Saving XML???

Hi guys,
I'm new to this XML stuff and something is really bugging me...
If I save my XML using the MS implementation of the DOM and then open the resulting file in notepad, the XML is all written on one line .... ie unformatted! Is there anyway to format it to make it more readable? I notice that if you read in a formatted file and then write it back out it gets written in a formatted form.

Any ideas???

Cheers

I have never found a totally satisfactory solution, and I have asked the same question on this and other forums. In one respect it doesn't matter because if you open the file using a browser or XML Spy, it will appear properly formatted, but I know it's nice to be able to look at it in Word, Notepad, etc.

I wrote the following routine that at least breaks up the lines. What I am posting here is a version with some non-applicable code removed and I haven't tested it, so if it doesn't work please let me know. Also I would be very interested in any better solution.

VB Code:

Private Declare Function GetTempPath Lib "kernel32" _
         Alias "GetTempPathA" (ByVal nBufferLength As Long, _
         ByVal lpBuffer As String) As Long
 
Private Declare Function GetTempFileName Lib "kernel32" _
         Alias "GetTempFileNameA" (ByVal lpszPath As String, _
         ByVal lpPrefixString As String, ByVal wUnique As Long, _
         ByVal lpTempFileName As String) As Long

Thanks for that. It seems rediculous that the object model doesn't allow for this though.....does anyone know of a simpler way???

I just had a thought. The first time you split a line using my code, you could do this

strOutputLine = Space(4) & Left$(strLine, intPos)

then if you could keep track somehow of how many indents you had previously made you could do something like

strOutputLine = Space(8) & Left$(strLine, intPos)
