Rails - Aug 2007 - How do you check if text is in between certain <tags>?

For instance, I have a similar block of text like so:
> @text = "Lorem ipsum <code>[some code here]</code> dolor
sit"
What sytax would I use to check if the text is in between the <code>
tags?

That is: "If @text is in between ''<code>'' and
''</code>'' tags, then
do..."

Any ideas?

Maybe you could look at regular expressions.

This regex pattern seems to work

/<code>(.*?)\<\/code>/

extracting the string now is a bit more difficult
-- jarod

If this can / is being done in rjs or javascript, then Prototype has 
methods that can do this.  http://prototypejs.org

REXML::Document.new(''<xml>'' + my_string +
</xml>'')

if ''my target'' ==
REXML::XPath.first(''/xml/code/'').text

Test side, you bottle that up in assert_xpath (or assert_hpricot;).

Not sure why you need it production-side, and that influences the syntax. If 
the whole string comes from the user, you need to tolerate faults, and the 
equivalent Hpricot might work better.

And if the string comes from the user, and you don''t want to abuse them
and
XML at the same time, you could try YAML.
