问题
I want to match words inside angle brackets (html tags):
<MatchedWord></MartchedWord>
This is what I have so far:
/\v\<\w+\>
The problem is that it matches the <> too and the /.
How to do it so it only matches the word?
回答1:
You can assert matching before and after text without including that in the match via Vim's special \zs (match start) and \ze (match end) atoms:
/<\/\?\zs\w\+\ze\/\?>
I've included an optional (\?) slash on both side (e.g. </this> and <this/>. Also note that \w\+ isn't a completely correct expression for XML or HTML tags (but it can be a good-enough approximation, depending on your data).
Alternative
For most other regular expression engines, you need to use lookbehind and lookahead to achieve this. Vim has those, too (\@<= and \@=), but the syntax is more awkward, and the matching performance may be poorer.

You dont need to escape angle brackets (square brackets are []) since they are not special characters. You can use capturing groups
<\/?(.+)>
回答3:
In a non-vim environment, this is achieved using positive lookbehind and lookahead as such:
/(?<=<).*?(?=>)/
This matches the following:
<test> // test
</content> // /content
<div id="box"> // div id="box"
<div id="lt>"> // div id="lt
So as you can see by the final example it's not perfect, but you are using regex on html so you get what you pay for
