Question

xmlserializer not correctly deserializing schema with import

Answer 1

A:

There's a typo in your parentschema.xsd. You're closing the <xs:element> tag prematurely for the body tag:

<xs:element name="body" type="mc:body" abstract="true"/>

You also define the body as abstract which I think is a mistake (if I'm reading the XML properly).

The whole definition (based on your XML) should look something like:

<xs:element name="body" type="mc:body" abstract="true">
    <xs:complexType>
        <xs:attribute name="id" type="xs:ID" use="required"/>
        <xs:sequence>
            <xs:element type="Foo" type="xs:anyURI" />
        </xs:sequence>
    </xs:complexType>
</xs:element>

I followed the same steps as you, and it looks like your schema and the XML file that you're deserializing are not matching. Here's what I did:

static void Main(string[] args)
{
    var xs = new XmlSerializer(typeof(toplevel));

    // test saving to xml first...
    var tl = new toplevel();
    tl.toplevel_header = new toplevel_header();
    tl.toplevel_header.name = "MyName";

    tl.body = new body();
    tl.body.id = "body id...";

    // output to console first...
    var cw = Console.OpenStandardOutput();
    xs.Serialize(cw, tl);
    Console.WriteLine();
    Console.WriteLine();

    // save to file...
    var fw = File.CreateText("test.xml");
    xs.Serialize(fw, tl);
    fw.Close();

    // read file...
    var fr = File.Open("test.xml", FileMode.Open, FileAccess.Read);
    var obj = xs.Deserialize(fr);
    var fooBar = (toplevel)obj;

    Console.WriteLine(fooBar.toplevel_header.name);
    Console.WriteLine(fooBar.body.id);
    Console.ReadLine();
}

The XML that the serializer generated was this:

<?xml version="1.0" encoding="utf-8"?>
<toplevel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns="myschema:common">
  <toplevel_header>
    <name>MyName</name>
  </toplevel_header>
  <body id="body id..." />
</toplevel>

The XML clearly does not match the input XML file you are using... Hopefully this helps you along your way!

A:

Looking at your sample xml I noticed a inconsistency which is the reason why the XmlSerializer is not coming up with what you expect:

<toplevel version="2.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:xlink="http://www.w3.org/1999/xlink"
 ***xmlns="myschema:common"***
 xsi:schemaLocation="myschema:common  http://www.myuri.org/parentschema.xsd"&gt;
    <toplevel_header>
        <name>MyName</name>
    </toplevel_header>
    <body id="body_1"
            ***xmlns="http://www.myuri.org/schema"***
            ***xmlns:mc="myschema:common"***
            xsi:schemaLocation="http://www.myuri.org/myschema http://www.myuri.org/myschema.xsd"&gt;
        <Foo href="http://www.google.com"&gt;
        </Foo>
    </body>
</toplevel>

In your toplevel element you are defining xmlns="myschema:common", and yet in your body element you are defining xmlns="http://www.myuri.org/schema" and the next line is xmlns:mc="myschema:common". This means that the Foo element inside of the body is under a different namespace and the XmlSerializer will not find the element. When I deleted the xmlns declaration in the body element and changed the xmlns:mc declaration to xmlns, like so:

<?xml version="1.0" encoding="UTF-8"?>
<toplevel version="2.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:xlink="http://www.w3.org/1999/xlink"
 xmlns="myschema:common"
 xsi:schemaLocation="myschema:common  http://www.myuri.org/parentschema.xsd"&gt;
    <toplevel_header>
        <name>MyName</name>
    </toplevel_header>
    <body id="body_1"
            xmlns="myschema:common"
            xsi:schemaLocation="http://www.myuri.org/myschema http://www.myuri.org/myschema.xsd"&gt;
        <Foo href="http://www.google.com"&gt;
        </Foo>
    </body>
</toplevel>

Having adjusted the sample xml as indicated the XmlSerializer created the toplevel object with a non-null body inside of it.
