BSc (Hons) Software Engineering Module Name: Web Service Development Module Code: WAT 2104C University of Technology, Mauritius NOVEMBER 2024 XML & XML Schema & XML Parsers Content to cover Reading XML XML Validation Parsing XML into Objects Modifying XML Advanced Filtering XML – Short intro XML stands for eXtensible Markup Language. XML was designed to store and transport data. XML was designed to be both human- and machine-readable. XML is self-descriptive: it describes data in a structured format using tags. XML is platform-independent and language-neutral, which makes it ideal for data exchange across systems. Commonly used in web services, configuration files, data storage, and more.  X ML files start wit h an opti onal dec laration line Dholl Puri Rs 30.00 A popular Mauritian street food, served with a variety of curries and chutneys 350 Gateau Piment Rs 15.00 Spicy split pea fritters, a Mauritian snack served with chutneys 150 Roti Rs 30.00 Freshly made flatbread with curry and chutneys, a local favorite 300 XML – Rules Case-sensitive: and are different. Closing tags: Each opening tag must have a corresponding closing tag. Root element: XML files must have a single root element that encapsulates all other elements. Attribute values: Attributes must be quoted.

Make sure you print the values you read from the XML (in this case, food items and the details)  Reading XML Exercise 2: Reading XML file Requirement 1: Read the file from a path E.g. ("path/to/yourfile.xml"); Requirement 2: Print only food items that contain less than 320 calories. Code snippets: XDocument doc = XDocument.Load("path/to/yourfile.xml"); Or XmlDocument doc = new XmlDocument(); doc.Load("path/to/yourfile.xml"); XML Validation Validate an Xml file using the below steps: 1. Use an XSD file to define rules for XML structure and data types. 2. Validate XML data against the XSD using XmlReader and XmlReaderSettings in C#. 3. Observe validation errors when the XML data does not conform to the XSD and understand how to fix them. XML Validation Step 1: Create & Save the XSD File
