Hello,

I am trying to figure out how to convert an XMLList that I retreived from an
XML instance back into well-formed XML in Flash CS3. Here is what I am doing.
- I have an XML document loaded and I am displaying the contents in a datagrid
component (which is working well).
- I am then filtering the XML to obtain a subset of data by first obtaining an
XMLList representing all elements of my XML instance and then filtering the
list on a particular element (this is working well).
- Now I want to display my filtered results in the datagrid and here lies the
problem because the datagrid can't use an XMLList as a dataprovider. How do I
convert this XMLList back into well formed XML so I can use it as my grid's
dataprovider? I need to somehow get a root tag back on.

Could I somehow use toXMLString() and then convert that to XML?

Thank you in advance for any advice.

TH

I solved this so I thought I would post how I did it in case anyone would find
this useful.

1. First, convert your XMLList to an xml string:

var yourXMLString:String = yourXMLList.toXMLString();

2. Next, add a root tag to the beginning and end of your xml string.

yourXMLString= "<your_root_tag>"+yourXMLString+"</your_root_tag>";

3. Convert the string to xml.

var yourNewXML:XML=new XML(yourXMLString);

yourNewXML is now well-formed xml and will work as a dataprovider.

this helped me re-form filtered XML to set the dataProvider of the List component.

Cheers mate

You could have also done this:

var newXML:XML = <your_root_tag/>

newXML.appendChild (yourXMLList);

Or even better, this works too:

var newXML:XML = <your_root_tag>{yourXMLList}</your_root_tag>;

One step simpler:

new XML( node.toXMLString() )
