Replacing Source in The Twenty-First Century
October 18, 2016 Ted Holt
In Searching Source in The Twenty-First Century, I introduced the use of regular expressions for searching within a source member. Searching is great, but sometimes you need to replace what the system finds with something else. Here’s how to replace text when using regular expressions.
Let’s begin with a source member.
Instead, let’s use a regular expression to find the instances where Stat is followed by a digit.
Now it’s time to replace, but what is the replacement string? If I replace the matched characters with Status_, the digit will be obliterated, and I don’t want that. What I want to do is to replace that digit with itself, and to do that, I use a capturing (or capture) group.
Using regular expressions to search and replace text is like a multitude of other things you’ve done. Once you do it a few times, you’ll wonder why you ever thought it was hard.
