PHP code to edit RSS file

randombar

Hi Lads,

I'm slowly getting there with my flickr slideshow problem.

I've discovered that google do a nice ajax feed api that takes in rss and creates a slideshow of it.

My next problem is that flickr rss outputs the small version of the thumbnail

EG

<media:thumbnail url="http://farm1.static.flickr.com/214/499483509_84fdd2043b_s.jpg" height="75" width="75" />

So what I want to do is to keep the rest of the rss and just edit the thumbnail section so it looks like this.

<media:thumbnail url="http://farm1.static.flickr.com/214/499483509_84fdd2043b" />

Is there a few simple commands that will do this for me?
i.e.
take in an html file
replace - _s.jpg" height="75" width="75 with .jpg
and just print the rest?

Thanks for your help
Gary

P.S. Seems like a perl job but would like to do it in php

Here's a pretty basic example of str_replace() to get the ball rolling

<?php
$original_string = '<media:thumbnail url="http://farm1.static.flickr.com/214/499483509_84fdd2043b_s.jpg" height="75" width="75" />';
$stuff_to_remove = '_s.jpg" height="75" width="75" />';
$replace_with = '" />';
$new_string = str_replace ($stuff_to_remove, $replace_with, $original_string);
echo $new_string;
?>

Thanks for that, ya I kinda get the string replace.

I guess my problem is taking the data from an rss file and assigning it to a variable within php.

i.e. something like

$original_string = http://api.flickr.com/services/feeds/photos_public.gne?id=8115115@N08&format=rss_200

Apologies to all I'm a lazy idiot:

<?php

$myFile = 'http://api.flickr.com/services/feeds/photos_public.gne?id=8115115@N08&format=rss_200';
$content = file_get_contents($myFile);
if ($content !== false) {
   $remove = '_s.jpg" height="75" width="75" />';
   $replace = '.jpg" />';
   $new_content = str_replace ($remove, $replace, $content);
   echo $new_content;
} else {
  echo "Error";
}

?>
