C# and VB.NET example code to embed a binary file into XML, and extract. Can optionally encrypt/decrypt with 128-bit AES encryption, and zip/unzip (using the .zip deflate algorithm).

Dim xml As New Chilkat.Xml()

Dim success As Boolean

xml.Tag = "test"

Dim zipContent As Boolean
zipContent = true
'  If desired, the content can be 128-bit AES encrypted:
Dim encryptContent As Boolean
encryptContent = false
Dim encryptPassword As String
encryptPassword = ""

success = xml.SetBinaryContentFromFile("chilkat.bmp",zipContent,encryptContent,encryptPassword)
If (success <> true) Then
    MsgBox(xml.LastErrorText)
    Exit Sub
End If


'  Display the XML:
TextBox1.Text = TextBox1.Text & xml.GetXml() & vbCrLf

'  Extract the binary content from XML:
Dim unzipContent As Boolean
unzipContent = true
Dim decryptContent As Boolean
decryptContent = false
Dim decryptPassword As String
decryptPassword = ""
success = xml.SaveBinaryContent("out.bmp",unzipContent,decryptContent,decryptPassword)
If (success <> true) Then
    MsgBox(xml.LastErrorText)
    Exit Sub
End If


MsgBox("Success!")
