I have a xml file that looks like this :
<?xml version="1.0" encoding="utf-8"?>
<config>
<node id="1" />
</config>
Now I try to deserialize it, but always get the error :
<config xmlns=''> was not expected
Anyone how to fix this ? I dont have any control over the xml.
Thanx
Why not just load it in as a DOM (e.g. using XmlDocument or XDocument) and extract the data yourself? Assuming it wasn't saved with XmlSerializer, there's no point in trying to deserialize it that way.
EDIT: It would help if you'd give us some background here. If this isn't a valid XmlSerializer output, what is it? Was it originally a valid file, but something has stripped out the namespaces? If so, what else has it done?
You may well be able to get away with just reapplying the namespace everywhere yourself (to every element) although that may be annoying do. Currently we can't really tell though.

i need to serialize a dataset in c# to xml for sending the data to a webservice. I cannot change the webservice so my code has to be changed to fit the requirements of the webservice.
I use dataset.WriteXmlSchema(stream) to write the schema and add dataset.WriteXml(stream) to add the data itself.
The result now looks like following:
<?xml version='1.0'?>
<xs:schema id='DocumentElement' xmlns='' xmlns:xs='http://www.w3.org/2001/XMLSchema' ...
Is there a chance to get rid of the <?xml version='1.0'?> declaration?
I need to encapsulate the XML result of the dataset into other xml data and the xml declation breaks the data i need to send. I didn't want to start with fuzzy string handling and i thought there must be something more straight forward.
Thanks

There seems no way to omit the xml declaration. I've implemented some code to remove the first line of the xml. Not nice but it works.
I am trying to use XDocument.Parse(string s) to parse some XML that is being returned from a REST based API. After the XML is parsed, it creates a new XDocument, but the document doesn't contain the properly parsed XML nodes. The name of the first node is the correct node name, but the value is the the concatenation of all the text from the XML, regardless of which Element is belongs to. Can anybody help me figure out what is going on?
XML

<desc>Invalid target. Device not found.</desc>
</error>
</device>
<error>Invalid SCI request. No valid targets found.</error>
</send_message>
</sci_reply>
Debug View of XDocument Object
That's the expected behavior. The Value of a an XML element is concatenation of values of all its children. If you want to actually access the XML, read something about LINQ to XML or classes in the System.Xml.Linq namespace.
Thats just the debugger being nice.
The root is being displayed with all of its children.
We have an odd problem, we are tranforming a pretty complicated XML file using several XSLT files, this isnt the issue.
The issue is that IF the XML file is attached to the schema, the transform doesnt work, if we remove the schema declaration it begins to work ok.
Any clues what the problem would be?
Here is the schema declation
<xs:schema id="play"
targetNamespace="highway"
elementFormDefault="qualified"
xmlns="highway"
xmlns:mstns="highway"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
And we are simply using the following code to link it (Visual Studio Intellisense then kicks in)
<helloElement name="hello" xmlns="highway">
I appreciate this isnt much to go on, not sure what to offer in terms of symptoms, let me know if you need any info.
Many thanks!
The problem is not the schema, the problem is the namespace declaration xmlns="highway" which your stylesheet(s) need to take into account with e.g.
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:hw="highway"
version="1.0">
<xsl:template match="hw:helloElement">
...
</xsl:template>
</xsl:stylesheet>
and so on, anywhere you match or select an element you need to use a prefix.
When you add the schema declaration, you are adding a default namespace to your XML document (xmlns="highway") which wasn't there before. This will then affect the interpretation of element references and XPATHs in the XSLT, because all your elements are now no longer <someElement>, they are <highway:someElement>.

I am creating an XML file in C# using a XSD Schema of an InfoPath form.
When I save the IP form without using the code, I get an XML file with the following header:
<?xml version="1.0" encoding="UTF-8"?>
<?mso-infoPathSolution solutionVersion="1.0.0.113" productVersion="14.0.0" PIVersion="1.0.0.0" href="file:///\\Hmfp\mcs-shared\PMU\PMU-shared\Tests\QF%207.5%20PMU%20Project%20Outline%20Form%20F1.0.xsn" name="urn:schemas-microsoft-com:office:infopath:QF-7-5-PMU-Project-Outline-Form-F1-0:-myXSD-2010-07-22T07-48-32" ?>
<?mso-application progid="InfoPath.Document"?>
<my:myFields...
And this file is recognized by InfoPath and uses the correct XSD, thus displaying the XML data in the correct form.
But when I use the code, I get this:
<?xml version="1.0"?>
<myFields...
And this is not recognized nor opened directly by InfoPath; so I would like to insert the two tags in order to keep that functionality, so that the users do not see the difference.
My line of thought is to modify the XML file after it has already been created, saved and closed.
It would be very nice if you could help :D. Thanks in advance..
EDIT: I've finally been able to achieve what I wanted. I made use of both MainMa's and dahlbyk's answers and came up with something that works:
I let the file get saved like before
I created an XmlReader object from the file
I loaded the XmlReader into an XmlDocument object
I created an XmlProcessingInstruction object using XmlDocument.CreateProcessingInstruction
I inserted that PI in the XmlDoc using xmlDoc.InsertAfter(thePI, XmlDoc.FirstChild)
I then created a second PI object
Which I inserted using xmlDoc.InsertAfter(thePI, XmlDoc.FirstChild.NextSibling)
Then I saved the XmlDoc in the file, overwriting it
Anyway, your answers helped me understand many things, which made me find the answer, so thank you very much!!
I would try making an XmlWriter for your FileStream, use WriteProcessingInstruction() to add your headers, then pass the writer into the appropriate overload of Serialize() to capture the rest of the output.
The first three lines of your first code sample are called XML processing instructions (PI). So if you are creating your output XML with XmlDocument, you can use XmlDocument.CreateProcessingInstruction method to add the required PI.
If you are serializing into XML, you can also use XmlTextWriter.WriteProcessingInstruction just before serializing the object.
If for some reasons, you cannot do that, you can also save the file, open it and insert two PI after the first line break, but I highly discourage you to do that, since it will make your code difficult to maintain in future, and slow things down.
I just came across with a problem using XmlDocument.LoadXml.
The application was crashing, giving the following error:
"Data at the root level is invalid. Line 1, position 1"
After inspecting the XML and finding nothing wrong with it, I googled a bit and found a tip to use XmlDocument.Load instead of XmlDocument.LoadXml.
I have tried it and it works perfectly.
My question is: What is the difference between the 2 methods and what could have cause one to work and the other to fail?
XmlDocument.Load is used to load XML either from a stream, TextReader, path/URL, or XmlReader.
XmlDocument.LoadXml is used to load the XML contained within a string.
They're fundamentally different ways of loading XML, depending on where the XML is actually stored. So it sounds like you were using the wrong method for where your XML is.
Were you trying to use XmlDocument.LoadXml and passing in the name of a file? It doesn't do that - it assumes that the string you pass in is the XML. So you might use:
doc.LoadXml("<root><child /><root>");
or
doc.Load("myfile.xml");
If that doesn't help, could you show your failing and working code? There are different ways you could have changed from using LoadXml to Load...
Load() loads from a certain source, whereas LoadXml() loads directly from a string
Assuming your using XmlDocument.Load and XmlDocument.LoadXml in the right way this problem may be caused by Byte Order Mark.
This other question might be useful.
The application was crashing with the following error: "Data at the root level is invalid. Line 1, position 1"
I suspect you xml data does not have a root level:
for example:
<area id="1">
<candidate id="0">dataata</candidate>
</area>
<area id="2">
<candidate id="0">dataataa</candidate>
</area>
you need have at least one root level on top of the bottom levels.
for example:
<areas>
<area id="1">
<candidate id="0">dataata</candidate>
</area>
<area id="2">
<candidate id="0">dataataa</candidate>
</area>
</areas>
so please put one mother on the top of your level, make it grand grand mother of all children
