You may refer to the 'XML' property for it's XML representation of the node and all its descendants.

*&  from your example.
*&
loOutput = CreateObject( "MSXML2.DOMDocument.3.0" )
*** now i should use .AppendChild() or the like of loOutput to
*** fill in the xml object.
*&
*&  Add this line to get the XML raw text.
lcOutputXML = loOutput.documentElement.XML
*&

>Here is some code from my com app:

>PROCEDURE GetCars( InXml as String ) AS String
>LOCAL lcReturn, loXML, loRoot, loElement
>LOCAL loOutput, loOutRoot, loOutElement
>		
>LOCAL lOpCode, lCountry
>
>lcReturn = "test"
>*** fills in the xml with the InXml param.
>loXML = CREATEOBJECT( "MSXML2.DOMDocument.3.0" )
>loXML.loadXML( InXml )
>loRoot = loXML.documentElement
>*** then i loop through the nodes of loRoot, and do some stuff with it
>*** the result of that stuff should be appended to some new xml string
>
>loOutput = CreateObject( "MSXML2.DOMDocument.3.0" )
>*** now i should use .AppendChild() or the like of loOutput to
>*** fill in the xml object.

>I know i could then use loOutput.Save method to save the xml into a file and then RETURN (FileToStr(thexml.xml)), but that's what i want to avoid. How can i return the xml as a string?

>>>Hi All
>>>Here is the scenario. I have an ASP page that receives as param. an XML string, calls a VFP COM that does some work on it and returns a new XML. This newly created XML is then sent back by the ASP.
>>>The ASP part works well. It basically runs something like

>>>MyVFPCom( xmlIn, xmlOut )
>>>Response.Write( xmlOut )

>>>My problem is with the creation of the xmlOut string. How do i create it? I would like to avoid having to create a .xml file then send the FILETOSTR of the file, but rather just work on memory.
>>>So, how can i create the XML string from the MyVFPCom?

>>>TIA
