Question

First of all, I know that you shouldn’t try to use regex to modify XML, this is a special case where I have to do that anyway and not use a parser.

I want this:

<nicetag_A-B>Teststring X-Y</nicetag_A-B>

To look like this:

<nicetag_>Teststring X-Y</nicetag_>

In short, I want to remove [any letter]-[any-letter] but only from the tag, not the actual content inside.

This is my regex so far:

Regex.Replace(inputString, @"(<.*?[a-zA-Z])\-([a-zA-Z].*?>)", "$1$2");

The problem with this is that it only works for the example above, if the tag would be named without A-B, the inner content (X-Y) would be replaced instead.

Any ideas?

Answer 1

Your example isn’t working, its replacing only the hyphen in the tag.

Try this here

(<[^>]*)[a-zA-Z]\-[a-zA-Z]([^>]*)

and replace with $1$2
