Simple Regex failing in Notepad++ (with angle brackets)
A Regex in Notepad++ is not behaving as I expect, and I'm wondering if it's a bug in Notepad++ or something else.
Here is my file:
<File Name="NAME.EXT">0123456789ABCDEF</File>
Here is my Regex: (\<File .+?\>)
Here are all search settings:
When I pressed Replace All, here is what I got:
<File Name
="NAME.EXT">0123456789ABCDEF</File>
Here is what I expected instead:
<File Name="NAME.EXT">
0123456789ABCDEF</File>
I switched to the Find tab, and even there, it is only matching <File Name
When I load it into regex101.com and selected the "PCRE" flavor (I read that this is what Notepad++ used), it behaves as I expected, not as Notepad++ behaves.
You have to remove the escaping backslashes \.
Explanation: The documentation states
\<⇒ This matches the start of a word using Boost’s definition of words.
\>⇒ This matches the end of a word using Boost’s definition of words.
This is not common use of regular expressions but means that you must not escape the < and > characters to match them.
Additionally you could remove the group and replace the complete match:
Find what:
<File .+?>Replace with:
$0\r\n
This will also get you the result you expect - but if your real input and the real pattern are more complex, the grouping with () might still be relevant.
