roXMLElement GetBody() and GetchildElement() methods

Archived

I’ve finally gotten around to trying to consume some XML from within BrightScript.
The documentation on the roXMLElement object is a bit light.

Can someone explain to me the difference between roXMLElement.GetBody() and roXMLElement.GetChildElements()?

They seem to be used interchangeably in the VideoPlayer sample.

Thanks,

D.

I just started working with this too, last night. I think GetBody(), along with GetText() gives you the contents of the element in string form, which GetChildElements() returns an roXMLList or roXMLElement if there’s only one.

If I’m remembering correctly, I believe GetChildElements() actually returns and array of roXMLElements instead of an roXMLList as you might expect.

Actually, I just tested it in the debugger.
They both return an roXMLList.

Go figure :?

Hrmm.. I wonder if it was GetNamedElements() that returned an array… I know I ran across one of the roXMLElement methods that returned an array. I swear! :face_with_tongue:

GetChildElements() reurns an roXMLList. If there are no children, it returns an empty list.

GetBody() returns an roXMLList if the body is not a leaf. If the body is a leaf node, it returns a string.

Ahh. A subtle, but distinct difference.

Thanks!
