Thanks for the help so far. tried a few things but hitting a wall on this.
I tried the code and it worked if the xml file was a string in the program. I tried the code by copying the contents of the file that I was trying to import and it worked okay. So I then tried pointing to the file directly as this is what I will need to do, but I started getting problems. I've included the code below. When I do the original xml to cursor I get the document header information which I can then validate etc. I then try to use the second half to get the detail lines. This worked if the code referenced the OriginalFile string, however it will not work if I use FileToStr of the xml file or similar variations. The fact that it worked when part of the file but not when passed as a variable has me baffled. Any further help appreciated.

Edit: despite lcXMLFile having data, when I do the command m.XML.loadXML(lcXMLFile) it returns no data.

LOCAL lcFilename, lcFolder
lcFolder = SYS(5) + SYS(2003) + "\"
lcFilename = lcFolder + "Orders-120620171535_9401-2.xml"

LOCAL OriginalFile AS String

TEXT TO m.OriginalFile NOSHOW
<?xml version="1.0" encoding="utf-16"?>
<Orders xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	..... All relevant fieldsa
</Orders>
ENDTEXT

* this will do for the top level
*XMLTOCURSOR(m.OriginalFile, "Orders")
XMLTOCURSOR(lcFilename, "Orders", 512)


BROWSE

* to fetch the orders details, we'll have to transform into another XML document
* this will fetch also, as columns, the order ID that applies to the detail, and
* the Item Type Number (whatever that may be)
