Reading XML

XML (Extensible Markup Language) files represent an organized method to save and quickly read information from files.

How to do it...

Use the following steps to read the XML data:

1. Create a new main stack in LiveCode.

2. Set the background color of the main card to black.

3. Drag a new button to the card and assign the following properties:

   • Name: btn_readXML

   • Label: Read XML

   • threeD: Keep it unchecked

   • showBorder: Keep it unchecked

   • hiliteBorder: Keep it unchecked

   • backgroundColor: White

4. Create a text file with the following text. Save the file as sample.xml into the documents folder on your mobile device:

   <sample>
     <language>English</language>
     <timeZone>ET</timeZone> 
   </sample>

5. Assign the following code to the btn_readXML button:

   on mouseUp
     local xmlTree, tLanguage
     
     # Read XML File into memory
     put readXMLtoTree() into xmlTree
     
     # Retrieve specific piece of information
     put revXMLNodeContents(xmlTree, "sample/language") into tLanguage
     
     # Release...
