Match(String, Int32, Int32) Searches the input string for the first occurrence of a regular expression, beginning at the specified starting position and searching only the specified number of characters. Match(String, String, RegexOptions)
If your goal is to match numeric values containing a certain number of digits, then use \d together with an appropriatequantifier. For example, to match invoice numbers consisting of exactly 7 digits, you'd use \d{7}. However, please keep in mind that it will match 7 digits anywhere in...
In regular expressions, braces (also called quantifiers) are used to specify the number of times that a character or a group of characters can be repeated. For example, the regular expression [0-9]{2,3} means: Match at least 2 digits, but not more than 3, ranging from 0 to 9. "[...
Pattern match operators only match one character sans repetition operators so you don't need the {1} indications. Use raw strings, r"\d", when dealing with patterns to keep Python from messing with your back slashes. Your description and your examples don't match exactly so I'm making...
g modifier:global. All matches (don't return after first match) m modifier:multi line. Causes^and$to match the begin/end of each line (not only begin/end of string) i modifier:insensitive. Case insensitive match (ignores case of[a-zA-Z]) ...
Extract first number This is as simple as regex can get. Given that \d means any digit from 0 to 9, and + means one or more times, our regular expression takes this form: Pattern: \d+ Setinstance_numto 1 and you'll get the desired result: ...

[EDIT]: To add some details, based on questions from the comments: Obviously it is fairly trivial to implement this as a function in most programming languages. However,I was originally looking to implement this as a regex, because I was trying to match certain records in a databas...
