Here's my problem: In a .txt file, I need to find and replace thousands of instances of syntax like this:

(see (a053007djfgspwdf))

or

(see (a053007djfgspwdf) and (a54134xsedgeg))

or

(see (a053007djfgspwdf), (a9554xsdfgsdfg) and (a54134xsedgeg))

There is a lot of variety between the beginning (see (a and the ending )) text strings. Can this be set up in Notepad++ using regex? If so, how would I do that? Thanks!

Sorry folks, I just find other answers complicated. (No disrespect intended towards the original posters.)

As this always shows up as the first search result, I'll add this in:

  1. Open the search/replace dialog (CTRL+F then the replace tab)
  2. Tick "Regular Expression" down the bottom
  3. Use .* as the wildcard

For example, I wanted to remove all instances of abp="1314", abp="1313", abp="1312" etc (basically the numbers are all different, which is why you want a wildcard to get rid of them).

In the replace dialog:

Find in what: abp=".*"
Replace with:

(You're replacing anything within those quotes with nothing to get rid of it)

Yes it can! Notepad++ has a RegEx search mode that you can select for all of your RegEx replacement needs.

The example below is a basic replace for anything between (see (a...)) with the exception of a line break. You may need to modify the RegEx or write your own to fit your needs. Here's a great place to help you along with experimenting.

RegEx: \(see \(a.+\)\)

Matched strings:

(see (a053007djfgspwdf))
(see (a053007djfgspwdf) and (a54134xsedgeg))
(see (a053007djfgspwdf), (a9554xsdfgsdfg) and (a54134xsedgeg))


Replace (see (a...)) with replacement

As some of these were too in depth for me to understand, let me show you what I did after reading all of these solutions and more to finally get a better understanding. (this is a simple approach, might not be the best)

I wanted to remove all of my figure elements on the whole web page. Figure 2.1,Figure 1.1,ect.

It was:

<p class="td1-content b8"><span class="stepNumber">2.  </span>Select Memo from the toolbar<br><b>Figure 2.1</b></p>

I wanted it to end up:

 <p class="td1-content b8"><span class="stepNumber">2.  </span>Select Memo from the toolbar</p>

But each

had a different Figure number, so I used this in sublime text 2.

  1. ctrl H
  2. click the ".*" symbol on the bottom right of Sublime text 2, (regex)
  3. typed <br><b>Figure.*</b>
  4. replace with: -left blank

This replaced all of my instances with figures in it. notice I used .* where the numbers would of been. Hope this helps.

Try this pattern: \(see \(a(.*)\) and make sure you have ". matches newline" unchecked and "wrap around" checked.

The exact regex you'd need is:

\(see \(\w+\)((, \(\w+\))*( and \(\w+\)))?\)

For example:

enter image description here

On selecting Find All in Current Document, the result would be:

enter image description here

You can simply use Replace as per your necessity instead.

If you want to include the a as well in the regex, you can use:

\(see \(a\w+\)((, \(a\w+\))*( and \(a\w+\)))?\)
