/Mailing") and then use e.g. string MailingId = node.SelectSingleNode("MailingId").Value;.
Here is the XML sample:
<?xml version="1.0" ?>
<XMLScreen xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<CX>80</CX>
<CY>24</CY>
<Formatted>true</Formatted>
<Field>
<Location position="1" left="1" top="0" length="69" />
<Attributes Base="226" Protected="false" FieldType="High" />
*SDC SCHEDULING CATEGORY UPDATE
</Field>
</XMLScreen>
I want to retrive the Inner text of each field based on its Location position.
What I have so far is:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(myEm.CurrentScreenXML.GetXMLText());
XmlNodeList fields = xmlDoc.GetElementsByTagName("Field");
MessageBox.Show("Field spot: " + i + " Contains: " + fields[i].InnerText);
And I want to be able to just extract the inner text of the field by passing in a number of the location position. So if I say foo[i] I want to be able to get the innertext
*SDC SCHEDULING CATEGORY UPDATE
You should use a xpath search query :
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xml);
int nodeId = 4;
XmlNode node = xmlDoc.SelectSingleNode(String.Format(#"//Location[#position='{0}']", nodeId));
if (node != null)
{
String field = node.ParentNode.InnerText;
}
Something like that, with XDocument instead of XmlDocument (well, if you're not in .net 3.5 or higher, we'll have a problem).
private string GetTextByLocationId(XDocument document, int id)
{
var field = document.Descendants("Field").FirstOrDefault(m => m.Element("Location").Attribute("position").Value == id.ToString());
if (field == null) return null;
return field.Value;
}
and usage
var xDocument = XDocument.Load(<pathToXmlFile or XmlReader or string or ...>);
var result = GetTextByLocationId(xDocument, 1);
EDIT
or if you want a dictionary with :key = position / value = text
private static Dictionary<int, string> ParseLocationAndText(XDocument document)
{
var fields = document.Descendants("Field");
return fields.ToDictionary(
f => Convert.ToInt32(f.Element("Location").Attribute("position").Value),
f => f.Value);
}
Try,
XElement root = XElement.Parse(myEm.CurrentScreenXML.GetXMLText());
XElement field = root.XPathSelectElement(
string.Format("Field[Location/#position='{0}']", 1));
string text = field.Value;
You will need to use the following using to use XPath with XElements.
using System.Xml.XPath;
