Re: Regular Expression

[adam]

More elegant would be:

/^[a-z]+$/i

The i specifying that it is case-insensitive

irc.freenode.net #regex is a better place for your question, btw

Right on,
 
I ended up using 
 
'rule' => array('custom', '/^[A-Za-z ]+$/'), and that seems to work.
 
Thanks,

Is there something wrong with this expression?


I think you need to specify how many characters you need.  E.g.
/^[a-zA-Z]+$/ for at least one alpha char.

I think you need to specify how many characters you need.  E.g. /^[a- 
zA-Z]+$/ for at least one alpha char.

Your parens are off. The negative lookahead assertions should group all
the alternatives, so try:

\b(?!(?:curriculum|courses|facilitators|configuration))\w+\b

Re: Regular expression in Router::connect

By the way, I need it to exclude multiple strings. So something to the
effect of:

Router::connect('/:group/:curriculum/*',
array('controller'=>'curriculum'),array('curriculum'=>'!xyz AND !abc
AND !mno'));

This is absolutely great. I will keep in mind these modifiers. Great answer

There is almost no chance for it to be faster then a specific regex, afaik.

How does SimpleXML or DOMDocument->loadHTML performance in term of simply
finding certain form elements? Is there a requirement in installation of
PHP?

Why not use SimpleXML or DOMDocument->loadHTML() ? From there you'll
have access to the complete DOM of the HTML.

Re: Regular Expression to find content inside a tag pair

[Felix Geisendörfer]

Off the cuff I'd say: /(.*)/iUs.

Most important are the modifiers:

* i: Makes sure upper/lower- case are ignored (some people might use
  )
* U: Makes sure that all quantifiers are ungreedy, meaning that
  they'll try to match the least amount of data only
* s: Is the most important one, because it wil allow for the '.'
  character class to match line breaks which most forms will contain.

Let me know if that works for you or not,

Re: Regular Expression to find content inside a tag pair

[Dat Chu]

There are several things with anuke's pattern:

First, it will not catch forms with attributes (=> my bad for not specifying
this)
Second, since * is greedy if I have 2 forms, it will capture the content
between the wrong pairs of tags.
Example of this: AAABBBCCC

anuke's pattern will match the whole thing instead of just the first pair.
