I use this filter:

our $line_merger =3D sub {
=09my $text_ref =3D shift;
=09# Removes HTML comment style format from the tags (so that next regex wo=
rks)
=09$$text_ref =3D~ s/<!--\s*(~?\/?TMPL_.+?)\s*-->/<$1>/gis;
=09# "Cleans" tags in such a way that it removes the space characters
and ~ (so if there is no ~ it does not
=09# remove anything)
=09$$text_ref =3D~ s/(?:\n[
\t]*(?=3D<~))?<~?(\/?TMPL_[^>~]+)~?(\/?)>(?:(?:(?<=3D~\/>)|(?<=3D~>))[
\t]*\n)?/<$1$2>/gis;
};

The idea is that I can use ~ character to specify that I want newline remov=
ed.

For example:

<~TMPL_VAR NAME=3D"foo"~>

will remove newline before and after the tag (if there is any).

In most cases I use only second ~ as this efficiently (in most
template uses) removes all newlines after the tags and so there are no
empty lines in the output.
