PBDOM : Exporting to XML file gives a single line

Question

I've been starting developing with PowerBuilder 12.5 a few weeks ago. I had to write some XML files, so I got familiar with the PBDOM library.
I can build a lot of different things, it's very nice, but one thing still bothers me :
In the output file, the whole XML is written on a single line.
I use the SaveDocument function.
For example, here is some code :
PBDOM_Document doc
PBDOM_Element noderoot, node1, node11, node12
doc = CREATE PBDOM_Document
doc.NewDocument("NodeRoot")
noderoot = doc.GetRootElement()
node1 = CREATE PBDOM_Element
node1.SetName("Node1")
noderoot.AddContent(node1)
node1.SetAttribute("Attr", "AttrValue")
node11 = CREATE PBDOM_Element
node11.SetName("Node11")
node11.AddContent("Here is a value")
node1.AddContent(node11)
node12 = CREATE PBDOM_ELEMENT
node12.SetName("Node12")
node12.AddContent("Here is another value")
node1.AddContent(node12)
doc.SaveDocument("myDoc.xml")
Here is the result when I open it with notepad++
<NodeRoot><Node1 Attr="AttrValue"><Node11>Here is a value</Node11><Node12>Here is another value</Node12></Node1></NodeRoot>
Whereas I wanted :
<NodeRoot> <Node1 Attr="AttrValue"> <Node11>Here is a value</Node11> <Node12>Here is another value</Node12> </Node1> </NodeRoot>
With the notepad++ XML tools plugin, I can use the "pretty print" function to get this nice representation. But I would like my file to be formatted this way from the beginning. I noticed that the "line ending" was set to UNIX format (indicator on bottom right of the window), but I'm working on Windows. When I use the menu to convert it to Windows format (CR+LF), it changes this indicator, but the code stays on one single line.
Is there a way to tell PBDOM to export the XML file with a nice output ?
Thank you !
Notes :
- Opening the XML file with Internet Explorer or Google Chrome gives me a nice vizualisation, with indentation, line breaks...
- Adding a <?xml version="1.0" encoding="ISO-8859-1" ?> does not help (I've been doing it while exporting some more complex files, but I still get the output on one line...)

Here is a very simple powerbuilder example. It uses MSXML instead of PBDOM. See my comments for hints how to use it with PBDOM.
oleobject lole_dom, lole_root, lole_element1, lole_element11, lole_element12
oleobject lole_Writer, lole_saxreader
string ls_result
// build DOM (you don't need this if you use PBDOM)
lole_dom = create oleobject
lole_dom.ConnectToNewObject ("Msxml2.DOMDocument")
lole_root = lole_dom.CreateElement ("NodeRoot")
lole_dom.documentElement = lole_root
lole_element1 = lole_dom.CreateElement("Node1")
lole_root.AppendChild(lole_element1)
lole_element1.SetAttribute("Attr", "AttrValue")
lole_element11 = lole_dom.CreateElement("Node11")
lole_element11.AppendChild (lole_dom.CreateTextNode("Here is a value"))
lole_element1.AppendChild(lole_element11)
lole_element12 = lole_dom.CreateElement("Node12")
lole_element12.AppendChild (lole_dom.CreateTextNode("Here is another value"))
lole_element1.AppendChild(lole_element12)
// this saves the DOM without formatting
//lole_dom.save ("d:\testxml.xml")
// this part is for formating
lole_Writer = create oleobject
lole_saxreader = create oleobject
lole_Writer.ConnectToNewObject ("MSXML2.MXXMLWriter")
lole_saxreader.ConnectToNewObject ("MSXML2.SAXXMLReader")
lole_Writer.omitXMLDeclaration = True
lole_Writer.indent = True
lole_saxreader.contentHandler = lole_Writer
// instead of DOM you can also put a XML string to parser: lole_saxreader.parse ("<node>...</node>")
// so you can also use the PBDOM output directly
lole_saxreader.parse (lole_dom)
// here is your formatted output
ls_Result = lole_Writer.output
MessageBox ("", ls_result)
lole_writer.Disconnectobject( )
lole_saxreader.Disconnectobject( )
lole_dom.Disconnectobject( )
DESTROY lole_writer
DESTROY lole_saxreader
DESTROY lole_dom
