Deserialize XML String 1

[deulyd]

Hi,

I have an XML array stored into a string variable. I juste need to deserialize it to retrieve the array. I tried the System.Xml.Serialization.XmlSerializer object to Deserialize it but that method only takes stream, textReader or XMLReader; no string!

Please help

Thanks

Daniel

How was the XML created?

It's created by an external application that I can't manage. Here's my XML String I need to deserialize :

<?xml version="1.0" ?>
- <complexType length="5">
- <complexType length="2">
<string xml:space="preserve">Daniel</string>
<string xml:space="preserve">Bordeleau</string>
</complexType>
- <complexType length="2">
<string xml:space="preserve">Robert</string>
<string xml:space="preserve">Payant</string>
</complexType>
- <complexType length="2">
<string xml:space="preserve">Helene</string>
<string xml:space="preserve">Bock</string>
</complexType>
- <complexType length="2">
<string xml:space="preserve">Martin</string>
<string xml:space="preserve">Roy</string>
</complexType>
- <complexType length="2">
<string xml:space="preserve">Marlene</string>
<string xml:space="preserve">Duval</string>
</complexType>
</complexType>

OK, technically, this isn't deserialization. You've got a series of records in an xml string that you want to turn into a collection of objects.

Since the structure seems pretty well ordered (even if the element names sure look like they're from an XSD), I would open an XMLTextReader and start reading the file. When you get to the level where's there's data (your 2nd "complexType" element), I would pass the reader to a subroutine which would read the XML, using reader.GetString, etc, to create a person object. This object then gets added to an ArrayList. Continue to end of file.

Thanks!

But would you give me an example on how to do that, I'm really new to the .NET world. Also is it possible to read it from a string instead of a file, because My XML is stored in a string.

Ok, I've managed to find a way to make the XMLTextReader work and I can now read the data. But within parameters of the XMLTextReader I can get the values and the Elements. But how can I get the lenght of the complex type elements?

Thanks

Are you sure you need the length? It looks like it's 2 every time.

You can do something like:

If reader.HasAttributes Then
  Dim i As Integer
  For i = 0 To reader.AttributeCount - 1
     Console.WriteLine(reader(i).ToString())
  Next i
End If
