This script is meant to pull 4 <content> tags from an external page and echo the values. However, it seems to echo all of the <content> tag values but I don't understand why my counter loop is not working.

 

<?php

		$reader = new XMLReader;
		$res = $reader->open('http://www.blogger.com/feeds/17146895/posts/default');
		$entry = false;


for ($i=1; $i<=4; $i++){

while ($reader->read()) {
		if ($reader->name == 'entry') {
 			   if ($reader->nodeType == XMLReader::ELEMENT) {
 				  $entry = true;
   			 } else {
   	 			$entry = false;
 				   }
  		 }




		if ($entry && ($reader->name == 'content')) {

				$reader->read();
   			 if (($reader->name == '#text') && $reader->hasValue) {
   					echo '<p>' . $reader->value . '</p>';

			 }


		}	
		} 

}

?>

Because the contents of the for is pulling out the whole lot, and then you're just repeating that 4 times.

 

Without more info on the XMLReader class you're using, I can't advise how to fix.

What's the XMLReader class? Sorry - I'm a noob!

this is my solution, which seems to work nicely

 

$reader = new XMLReader;
$res = $reader->open('http://www.blogger.com/feeds/17146895/posts/default');
$entry = false;
$i=1;



	while ($reader->read() && $i<=5) {
			   if ($reader->name == 'entry') {
 				  if ($reader->nodeType == XMLReader::ELEMENT) {
 						 $entry = true;
 						   $i++;
   					 } else {
   	 					$entry = false;
 					   }
  					 }




					if ($entry && ($reader->name == 'content')) {

							$reader->read();
   							 if (($reader->name == '#text') && $reader->hasValue) {
							echo '<p>' . $reader->value . '</p>';

   							 }



			}
	}
