How to deserialize/serialize Microlife's xml in c#
Question
When I need to handle a specific xml file, I usually generate c# classes using xsd2code. But now I have a strange xml file used by Microlife's Blood Pressure Analyser. The xml file contains its schema inside as an extra first element, like this example
<?xml version="1.0" standalone="yes"?>

I can handle this only without the xsd:schema part. How to serialize/deserialize the complete xml file?

I am able to load a NewDataSet, and corresponding Patient / Measurements etc from your sample file using this snippet.
void Main()
{
var path = @"... path to your sample xml";
// you could skip this step, and deserialize directly from a file stream.
var xml = XElement.Load(path);
var nds = new XmlSerializer(typeof(NewDataSet)).Deserialize(xml.CreateReader());
nds.Dump();
}
public class NewDataSet
{
public Patient Patient { get; set; }
[XmlElement("MeasureRec")]
public MeasureRec[] Recs { get; set; }
[XmlElement("Comment")]
public Comment[] Comment { get; set; }
}
public class MeasureRec
{
public int Pulse { get; set; }
}
public class Comment
{
[XmlElement("Comment")]
public string Text { get; set; }
}
public class Patient
{
public string FamilyName { get; set; }
public string GivenNames { get; set; }
}
Gives a NewDataSet instance, with the family name, and given name populated in Patient , MeasureRec , and some Comment (s).

Based on Jim's answer and comments, I recognised, that my problem at deserialize was that xsd2code generates an Order XmlElementAttribute for each element. If I remove these attributes, the deserialization works fine for this xml. It also works (without changing anything in the generated code) if I remove the schema element from the xml. Unfortunately, I cannot omit this element by writing an xml for the BP Analyzer, because it can import the xml file only if it this element is present. So, my final solution is keeping the original code generated by xsd2code (from the given schema) and adding the following partial class that removes and memorizes the schema element at reading, and inserts it back at writing.
partial class NewDataSet
{
[XmlIgnore]
public XNode schema { get; set; }
public static NewDataSet Read(string path)
{
var xml = XElement.Load(path);
var schema = xml.FirstNode;
xml.FirstNode.Remove();
string xmlstring = xml.ToString();
var ret = NewDataSet.Deserialize(xmlstring);
ret.schema = schema;
return ret;
}
public void Write(string path)
{
var XmlString = this.Serialize();
var xml = XElement.Parse(XmlString);
xml.AddFirst(this.schema);
xml.Save(path);
}
}
The Serialize and Deserialize methods are written by xsd2code.
