Hello,
Is there a common way of stripping html tags from a string? Right now
I’m
just calling gsub!(/<.*?>/, ‘’), but with a background in PHP and always
having used its strip_tags() method, I wonder if the Rails community has
standardized this fairly common task with something a bit less
simpleminded
than my quick fix.
Thanks!
Zack

Suspect you want the erb html_escape method
http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/classes/ERB/Util.html#M000688html_escape
<%= h string %>

Or I suspect that I should actually read what you wrote …
PHP: strip_tags - Manual describes the php
strip_tags, and points out a number of interesting problems that it
might have under some circumstances, and a few good workarounds.
Simply gsubbing the <…> instances away isn’t quite the same as
rendering the document, but I can’t see anything that does that. I guess
finding a “nicer” replacement depends on your source data, and what
you’re trying to achieve …

If I escape the html, it just converts the html entities into the &??;
form.
I want to strip html tags, and end up with a string containing no html
tags. This is the PHP equivalent of what I’m talking about:

Just what I was looking for. This is odd though, I’m running the
following
html = ActionView::Helpers::TextHelper::strip_tags html
And getting a NoMethodError. rails --version tells me I am indeed
running
1.1.2 though. Any ideas?
Thanks,
Zack
Well, perhaps strip_tags isn’t perfect, but I’m not necessarily looking
for
a port here. I’m just looking for a method whose stated goal is to
remove
html tags from a string.
I’ve been using this ruby sanitize:

which lets you specify some tags to allow and strips the rest.
cheers,
