XML Schema (XSD) Beginner Tutorial with Demo

[@tiranito2834]

This was the best video ever on this subject. I simply don't get why teachers feel the need to overcomplicate things during explanations, they only cause themselves to make mistakes and leave us with a half assed class where all we say were validation failures for 2 hours on end. This video has singlehandedly carried all programmers and people learning XML through their degrees or bootcamps for 3 years straight. Thanks a lot. One of the things that this video does implicitly that no other resource explains (surprisingly not even official documentation explains this lol) is the reason WHY we use a separate tag for complex elements instead of it just being a type attribute as with the other fundamental types. By learning what you learn in this video, you also end up understanding WHY the schema works in the first place and what the purpose of the definitions within the URI are.

[@RaghavPal]

I am so humbled to read this.. Thanks a lot.

[@rehabalsaadi7335]

i hope my professor to open your video and start Learning before he came to the class and And he teaches us wrong things and complicates the subject.🙂🙂💔

I learned a lot about XML from just 7 videos; thank you very much. I began XML because I recently completed a java course and now I'm on my way to create my first app. Will you upload more videos about XML? And also, where should I go from here or what else should I learn if I want to make an android app using XML for UI and Java for back-end? Again, thank you very much!!!

Sir you are really an amazing teacher to help me on alllll API content also ,my doubt is how to edit XML datas using JAVA sir ,any video from u is there before

[@RaghavPal]

I do not have a video but here's a guide on editing XML data using Java: 1. Choose a Parsing API: - DOM (Document Object Model): - Loads entire XML document into memory for tree-like manipulation. - Ideal for small to medium-sized files and frequent modifications. - SAX (Simple API for XML): - Processes XML sequentially, event-driven approach. - Suitable for large files and memory-efficiency. - StAX (Streaming API for XML): - Pull-based parsing, offering more control over parsing flow. - Useful for large files and specific parsing needs. 2. Load XML Document: - DOM: ```java DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document doc = builder.parse("your_xml_file.xml"); ``` - SAX: ```java SAXParserFactory factory = SAXParserFactory.newInstance(); SAXParser parser = factory.newSAXParser(); XMLReader reader = parser.getXMLReader(); reader.setContentHandler(new YourContentHandler()); // Implement ContentHandler reader.parse("your_xml_file.xml"); ``` 3. Navigate and Modify: - DOM: ```java // Access elements: NodeList nodes = doc.getElementsByTagName("elementName"); Node firstElement = nodes.item(0); // Modify attributes: Element element = (Element) firstElement; element.setAttribute("attributeName", "newValue"); // Modify text content: element.setTextContent("New text content"); ``` - SAX: Handle events like `startElement`, `endElement`, `characters` in your `ContentHandler` implementation to modify data as it's parsed. 4. Save Changes: - DOM: ```java TransformerFactory transformerFactory = TransformerFactory.newInstance(); Transformer transformer = transformerFactory.newTransformer(); transformer.transform(new DOMSource(doc), new StreamResult(new File("updated_xml_file.xml"))); ``` - SAX: SAX doesn't directly modify the original document. Implement writing logic within your `ContentHandler`. Additional Considerations: - Namespaces: Handle XML namespaces appropriately for correct element retrieval. - Validation: Consider validating XML against a schema (DTD or XSD) to ensure consistency. - Libraries: Explore libraries like Xerces, JAXB, or JDOM for advanced features and convenience.

[@lrpbro6945]

@@RaghavPal thank u so much sir it's working fine , but it's showing the error called JAVA LEAKAGE ERROR sir , how to solve that sir , please tell me sir inside the KATALON STUDIO

[@RaghavPal]

Before tackling the error, let's pinpoint its source. Here are some steps to diagnose the Java leakage issue in Katalon Studio: Check Logs: Analyze Katalon Studio logs for specific details about the "Java Leakage Error." Identify the object types involved and any related stack traces. Memory Monitoring: Utilize JVisualVM or VisualVM to monitor memory usage during test execution. Identify objects persistently occupying memory, causing a gradual increase. Code Review: Scrutinize your test scripts for potential resource leaks. Common culprits include unclosed network connections, databases, files, or streams. Third-Party Dependencies: Investigate potential memory leaks within installed Katalon Studio plugins or external libraries. esolving the Leakage: Once you identified the source, implement appropriate solutions: Implement Proper Closing: Ensure proper closing of resources like connections, databases, files, and streams using close() or shutdown() methods within your test scripts. Avoid Unnecessary Objects: Minimize object creation within loops or frequently executed sections. Consider reuse or object pooling strategies. Garbage Collection Tuning: Analyze and adjust JVM garbage collection parameters if necessary, but tread cautiously as inappropriate tuning can be counterproductive. Update Dependencies: Check for updated versions of Katalon Studio plugins or external libraries that might address known memory leaks. Consider Reducing Script Complexity: Complex scripts with extensive object interaction or manipulation can exacerbate the issue. Refactoring and simplification might be necessary.

Hello Raghav , this is excellent video for forming XMLs. Really appreciate your hard work to explain everything in detail . Have a quick question - when you declare can you add something like ? If so . what name spaces are needed and where they need to be defined/declared ? Please please let us know Thank you very much

[@RaghavPal]

Hi, Yes, you can add an xsi:type attribute to an xs:element declaration in XML Schema The xsi:type attribute is part of the XML Schema Instance namespace (xsi), and it is used to specify the data type of the element In order to use the xsi:type attribute, you will need to declare the XML Schema Instance namespace (xsi) and the XML Schema namespace (xsd) in the root element of your XML document The namespace declarations should look like this: xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xmlns:xsd="www.w3.org/2001/XMLSchema" And, you need to use this name space in the element where you are using xsi:type attribute as attribute prefix.

[@AD-je9nq]

@@RaghavPal Thank you so much Raghav for responding so quickly , really appreciate it . I have the xml name spaces in the root , but not sure how to use the attribute , i think i tried this ..and it gives error on the name attribute and errors out , no clue about this error on name when we add this xsi attribute . Your inputs will really help Thank you -Ajay

[@AD-je9nq]

Hello Raghav, any clues on why it errors on name tag ? is it supposed to not have the name tag/attribute? Thank you -Ajay

[@AD-je9nq]

Raghav , i am wondering about the significance of xsi:type attribute , why is it used in first place ? am migrating some legacy code that's why the requirement ,,but why cant we use just normal xs:string instead, will it have any impact ?

[@RaghavPal]

The xsi:type attribute is used in XML to indicate the specific type of an element It is a part of the XML Schema specification and is used to provide more information about the element beyond its name The attribute is typically used in situations where an element can have multiple types, and the type information is required to properly interpret the element's content For example, if an element is defined as having a complex type with multiple possible sub-elements, the xsi:type attribute can be used to specify which specific sub-element is present
