Hi....................

Am working with ASP.NET Usin VB for a Music Project...

I have the list of songs for a movie in a datagrid with a checkbox.If check box is checked then that song shoul play when PlaySelected button is clicked.

Here the player is taking the xml file i.e when we click on the PlaySelected button a xml file should created...

like

<playlist>

<element url="skins/skin1/songs/Movie/Aata/aata.mp3" />

<element url="'/>

</playlist>

I have the following code....

Private Sub playSelected()
Dim check As Boolean

Dim Music As New MusicMachine
Dim strname As String = Music.GetMusicFileId

Dim item As DataGridItemDim writer As New XmlTextWriter(Server.MapPath("~\XML\") & strname & ".xml", Encoding.UTF8)
writer.WriteStartDocument()

writer.WriteStartElement("playlist")

Try

For Each item In FileSystemGrid.Items Dim chkBx As CheckBox = CType(item.Cells(0).FindControl("deletethis"), CheckBox)
If chkBx.Checked Then

check = True

writer.WriteElementString("element", "")

writer.WriteAttributeString("url", "Skins\skin1\Songs\" & Request.QueryString("Type") & "\" & Request.QueryString("Name") & "\" & item.Cells(2).Text)

Page.RegisterStartupScript("Popup", "<script> popUp('player.aspx');</script>")

End If

Next

If check = False Then

Response.Write("<script language=""javascript"">alert('Select at least One Song!');</script>")

End If

writer.WriteEndElement()

writer.WriteEndDocument()

writer.Close()

Catch ex As Exception
Response.Write(ex.Message)

Response.End()

End Try

End Sub



................................

But the above code is not working,It is displaying a error like

Token StartAttribute in state Content would result in an invalid XML document.



Please help me out

Thanks in Advance

Once the call the WriteElementString has completed you are not in the element tag anymore, so you are adding the attribute to nothing.

Just do a WriteStartElement("element") before the WriteAttributeString() and then a WriteEndElement() after it.
