Hello, I am new here

I have tried everything to delete blank lines. It worked once but then I could not get it to work again. I've used ^\n and also ^ *\n. I've gone into preferences and seleceted editor and tried checking and unchecking "Use POSIX regular expression syntax" and neither has worked. I am working with an xml file. I've also converted it to a text file.

It's been a while since I used Regular Expressions, so I sure would appreciate anyone's help.

Thanks!!

The style of regex syntax is not significant in this case.

Presumably you've selected Regular expression.

Might there be tabs on these lines? If so, try
^[ \t]*\n
(There's a space in front of the \t).

Thanks Ben! That worked great. Really appreciate your quick response.

Thanks!
