Subject: RE: [Flashnewbie] Reading and displaying RSS feeds in Flash MX
For some reason, the first slash is missing in that code I posted. First
line should be:
/**
not:
**
But you probably figured that. (....And you probably know you don't need
the comments section anyway - I just like to give people credit and keep
track of where I got the code from. Obviously the code starts with the line:
XML.prototype.toObject = function(input_xml)
)

:::>:::>:::>This is the reason I use classes like the link I posted

:::>:::>:::>a string. If there is more than one, it creates an array
:::>:::>:::>for each node and
