[PHP] XML Feed

[Necro]

I am currently trying to implement XML Parsing on a site using the XML News
Feed of another site. The site puts two versions of the news in its file
though:

- item
  titleTsunami 2265 Date, Demo/title
  linkhttp://www.shacknews.com/onearticle.x/20959/link
  /item

- ITEM
  SUBJECTTsunami 2265 Date, Demo/SUBJECT
  URLhttp://www.shacknews.com/onearticle.x/20959/URL
  CATEGORYGeneral/CATEGORY
  /ITEM

I have a script that is meant to parse the file which is downloaded to a
local file hourly. The trouble is that the script tries parsing both lots
and I only wish it to parse the top half and to stop when it reaches the
entries using SUBJECT tags.

Does anyone have a solution for this? The script below is what I use to echo
the news onto my site. The script attached is the script that is meant to
parse the xml document.

?  include( includes/xmlfeed.php );
$rdffile = shacknews.xml;
$remote = http://www.shacknews.com/shackfeed.xml;;
$refreshtime = time() - 3600;
?

?
if ((filemtime($rdffile)  $refreshtime) || (filesize($rdffile) == 0)) {
$RDF = fopen( $rdffile, w ) or die( Cannot open $rdffile );
$FILE = fopen( $remote, r ) or die( Cannot open $remote );
while (!feof( $FILE )) {
fwrite( $RDF, fgets( $FILE, 1024 ));
}
fclose( $RDF );
fclose( $FILE );
}

parseRDF( $rdffile );
?

Man, that's REALLY bad XML.

 local file hourly. The trouble is that the script tries parsing both lots
 and I only wish it to parse the top half and to stop when it reaches the
 entries using SUBJECT tags.

I'd stop when it hits the ending /item tag.

Take a look at http://www.analysisandsolutions.com/code/phpxml.htm.  For 
your case, in the EndHandler() function, put in the case 'ITEM'  In that 
case, have the code process the data you've accumulated and exit.


But, if you want to stick with your methodology, below, here's a 
possibility:


if ((filemtime($rdffile)  $refreshtime) || (filesize($rdffile) == 0)) {
   $RDF = fopen( $rdffile, 'w' ) or die( Cannot open $rdffile );
   $FILE = fopen( $remote, 'r' ) or die( Cannot open $remote );

   while (!feof( $FILE )) {
  $Line = fgets( $FILE, 1024 );
  fwrite( $RDF, $Line);
  if ( preg_match('/\/item/', $Line) ) {
 break;
  }
   }

   fclose( $RDF );
   fclose( $FILE );
}
