Hi,
I have the following XML not well-indented code:

<hallo
>this is a line
</hallo>

So I need to remove the newline.

This syntax finds what I need to correct, but I don't know how to remove the newline after my pattern:

sed 's/<.*[^>]$/&/'

How can I subtract the newline after my pattern, please?

Thank you in advance,
Nico
