XML Essentials:Data Structuring, Parsing & Integration

Explore the basic rules of XML, including content types, proper syntax, nesting, attributes, and validity. Learn about document declarations, encoding, standalone, namespaces, and validating XML with types, definitions, and schemas.

Enforce XML syntax, stricter than HTML, by ensuring a single root tag, well-formed structure, properly nested tags, closing empty tags with a slash, and quoted attribute values.

Learn how XML documents become valid beyond well-formedness by applying rules through document type definitions and XML schemas, including their strengths and limitations.

Explore how XML namespaces prevent tag name collisions when combining HTML data with custom tag sets by using xmlns definitions, default namespaces, and prefixes.

Create your xml file in a text editor, declare the xml declaration, add an example tag with text and a comment, save, and view the raw xml in a browser.

Link an external CSS file to an XML document to apply styling, and define display, font family, size, and color.

Associate a CSS stylesheet with an XML document to style a business card, defining CSS for name, phone, and email tags with color, bold font weight, and block display.

Apply advanced CSS to label XML content using before and after pseudo-classes, display email and primary phone labels, and render multiple business cards from a single XML document.

Explore the Document Object Model (DOM) to manipulate XML content as a tree of nodes, using properties like nodeName, nodeType, and attributes, and methods like appendChild and getElementsByTagName.

Discover how to use dome dom APIs to extract xml data embedded in html, retrieving a business card’s name and email with getElementById and getElementsByTagName.

Utilize the dom api to create and render multiple business cards from xml data by looping, creating elements, setting attributes, and appending content to the document body.

Explore XPath, the W3C standard for querying XML data, using path notation to extract nodes, attributes, and text with predicates and location steps; learn through practical examples and hands-on practice.

Apply XPath on XML data in VS Code with the XML developer plugin to select name and phone text, using text(), contains, and predicates with attribute filters such as type.

Explore how XSLT transforms XML data using templates to produce output in XML, PDF, Word, or HTML, and perform operations like loop and sort.

Explore common XSLT elements such as template, match, value, for-each, if, choose, and sort, and learn how to transform XML into HTML or other formats using a stylesheet.

Explore xslt by transforming a simple xml with a stylesheet that matches the java code tag using xpath, extracts its text, and injects it into an html result.

Discover how XSLT and CSS work together by linking a CSS stylesheet to the XSLT-generated HTML and observing background color, image, and text alignment.

Learn how to transform a repeating set of XML items into HTML using XSLT, looping with xsl:for-each and select, and rendering each item's photo, name, and type.
