Perl Compatible Regular Expressions (PCRE) is a library written in C, which implements a regular expression engine, inspired by the capabilities of the Perl programming language. Philip Hazel started writing PCRE in summer 1997. [ 3 ]
A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .
A regex search scans the text of each page on Wikipedia in real time, character by character, to find pages that match a specific sequence or pattern of characters. Unlike keyword searching, regex searching is by default case-sensitive, does not ignore punctuation, and operates directly on the page source (MediaWiki markup) rather than on the ...
Then click on the "search and replace" icon on the right. In the popup form check the box for "Treat search string as a regular expression". Fill in the "Search for" box with (\|-\n\|) Fill in the "replace with" box with $1style=text-align:left| Then click "Replace all". All the text in the first column will be aligned to the left of their cells.
Approximate matching is also used in spam filtering. [5] Record linkage is a common application where records from two disparate databases are matched. String matching cannot be used for most binary data, such as images and music. They require different algorithms, such as acoustic fingerprinting.

In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation. Reasons for using a naming convention (as opposed to allowing programmers to choose any character sequence) include the ...
Step 2 - Excel; This will look a bit long-winded but I've broken it down into individual cells so that you can see what is going on. You can make it more compact when you understand it. Copy the text to the right of the colon: into the cell indicated. Make sure to include the single apostrophe ' and the spaces.
