How to use Local XML for HTTPSERVICE

As we know that used for remote server application. But in case we have local XML file then how we can fetch recored from XML using
1. First create new project in Adobe Flex Builder 3.
File -> New -> Flext Project give some name (say Binod_ShareTrading) and click on Finish.
2. Paste you local XML into src folder (say addressbookdata.xml)

3. Right click on Binod_ShareTrading project and click on properties -> Flex Compiler and come to Additional compiler arguments: and put this info
-locale en_US -use-network=false and click on Apply and OK.
Now it will inform to httpserice that do not look on internet for the given XML file.

4. Now start your code in Binod_ShareTrading.mxml (May be different in your case)

<?xml version="1.0" encoding="utf-8"?>

IMP : Here in the above code you can also find the conversation between XML file to ArrayCollection.


  1. Really it is very useful for my project

  2. a bit confusing how you have formatted the sourcecode :(

  3. Now I have re formatted the code. Hope you will not get confusion again. :)
