I have documents with groups of <hr/> tags:
<p>stuff</p>
<hr/>
<hr/>
<hr/>
<p>stuff</p>
Grateful for tip how to replace with a single instance of this tag in Vim.

You can make <hr/>\n a group and search for multiples of it, replacing
with a single one. Also note that in Vim you can use different
delimiters, which is specially helpful if you're working with slashes
for example. And you don't need to close the substitute command if you
don't have flags.
:%s#\(<hr/>\n\)\+#\1
With \v to enable very magic, even more escaping is avoided. However
the < and > will be treated as special word boundaries. So you have
to escape them instead.
:%s#\v(\<hr/\>\n)+#\1
And of course, if the only duplicated lines in your file are those tags, this is enough as well:
:%!uniq

You can use this search-replace in vim:
:%s/<hr\/>\n\(<hr\/>\n\)\+/\1/
<hr\/>\n\(<hr\/>\n\)\+ will find 2 or more lines containing <hr/> and we replace it using \1 which is <hr/>\n.

Nice, thanks. Do parentheses replace square brackets in Vim?

Actually sorry I'm getting
E488: Trailing charactersgeotheory
Re square brackets no it's just I was trying earlier to achieve this with
[<hr\/>] but always get Pattern not foundgeotheory
That works ta. I just got
:%s/<hr\/>\(\n<hr\/>\)\+/<hr\/>/r to work also. Super helpful thanksAlso works:
:%s/\(<hr\/>\n\)\+/<hr\/>\r
