XML
Copy 
<ContentType 
    ID="0x010100C78DE4D7C0C57C43AF878D28256599CA" 
    Name="NewContentType" 
    Group="Custom Content Types" 
    Description="Create a new document." 
    Version="1" 
    xmlns="http://schemas.microsoft.com/sharepoint/soap/">
  <Folder TargetName="Forms/NewContentType" />
  <Fields>
   ...
  <DocumentTemplate TargetName="Forms/NewContentType/template.doc" />
  <XmlDocuments>
    ...
  </XmlDocuments>
</ContentType>

The content type definition is the same as would be returned by invoking the SchemaXml method.

The following example retrieves the content type definition for the specified list content type, and saves it as an XML file.

VB
Copy 
Imports System.Xml
Imports System.Web.Services.Protocols

Public Sub GetOneListContentType()
  Dim listService As New Web_Reference_Folder.Lists
  listService.Credentials = System.Net.CredentialCache.DefaultCredentials

  Dim listName As String = "listName"
  Dim contentTypeId As String = "0x010100C78DE4D7C0C57C43AF878D28256599CA002E1A80DF76000C4780E09DDFFB90076D"

  'Retrieve site content type data from Web service.
  Try
    Dim myNode As XmlNode = listService.GetListContentType(listName, contentTypeId)

    'Create XML document.
    Dim XmlDoc As New XmlDocument
    Dim d As XmlNode
    d = XmlDoc.CreateXmlDeclaration("1.0", "", "yes")
    XmlDoc.AppendChild(d)

    'Move Web service data into XML document and save.
    Dim root As XmlNode = XmlDoc.CreateElement("ContentTypes")
    root.InnerXml = myNode.OuterXml
    XmlDoc.AppendChild(root)
    XmlDoc.Save("SingleListContentType.xml")

  Catch ex As SoapException
    MessageBox.Show("Message:" + ControlChars.Lf + ex.Message & _
      ControlChars.Lf & _
    "Detail:" + ControlChars.Lf + ex.Detail.InnerText & _
      ControlChars.Lf & _
    "StackTrace:" & ControlChars.Lf + ex.StackTrace)

  Catch ex As Exception
    MessageBox.Show(ex.Message.ToString)

  End Try
End Sub
