Flash Builder mobile - complex XML reading

Question

Hello Developers,
Please help me! I'm trying to develop a mobile app, that displays a complex xml file (i'm not a developer, so please be patient... ). Here's the xml file, then I write what I'd like to do:
<?xml version="1.0"?>
<server_status>
<hosts>
   <host>
      <host_name>server1</host_name>
      <modified_attributes>0</modified_attributes>
      <check_command>check-host-alive</check_command>
      <check_period>24x7</check_period>
      <notification_period>24x7</notification_period>
   </host>
      <host>
      <host_name>server2</host_name>
      <modified_attributes>0</modified_attributes>
      <check_command>check-host-alive</check_command>
      <check_period>24x7</check_period>
      <notification_period>24x7</notification_period>
   </host>
</hosts>
<services>
   <service>
      <host_name>server1</host_name>
      <service_description>C:\ Drive Space - Exchange Edge 1</service_description>
      <modified_attributes>0</modified_attributes>
      <check_command>check_nt!USEDDISKSPACE!-l c -w 80 -c 90</check_command>
          </service>
          <service>
      <host_name>server1</host_name>
      <service_description>CPU Load - Exchange Edge 1</service_description>
      <modified_attributes>0</modified_attributes>
      <check_command>check_nt!CPULOAD!-l 5,80,90</check_command>
          </service>
   <service>
      <host_name>server2</host_name>
      <service_description>C:\ Drive Space - Exchange Edge 2</service_description>
      <modified_attributes>0</modified_attributes>
      <check_command>check_nt!USEDDISKSPACE!-l c -w 80 -c 90</check_command>
          </service>
   <service>
      <host_name>server2</host_name>
      <service_description>CPU Load - Exchange Edge 2</service_description>
      <modified_attributes>0</modified_attributes>
      <check_command>check_nt!CPULOAD!-l 5,80,90</check_command>
          </service>
</services>
</server_status>
As you can see, there's 2 main nodes: hosts & services. On the opening screen of the app I can list the hosts displaying in a list the host nodes with host_name. That's fine. I select one of them and on the new view I show the selected host attributes like <modified_attributes>, <check_period>, etc. What I want is to display on this screen the selected host's services. Under the <services> node there are 4 <service> child node: 2 services for host1 and 2 services for host2. I only want to list those services that are belong to the host I selected on the main view.
Please write me the source code of the solution either here or in email ([email protected])
Thanks for your help!

Really thanks for your reply, but I don't really know, where and how to put in the code. Here's the mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
                    xmlns:s="library://ns.adobe.com/flex/spark"
                    xmlns:szolgaltatas="services.szolgaltatas.*"
                    title="DetailsView"
                    viewActivate="getDetails()"
                    >
          <fx:Script>
                    <![CDATA[
                              import mx.events.FlexEvent;
                              [Bindable] private var ha:String;
                              [Bindable] private var hb:String;
                              [Bindable] private var hc:String;
                              [Bindable] private var hd:String;
                              import valueObjects.Host;
                              import valueObjects.Service;
                              private function getDetails():void
                                        var thisItem:Host = data as Host;
                                        ha = thisItem.last_time_up;
                                        hb = thisItem.last_check;
                                        hc = thisItem.plugin_output;
                                        hd = thisItem.host_name;
                              protected function textArea_creationCompleteHandler(event:FlexEvent):void
                                        getDataResult.token = szolgaltatas.getData();
                    ]]>
          </fx:Script>
          <fx:Declarations>
                    <s:CallResponder id="getDataResult"/>
                    <szolgaltatas:Szolgaltatas id="szolgaltatas"/> <!-- Szolgaltatas service -> getData(): Service[] -->
          </fx:Declarations>
          <s:Label top="10" left="10" right="10" text="Time Up: {ha}"/>
          <s:Label top="30" left="10" right="10" text="Last Check: {hb}"/>
          <s:Label top="50" left="10" right="10" text="Check Result: {hc}"/>
          <s:Label top="90" left="10" right="10" text="Hostname: {hd}"/>
          <s:TextArea id="textArea" left="10" right="10" bottom="10" height="50%"
                                        creationComplete="textArea_creationCompleteHandler(event)"
          />
</s:View>
Thank you Jakub!
