  1. PO.Net XML Serialization based on an XSD?
    text
    copied!<p>I've been serialising and deserialising .net objects using the XmlSerializer class without problem, however we now need somebody else to look at that data to perform some analysis on it.</p> <p>In order to help with that we've produced an XSD based on our class like so: xsd.exe /t:DataClass Assembly.exe</p> <p>The start of the XSD looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"&gt; &lt;xs:element name="DataClass" nillable="true" type="DataClass" /&gt; &lt;xs:complexType name="DataClass"&gt; &lt;xs:complexContent mixed="false"&gt; &lt;xs:extension base="BaseDataClass"&gt; &lt;xs:sequence&gt; &lt;xs:element minOccurs="0" maxOccurs="1" name="StudyID" type="xs:string" /&gt; &lt;xs:element minOccurs="1" maxOccurs="1" name="Position" type="xs:int" /&gt; &lt;xs:element minOccurs="1" maxOccurs="1" name="IViewer" type="xs:string" /&gt; </code></pre> <p>The XML is produced like this (where obj is an instance of our DataClass):</p> <pre><code>Dim xs As New XmlSerializer(obj.GetType) Dim xmlTextWriter As New XmlTextWriter(memoryStream, Encoding.UTF8) xs.Serialize(xmlTextWriter, obj) </code></pre> <p>...which produces XML looking like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;DataClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt; &lt;Version&gt;SixMonthQ-E1&lt;/Version&gt; &lt;IViewer xsi:nil="true" /&gt; &lt;Language xsi:nil="true" /&gt; ... &lt;StudyID&gt;12345&lt;/StudyID&gt; </code></pre> <p>Bizarly, the XML produced does not adhere to the XSD generated from the same class. </p> <p>My question then is, is there a way of telling the XmlSerializer to serialize the object based on a given XSD? </p> <p>As an aside, I've looked at other ways of fixing this: I've tried re-generating the classes from the generated XSD - this seemed to have the same problem. I could explicitly state an ordering of elements using the XmlElement attribute, but I don't fancy doing that for 400+ public properties.</p>
