XML Processing Instructions

Question

Hi,
I have two questions about how the XML class in AS3 works.
First, does the XML class care about the initial processing instruction when created from a string like this?:
<?xml version="1.0" encoding="UTF-8" ?>
<painting>
  <img src="madonna.jpg" alt='Foligno Madonna, by Raphael'/>
  <caption>This is Raphael's "Foligno" Madonna, painted in
    <date>1511</date>–<date>1512</date>.
  </caption>
</painting>
Second, how can I add that procession instruction to an XML object that I am working with so that toXMLString() returns a string that looks like the above XML? (So that it includes the processing instruction.)

Answer 1

Hi!
Normally you won't see processing instructions when working with AS3 and XML but you can change that using the following line of code:
XML.ignoreProcessingInstructions = false;
If you will, you can also see your comments by using the following:
XML.ignoreComments = false;
I think it's usual to use those lines inside your package body, even before your imports but I think you could have it anywhere else (even outside your package body I think).
Hope it helps.
edit: don't forget you can manage those items as a  XMLList too...
