This seems to be hunky-dorie
But it isn't.
If you start with $value being
"<a href='foo'>bar</a>bla<br>bla<a href='bar'>foo</a>";
you end with $value being
"<a href='foo'>bar</a>blabla<a href='bar'>foo</a>";
You're bitten by the notion that
/PAT1'(.*?)'PAT2/ will not end up with a
' in $1.
I'd go with:
while ($value =~ /href='\K([^']*<br>[^']*)(?=')/p) {
my ($pre, $post) = (${^PREMATCH}, ${^POSTMATCH});
my $href = $1;
$href =~ s/<br>//g;
$value = "$pre$href$post";
}
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
