Preguntas frecuentes
What is a Regex Tester?
A Regex Tester is a tool designed to help developers and users test Regular Expressions (regex) against a sample string of text. It highlights matches, captures groups, and helps debug complex patterns in real-time.
What are 'Flags' in regex?
Flags modify how the search is performed. Common flags include 'g' (global search for all matches), 'i' (case-insensitive search), and 'm' (multiline mode, where ^ and $ match start/end of lines).
Why do some characters have a backslash before them?
In regex, certain characters like ., *, ?, +, ^, $, etc., have special meanings. If you want to match the literal character itself (e.g., a period), you must 'escape' it with a backslash (e.g., \.)
How do I capture specific parts of the match?
You can use parentheses () to create capturing groups. The text matched inside the parentheses is stored separately and can be referenced later (e.g., as $1 or \1) or extracted individually.
What does the 'g' flag do exactly?
The 'g' flag stands for 'global'. Without it, the engine only returns the first match found in the string. With it, the engine continues searching the rest of the string to find all possible matches.
Why is my regex matching too much text?
Quantifiers like * and + are 'greedy' by default, meaning they match as much text as possible. To make them match as little as possible (lazy), append a question mark, e.g., change .* to .*?
