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.
I am applying for an IT role in a company that I really like, the manager got interested in my resume and one of the job requirements is knowledge in XML, so I am preparing for the interview. Thank you so much for these videos!
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.🙂🙂💔
Hi Raghav, I truly believe that UA-cam should come up with a kind of bonuses for channels like your’s. You are a great teacher, and your channel moves the world forward, especially considering your courses and lectures are free 👏👏
Sorry to be so off topic but does anyone know a tool to get back into an Instagram account..? I was dumb forgot the login password. I would love any assistance you can offer me
Straightforward and easy to understand material. Many explanation on the web always assumes we have some prior knowledge of certain technical terms already and require us to google more just to understand the explanation. Your explanation clear and concise. Thanks.
Thank u. Needed help in understanding for an assignment. My teachers just gave slides, barely explained anything and confused me. However, this 10 min xml video of your really made everything clear. Thanks again :)
just now completed watching all your videos really helpful sir. Great teacher in YT history making complex topics in to simple manner. Respect to your efforts can't stop thanking you...........
Excellent learning videos. I wish there is a way, where you can give us small, small exercise or practice problems and solutions after we are done. This is like learning 'how to drive a car', but unless and until we are not challenged with a quiz, we won't be able to learn.
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!!!
Apparently, my campus specializes in teaching patience. 3 days on campus vs. 1 hour here🫠 Guess I should've paid tuition fees to this video instead. Thankyou!!
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
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.
@@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
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.
