RegEx Match Open Tags Except XHTML Self-Contained Tags Matching open HTML tags while excluding XHTML self-closing tags is a common task when working with HTML using regular expressions. In this post, we'll walk through how to construct a regex that matches open tags (like <div> ) but ignores self-contained tags (like <img /> or <br /> ). Understanding the Problem HTML open tags typically have the following structure: <tagname [attributes]> Self-closing tags in XHTML include a / before the closing > , like this: <tagname [attributes] /> The goal is to match only open tags that don't have the self-closing slash. The Regex Solution Here’s the regex pattern you can use: <([a-zA-Z][a-zA-Z0-9]*)\b[^>]*?(?<!/)> Explanation of the Regex <([a-zA-Z][a-zA-Z0-9]*) : Matches the opening < and captures the tag name. The tag name must start with a letter, followed by optional al...

What is a NullPointerException, and How Do I Fix It? A NullPointerException (NPE) is one of the most common runtime errors in Java. It's frustrating, yet completely avoidable when you understand what causes it and how to handle it. What is a NullPointerException? A NullPointerException occurs when your code attempts to access or modify an object or variable that hasn't been initialized—meaning it points to null . Essentially, you're trying to use something that doesn't exist. Consider this simple example: // Example of NullPointerException String name = null; System.out.println(name.length()); // This will throw a NullPointerException In this case, the variable name is null , so calling length() on it results in an error. Common Causes of NullPointerException Accessing methods or properties of a null object. Forgetting to initialize a variable. Returning null from a method and not checking for it. Incorrect assu...

How to Make a Great R Reproducible Example? Have you ever posted a question about R on forums like Stack Overflow and received the dreaded response: "Can you provide a reproducible example?"? Crafting a good reproducible example is the key to getting the help you need. In this guide, you'll learn how to create a concise, clear, and complete example that others can easily run and debug. What Is a Reproducible Example? A reproducible example (or reprex ) is a minimal, self-contained piece of code that replicates an issue or demonstrates a concept. It allows others to quickly understand your problem without additional context or guesswork. Pro Tip: Use the reprex package to make this process easier! Steps to Create a Great Reproducible Example 1. Isolate the Problem Start by identifying the smallest piece of code that reproduces your issue. Remove all unrelated elements like unused variables, extra functions, or unnecessary libraries. ...

What Does the yield Keyword Do in Python? In Python, the yield keyword is used to create generators , a type of iterable that allows you to produce a sequence of values lazily—meaning one at a time, as they are requested. Unlike a regular function, which runs to completion and returns a single value, a generator function yields multiple values over time, preserving its state between calls. How yield Works When a function contains the yield keyword, it becomes a generator function. Instead of using return , which exits the function completely, yield pauses the function, saving its state, and produces a value. The next time the generator is called, execution resumes from where it left off. def count_up_to(n): count = 1 while count Output: 1 2 3 4 5 What Happens Here: Calling count_up_to(5) doesn’t run the function. Instead, it returns a generator object. Each time next() is called on the generator (implicit...
