Re: [flexcoders] parsing complex xml
You should really be copying from your XML object into a flatter AS object
first - for binding and inline editing and whatnot as the XML objects
contain *much* voodoo that can bite you. But here's a quick example using a
datagrid rather than a list. As for updating and persisting the XML object,
that exercise is left to the reader ;-)

Re: [flexcoders] parsing complex xml
I was trying both routes- dataprovider and and iterating.
dataProvider:
function dataReceived(data:XML):void
{
list.dataProvider = data.configuration.category;
}
With the above, nothing showed up in the list. The xml sample I provided in
my original email was all wrapped by a con tag by the server.
Iterating over it I tried:
function dataReceived(data:XML):void
{
for (var category:XML in data.configuration.category)
{
trace(category.toXMLString();
}
}
The flex page that needs to render this will allow the user to configure
each item, so I need a way to read and write to those items while still
leaving the comments in tact.
Thanks!

Re: [flexcoders] parsing complex xml
Yeah, I should have mentioned that the server sending this file to me is wrapping it in con, making that the root and configuration the only element.

Re: [flexcoders] parsing complex xml
Off the top of my head, If the root of your XML doc is , you want xmlObject.category as a list of elements, not xmlObject.configuration.category -J On Wed, May 28, 2008 at 8:09 AM, dfalling <[EMAIL PROTECTED]> wrote: > I'm trying to parse a complex xml file (a log4j config file) and am > running into a number of problems: > > * Flex seems to remove all the comments from the file.

RE: [flexcoders] parsing complex xml
I don't know if I have ever noticed this removal of comments, I'd need to verify. To iterate over nodes, use an e4x expression to return an XMLList, then use a for loop. Or For Each, or For In. The docs have some more detail and examples. A list can also use XMLList as a dataProvider if you do not plan to programmaticlly update the dataprovider. If you do, simply wrap the XMLList in an XMLListCollection. It looks like you will need to declare the default namespace, or use the namespace::node in all e4x expressions. You've not shown any expressions, so I can't say what you're doing wrong.
