I want to generate below code snippet into xml with c#:
<?xml version="1.0" encoding="utf-8" ?>
<PrincetonStorageRequest
xmlns="http://munichre.com/eai/dss/pct/v1.0"
requestId="RequestOut_MAG_Test_02"
timestampUtc="2015-02-19T09:25:30.7138903Z">
<StorageItems>
and my code is :
XmlWriter writer = XmlWriter.Create(fileName);
writer.WriteStartDocument(true);
writer.WriteStartElement("PrincetonStorageRequest");
writer.WriteAttributeString("xmlns","http://example.com/abc/dss/pct/v1.0");
writer.WriteAttributeString("requestId",name);
writer.WriteAttributeString("timestampUtc","2015-02-19T09:25:30.7138903Z");
writer.WriteStartElement("StorageItems");
But I am getting
"The prefix " cannot be redefined from " to within the same start element tag.
From your XML and the error, I believe it's because you are adding a default namespace after adding an element with no namespace declaration, so you're effectively creating an element and then changing its namespace.
Try the following code - it stops the error when I test it locally just for the XML I think you're trying to get:
XmlWriter writer = XmlWriter.Create(fileName);
writer.WriteStartDocument(true);
writer.WriteStartElement("PrincetonStorageRequest", "http://example.com/abc/dss/pct/v1.0");
writer.WriteAttributeString("xmlns", "http://example.com/abc/dss/pct/v1.0");
writer.WriteAttributeString("requestId", name);
writer.WriteAttributeString("timestampUtc", "2015-02-19T09:25:30.7138903Z");
writer.WriteStartElement("StorageItems");
So when I create the PrincetonStorageRequest element I am specifying a namespace URI.
Edit: Just to check, this is the XML that gets created but I did have to add the code to write the end elements:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<PrincetonStorageRequest xmlns="http://example.com/abc/dss/pct/v1.0" requestId="RequestOut_MAG_Test_02" timestampUtc="2015-02-19T09:25:30.7138903Z">
<StorageItems/>

I am working on deserializing XML file where a same class has different namespaces. I am getting error while The specified type was not recognized. Here is a snippet from the XML I am trying to parse
<BookingHistory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns3="dbpnr" xsi:type="ns3:SegmentHistory" Segment="ID13" eventDate="2014-04-03" eventTime="05:29:00" actionType="Change"/>
<BookingHistory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns3="dbpnr" xsi:type="ns3:SsrHistory" eventDate="2014-04-03" eventTime="14:06:00" actionType="Add">
<BookingHistory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns3="dbpnr" xsi:type="ns3:RemarkHistory" eventDate="2014-04-03" eventTime="15:02:00" actionType="Add">
Here is the sample XML
https://drive.google.com/file/d/1RDOAGa2TECSIauSHkdYTuSNuTWx5GVb8/view
Any suggestions would be highly appreciated.
Following is the XML format:
<?xml version="1.0" encoding="UTF-8"?>
<package version="2.0" unique-identifier="isbn0000000000000" xmlns="http://www.idpf.org/2007/opf">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
<dc:title>Eltern Family</dc:title>
<dc:creator></dc:creator>
<dc:publisher></dc:publisher>
<dc:rights></dc:rights>
<dc:identifier id="isbn0000000000000">0000000000000</dc:identifier>
<dc:language>de</dc:language>
<dc:date opf:event="publication">2019-02-11</dc:date>
</metadata>
</package>
Here I got the default Namespace by XDocument.Root.GetDefaultNamespace();. But as you can see, there are multiple namespaces in the <metadata> XML node. The problem is that, they are variable i.e., each XML may have different values, so I cannot declare a variable with one fixed value.
How do I get the namespaces, so that I can add values to the descendant elements?
Please help.

If, as you say, you want to set the content of dc:rights, then you need to get hold of that element.
You can do this by name - the 'qualified name' is made of of the namespace and a local name. The namespace prefix dc is not actually important in and of itself, it's just used as a shorthand to refer to the namespace within the document.
Assuming you have parsed this XML to an XDocument called doc:
XNamespace dc = "http://purl.org/dc/elements/1.1/"
var rights = doc.Descendants(dc + "rights").Single();
rights.Value = "text";
I am quite new to xml-parsing.
Following very basic tutorials I try to parse the following xml returned by a CalDav server:
<?xml version="1.0" encoding="utf-8" ?>
<multistatus xmlns="DAV:">
<response>
<href>/caldav.php/icalendar.ics</href>
<propstat>
<prop>
<getetag>"xxxx-xxxx-xxxx"</getetag>
</prop>
<status>HTTP/1.1 200 OK</status>
</propstat>
</response>
<sync-token>data:,20</sync-token>
</multistatus>
Now I want to find my "response" descendants as follows:
Doc = XDocument.Parse(response);
foreach (var node in xDoc.Root.Descendants("response")) {
// process node
}
No descendant is found. Am I missing something here? My root is indeed a "multistatus" element, it says it has elements, but it doesn't seem as they can be found by name...
Any help would be much appreciated!
Your response element is actually in a namespace, due to this attribute in the root node:
xmlns="DAV:"
That sets the default namespace for that element and its descendants.
So you need to search for elements in that namespace too. Fortunately, LINQ to XML makes that really simple:
XNamespace ns = "DAV:";
foreach (var node in xDoc.Root.Descendants(ns + "response"))
{
...
}
I have generated a set of classes using xsd.exe and created an XML document from the resulting generated code. I would now like to validate the serialized class instance against the original xsd.
My XML is like this:
<?xml version="1.0" encoding="UTF-8"?>
<MyRoot xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
-- rest of XML document here
</MyRoot>
My XSD is like this:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="MyRoot" type="MyRootType"/>
-- MyRootType definition and rest of XSD
</xs:schema>
When I try to validate the XML using a XmlReader, I get the following error:
"The 'MyRoot' element is not declared."
What could be wrong?
In your MyRoot element, you need to add the location of the XSD. I would also recommend defining the namespace (unless you have good reason not to).
<api:MyRoot xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:api='http://www.myserver.com/schema'
xsi:schemaLocation='http://www.myserver.com/schema http://www.myserver.com/schema/websuiterecord.xsd'>
</api:MyRoot>
This way, the validation tool knows where to find your XSD to validate your XML against.
The approach was correct, but the XSD was not infact being read. I corrected this and it worked as expected.

XmlSerializer: remove unnecessary xsi and xsd namespaces
I'm generating some XML using XMLSerializer and a class marked up with attributes. This XML is sent to a REST web service.
It generates the following XML:
<?xml version="1.0" encoding="utf-8"?>
<person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<first-name>API</first-name>
<last-name>TestPersonDeleteMe</last-name>
<title>Delete me</title>
</person>
All would be well, except the web service I'm using doesn't understand the schema stuff and throws a 500 error.
Is there a way to stop XmlSerializer adding 'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"' to the person tag?
if you use custom serializer try this
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
then add namespaces object to your serializer.
