How do I access xsd value using xpath

I have the following xsd file...
<?xml version="1.0" encoding="Windows-1252"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="order">
<xs:complexType>
<xs:sequence>
<xs:element name="ordername" maxOccurs="1" minOccurs="1" type="xs:string" />
<xs:element name="articles">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="article">
<xs:complexType>
<xs:sequence>
<xs:element name="Account" maxOccurs="1" minOccurs="1">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="1|5|7|9"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="Vat" maxOccurs="1" minOccurs="1">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="1|2|3"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
I am trying to access all allowed patterns for a specific element. In this case I would like to find the allowed pattern for "Account" which should give me "1|5|7|9". Ideally I would like to be able to directly access the value, something like this...
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fileName);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
var nodeToAccess = xmlDoc.DocumentElement.SelectSingleNode("order/articles/article/Account", nsmgr);
But that does not work, can anyone please show the proper way to do this?

You can use XPath for this:
var nodeToAccess = xmlDoc.SelectSingleNode("//xs:element[#name='Account']/xs:simpleType/xs:restriction/xs:pattern", nsmgr);
if (nodeToAccess != null)
{
Console.WriteLine(nodeToAccess.Attributes["value"].Value);
}

How to create child node using named types in XML

I have the below xsd schema and I want to add the DG collection inside DGItems. So I want to know how can I achieve that.
When look at my xml at the 2nd section in that manner I want to achieve that. Just a little help needed to fix that.
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">

Need your help on this.

I have solved the issue on my own, the thing which i have done to fix my issue is are as follows : I have added the Element AI inside the Sequence node & in this way I was managed to fix my issue.
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="EmployeeData" type="EmployeeData"/>
<xs:complexType name="EmployeeData">

<xs:element name="EmployeeHeaderData" type="EmployeeHeaderData"/>
<xs:element name="AddressItems" type="AddressItems"/>
</xs:sequence>

<xs:complexType name="EmployeeHeaderData">
<xs:sequence>
<xs:element name="CompanyId" type="xs:string" />
<xs:element name="ImageID" type="xs:string" />
<xs:element name="Incident" type="xs:string" />
<xs:element name="FacilityID" type="xs:string" />
</xs:sequence>

Check XML file if it has the same structure

I need to validate another XML file. Is there a way I can check another XML file if it has the same structure as my file here?

You need an XSD file to check whether an xml is proper. If you do not have the xsd file, some tools may create xsd from xml, but you may need to modify created xsd.
This answer describes how to validate an xml file in c# against an XSD file.

You need to create xml scheme and then use XDocument.Validate method to check if the xml conform the scheme

You can create a xsd schema that possibly can look something like this. (I recommend #daryal's xml schema , but i would throw some constraints on the xml elements.)
<xs:element name="SystemSettings">
<xs:complexType>
<xs:sequence>
<xs:element name="Workstation" minOccurs="0" maxOccurs="1" />
...
</xs:sequence>
</xs:complexType>
...
Then you can use this code to perform validation
using (var xsdStream = new MemoryStream(fXmlSchema))
{
xsdStream .Position = 0;
using (var xsdReader = XmlReader.Create(xsdStream ))
{
XmlReaderSettings settings = new XmlReaderSettings();
settings.ValidationType = ValidationType.Schema;
settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
settings.Schemas.Add(XmlSchema.Read(xsdReader , [performingValidationCallback]));
using (var xmlStream = new MemoryStream(fXml))
{
using (var xmlReader = XmlReader.Create(xmlStream, settings ))
{
try
{
xmlStream .Position = 0;
while (xmlReader .Read())
{
}
}
catch (XmlException e)
{
//VALIDATIONERROR
}
}
}
}
}

Problem with deserializing a message with substitutionGroup

I have the following XML message that I deserialize with XmlSerializer.
For some reasons, deserialization of this message strips the Database section of the XML message.
I need some help in deserializing this message in its entirety.
This is a sample test XML message.
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Radars xmlns="http://mycompany.com/2008/c2s2">
<Radar>
<Identification>
<Identifier>140:141</Identifier>
<IP>10.216.1.79</IP>
<Label>Radar 1</Label>
<Model>Radar123</Model>
<Category>Civil</Category>
</Identification>
<Database>
<Radar456General>
<Identifier>203</Identifier>
<Version>8</Version>
<RadarStartStop>false</RadarStartStop>
<AntennaRotationSpeed>false</AntennaRotationSpeed>
<RadarAntennaRotation>false</RadarAntennaRotation>
<AntennaStaringPosition>0</AntennaStaringPosition>
</Radar456General>
</Database>
</Radar>
</Radars>
I am using XmlSerializer to deserialize the above message like this:
public static T Deserialize<T>(string message)
{
object obj = null;
try
{
XmlSerializer xs = new XmlSerializer(typeof(T));
StringReader reader = new StringReader(message);
XmlTextReader xmlReader = new XmlTextReader(reader);
obj = xs.Deserialize(xmlReader);
xmlReader.Close();
reader.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex);
throw ex;
}
return (T)obj;
}
Radars radars = Serializer.Deserialize<Radars>(message);
After deserializing it, I get an empty Database section (meaning radars.radar[0].Database.Length == 0).
The schema of the message is specified in a separate XSD file. I use xsd.exe to generate C# classes from it.
This is the partial content of the XSD file.

So how can I deserialize the message with Database section?

Try create the same object structure in code, serialize it and see he differences between your data and serialized date, than you'll know whats wrong.

Problem deserializing xml file

I auto generated an xsd file from the below xml and used xsd2code to get a c# class. The problem is the entire xml doesn't deserialize.
Here is how I'm attempting to deserialize:
static void Main(string[] args)
{
using (TextReader textReader = new StreamReader("config.xml"))
{
// string temp = textReader.ReadToEnd();
XmlSerializer deserializer = new XmlSerializer(typeof(project));
project p = (project)deserializer.Deserialize(textReader);
}
}
here is the actual XML:
<?xml version='1.0' encoding='UTF-8'?>
<project>
<scm class="hudson.scm.SubversionSCM">
<locations>
<hudson.scm.SubversionSCM_-ModuleLocation>
<remote>https://svn.xxx.com/test/Validation/CPS DRTest DLL/trunk</remote>
</hudson.scm.SubversionSCM_-ModuleLocation>
</locations>
<useUpdate>false</useUpdate>
<browser class="hudson.scm.browsers.FishEyeSVN">
<url>http://fisheye.xxxx.net/browse/Test/</url>
<rootModule>Test</rootModule>
</browser>
<excludedCommitMessages></excludedCommitMessages>
</scm>
<openf>Hello there</openf>
<buildWrappers/>
</project>
When I run the above, the locations node remains null.
Here is the xsd that I'm using:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

</xs:sequence>
<xs:attribute name="class" type="xs:string" />
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="class" type="xs:string" />
</xs:complexType>
</xs:element>
</xs:all>
</xs:complexType>
</xs:element>
<xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element ref="project" />
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>

Figured it out. When using xsd2code I had select options to target the 3.5 framework and include the xml attributes. It now deserializes as expected. Not sure which one did it, but works now.

According to this page '.' is not a valid XML tag name character, so you need to rename <hudson.scm.SubversionSCM_-ModuleLocation> to something without the dots.
