Returns a string representation of the XMLList by calling the toString() method for each XML object in the XMLList. If the prettyPrinting property of the XML class is set to true, then the results for each XML object in the XMLList are separated by the return character. Otherwise, if prettyPrinting is set to false, then the results are simply concatenated, without separating return characters.

The toString() method strips out the following in the returned string for an XML object that has simple content: the start tag, attributes, namespace declarations, and the end tag. Use the toXMLString() method if you want to preserve these in the returned string for XML objects with simple content.
