ActionScript XML to Object - XMLparser

Anyone knows about something like JSON.parse() for XML? Its very annoying to work with XML API-s without a good parse function. I found a reference to SimpleXML, but couldnt find it anywhere. What I need is basically to build up an untyped object from the XML of an API.

We had some luck on a recent project using the mx.rpc.xml.XMLDecoder with a custom Schema.

Our dynamic domain object would extend ObjectProxy. Notice that we have not defined a 'firstAired' Date property.

package com.sample.model
{
    import mx.utils.ObjectProxy;

    [Bindable("propertyChange")]
    public dynamic class Series extends ObjectProxy
    {
        public var seriesId : String;
        public var name : String;
        public var overview : String;
    }
}

We would define our XML Schema (In our project the schema was returned with the results):

var schemaXML : XML = <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

                    <xs:element name="data">
                        <xs:complexType>
                            <xs:sequence>
                                <xs:element name="series" type="series" maxOccurs="unbounded" minOccurs="unbounded"/>
                            </xs:sequence>
                        </xs:complexType>
                    </xs:element>

                    <xs:complexType name="series">
                        <xs:sequence>
                            <xs:element name="seriesId" type="xs:string"/>
                            <xs:element name="name" type="xs:string"/>
                            <xs:element name="firstAired" type="xs:date"/>
                            <xs:element name="overview" type="xs:string"/>
                        </xs:sequence>
                    </xs:complexType>

                </xs:schema>;

A sample XML result would look like:

var seriesXML : XML =   <data>
                           <series>
                              <seriesId>75760</seriesId>
                              <name>How I Met Your Mother</name>
                              <firstAired>2005-09-19</firstAired>
                              <overview>It all started when Ted's best friend...</overview>
                           </series>
                        </data>;

As results were received we put the Decoder to work:

var schema : Schema = new Schema(schemaXML);

var schemaManager : SchemaManager = new SchemaManager();
schemaManager.addSchema(schema);

var decoder : mx.rpc.xml.XMLDecoder = new mx.rpc.xml.XMLDecoder();
decoder.schemaManager = schemaManager;

var schemaTypeRegistry : SchemaTypeRegistry = SchemaTypeRegistry.getInstance();
schemaTypeRegistry.registerClass(new QName(schema.targetNamespace.uri, 'series'), Series);

var data : Array = decoder.decode(seriesXML, new QName(schema.targetNamespace.uri, 'data'));

Inspecting the 'data' Array notice the 'firstAired' property correctly typed as a Date:

Try this XMLParser link.

By using this Every node becomes an array with the same name. All attributes are also easily accessible because they become properties with the same name.
