Not even Firefox supports as much as Opera does. Thanks, Ash http://www.ashleysheridan.co.uk
From: "Peter Pei" on 3 Apr 2010 10:14 No javascript's getElementByID() won't work here. As "question" is a class, not an ID. But like what was mentioned here, you can use getElementByClass() with Opera, and that will work.

I don't know any possibility to easily process contents which are not valid XML/XHTML just because there's no library to load such stuff (but put me in right there). I'm not an expert of REGEX, but I think the following would do it: /\<p\s*class\=\"question\"\s*\>(.*)\<\/p\> (my first contribute here, I beg your pardon if something went wrong) Regards, Valentin Dreismann

A possible better way are regular expressions... Greetz Piero

If you are open to use javascript then a js library like jQuery may help in selecting all elements from a particular class. $(".clasName") Thanks, Vikash Kumar -- http://vika.sh On Sat, Apr 3, 2010 at 8:46 PM, Piero Steinger <piero(a)the-admins.ch> wrote: > On 03.04.2010 16:29, tedd wrote: > > Hi gang: > > > > Here's the problem. > > > > I have 184 HTML pages in a directory and each page contain a question. > > The question is noted in the HTML DOM like so: > > > > <p class="question"> > > Who is Roger Rabbit? > > </p> > > > > My question is -- how can I extract the string "Who is Roger Rabbit?" > > from each page using php?
