Property Detail

source

property
source:XMLList

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The underlying XMLList for this collection. The XMLListCollection object does not represent any changes that you make directly to the source XMLList object. Always use the XMLListCollection methods to modify the collection.

This property can be used as the source for data binding. When this property is modified, it dispatches the listChanged event.

toString

()method 
override public function toString():String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.

Returns
String — The string representation of the XMLList object.

Returns a string representation of the XMLList by calling the toXMLString() 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 concatenated, without separating return characters.

The toXMLString() method preserves 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 toString() method if you want to strip these from the returned string for XML objects with simple content.
