I want to know if there is a way to "search" on an xml file and bind that data
to a dataGrid based on that search..

basically like if you were searching through music:

<song id="0">
<title>My Song</title>
<artist>The Artist</artist>
</song>
<song id="1">
<title>Another Song</title>
<artist>The Artist</artist>
</song>
<song id="2">
<title>Disco Fever</title>
<artist>The Artist</artist>
</song>
<song id="3">
<title>Funky Guy</title>
<artist>My Artist</artist>
</song>

and then search for "song" in the song field or "The Artist" or "Artist" and
have it return anything that has those parameters in them. And if thats
possible, is it possible to search on more than one.. say all artists with
"Artist" in the field and "Song" in the title

Put the XML into an XMLListCollection and then use the filterFunction to filter
out the data you want to see. Take a look at the api for the XMLListCollection
/ filterFunction.

here is a link that explains

Thanks I'll check it out!

Haven't looked at the XMLListCollection yet.. but did check out the
dispatchevent link. I did get it to work with the .(node ==) method... but
here is the REALLY fun part

can anyone tell me how to do a "partial search" on a value? like in SQL:
SELECT * FROM mycol WHERE myfield LIKE '%this%'

can you do that with those methods? I can't seem to find anything that will
allow it.

nevermind.. got it
musicSearchXML = music_XML.songs.song.(title.search(textSearchField .text)>-1);

Also,
If you need complex calculations within an e4x expression, you can call out to
a function of your own. The () just requires a boolean value, so you can do
something like below, where I wanted to a bit of string manipulation within the
expression:

xlFilteredItems =
_xmlData..item.(itemContains(attribute("item"),sFi lterString))

and the function:
private function itemContains(sItem:String, sMatch:String):Boolean
{
sItem = sItem.toLowerCase();
sMatch = sMatch.toLowerCase();
return (sItem.indexOf(sMatch) != -1);
}//contains

Tracy,

Would this be able to work on muliple fields.. say if I wanted to search on an artist AND song title? logically it doesn't seem like it would work...

Sure, that would work. Consider an expression like this:
var xl:XMLList = xml..(doMySelectionLogic(*));

I am not exactly sure that "*" is the right syntax to pass in the current
node, it might be ".", but whatever, we could figure that out.

In doMySelectionLogic(xmlCurrentContextNode:XML):Bool ean, we could use an e4x
expression to find any value anywhere in the xmlhierarchy we needed. We could
use parent().parent().. to move directly up the hierarchy. We could use
ordinary expressions to move down. We can loop over any subset we want. We
could examine global variables or any other in-scope value we wanted. We could
use Math.whatever. Anything.
