Embedded Files
Overview
Overview
XML data-driven development separates configuration from code by storing game/application data in XML files. Instead of hardcoding values, developers define behaviors and properties in external XML files that can be easily modified without changing the core application code. This approach simplifies game content and behavior by editing XML files rather than programming code. Key benefits include easier maintenance, rapid iteration, and the ability for non-programmers to modify application behavior through structured data files.
XML Structure
XML Structure
XML (eXtensible Markup Language) is a format for storing and sharing structured data. It uses tags like HTML:Â
The key rules are:
Must have opening and closing tags
Elements can be nested
Tags are case-sensitive
All elements need a root element
Parsing
Parsing
When processing an XML document, the parser first validates that the file exists and can be accessed. Then it looks for the document's root element, which serves as the starting point for traversal. Once the root is confirmed, the parser begins navigating through the document's structure.
Starting with the root's first child element, the parser can extract and interpret all of its attributes. From there, it has two options for continuing: it can either move horizontally to examine the next sibling element at the same level, or it can move vertically by diving deeper into the current element's children. This navigation pattern reflects XML's tree-like structure, where you can either explore deeper into nested elements or move across elements at the same level - similar to how you might explore the branches and leaves of a tree.

Parsing data from XML element by find the attribute name and define the default value in case the system can't find it
