RSS/XML feed parser

Here's some php:

function xml_parser($page,$container,$tags,$number,$cdata) {
  if (!$number) {$number=100;}
  preg_match_all("/<$container>.+<\/$container>/sU",$xml, $items);
   foreach ($items as $item) {
    for($i=0; $i<count($tags); $i++) {
    preg_match("/<$tags[$i](.+)(<\/$tags[$i]>)/sU", $item, $tag);
    $this[$i]=array_map('html_entity_decode', $this[$i]);
     if (count($itemsArray)<$number) {array_push($itemsArray, $this);}
  foreach ($itemsArray as $item) {
  for($i=0; $i<count($tags); $i++) {
  $data[$i]=$item[$i][0];    }
   $dpatterns[0]="/<img(.+)><\/img>/sU"; $dreplacements[0]='<img$1>';
   $dpatterns[1]="/<img(.+)\/>/sU"; $dreplacements[1]='<img$1>';
   $dpatterns[2]="/<(\/|)content?(.+|)>/sU"; $dreplacements[2]='';
   $dpatterns[3]="/border=\"0\"/sU"; $dreplacements[3]='';
   if ($cdata!='hide') {
    $dpatterns[4]="/<\!\[CDATA\[(.+)\]\]>/sU"; $dreplacements[4]='$1';
   else {
    $dpatterns[4]="/<\!\[CDATA\[(.+)\]\]>/sU"; $dreplacements[4]='';
   <dt><a href=\"$link\">$title</a></dt>
   <dd class=\"story\">$description</dd>
   <dd>Date: $date</dd>\r";
return $theData;



Here's some HTML with PHP

<?php echo $bbc; ?>
<?php echo $cnn; ?>
<?php echo $flickr; ?>

Here's what we get... (the lastest feeds from the BBC, CNN, and flickr).

Sorry, I'm new to this stuff, willing to learn and all that, but I don't get the idea. Copy that snippet of PHP code into a file and call it, say, parser.php. Copy the other snippet of HTML into a file and call it, for lack of inventiveness, parser.html. Right so far? If so, where's the intermediate step? How does this HTML "call" or "include" the PHP in order to function? Or am I missing something so basic that even asking this will earn me the cherished "Idiot of the Day Award"? Thanks.

2007-03-02 BonRouge says :

You can include the php or just have it in one page. The page would have a '.php' extension - not '.html.'
Here's a simple example of this page (with no style or anthing) in one file.
Save it and change the extension to '.php'. If you don't have a server installed on your machine, you'll have to upload it to a remote server to view it.
If you want, you can take the php code out of that page and save it in a different file and include it into the page - that way, you could use it on more than one page if you wanted.

I hope that makes it a bit clearer.

2007-03-02 dumb_dave says :

Thanks for the explanations. Much clearer now and ... yes, it indeed works like a champ. (Maybe I was just too tired? Putting 1 and 1 together and coming up with 11 instead of two?) Best regards and thanks for all the tips elsewhere as well.

2007-03-07 dumb_dave says :

Useful indeed, BonRouge, but how does one display the <description> tagged material that is buried behind things like <![CDATA[ <p> etc.? Is the PHP code easily modified to handle that? And if so, can one apply it selectively? That is, show the fuller "description" material for one site but then reduce the next site entry to "headines" only (i.e., "titles" and "links") and then toggle the next one back to fuller details? Hope this is not a major headache, but it's beyond my ability to work it out at this stage ... and everything tried brought the larger process to a grinding halt. (This isn't a do-my-homework-for-me question. I'm bewildered by the code.) Thanks.

2007-03-07 BonRouge says :

I thought I'd already sorted out the problem of data wrapped in the CDATA stuff. Does the code have a problem? If you could show me where it's not working, I'll try to improve it.
As for choosing whether to show that particular data or not, yes - I think you could do that by adding another variable. You see near the top where there's a preg_replace() to remove the CDATA tags? You could put that in an if statement - if the variable is not present, remove the CDATA tags, if it is, leave them where they are.
Does that make sense?

2007-03-10 BonRouge says :

I think I found the problem and sorted it out. As you can see, it seems to work OK now. Some of the characters in the Lockergnome feed don't show right on this page though. I wonder if it's anything to do with me being in Japan. Do you see strange characters?

2007-05-01 Ice says :

I have been trawling the web for days looking for something like this. Thanks a WHOLE lot man. I was also wondering if you can modify this parser to merge these fields and display, say, only the latest 10 items? wine

2007-11-02 steve says :

thanks sorted out my cdata parasing problem, seems that is not too clear in the docs
