PHP中的XML（RSS阅读器）

Question

I have this code and it works great

$i = 0; // counter
$url = "http://www.banki.ru/xml/news.rss"; // example url to parse
$rss = simplexml_load_file($url); // XML parser
print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src

foreach($rss->channel->item as $item) {
if ($i < 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

$i++;
}

But I would like to show only second item from this feed. How I can do this?

Answer 1

Change this

if ($i < 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

to

if ($i == 1) { // parse only 1 item
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}

Answer 2

try:

$i = 0; // counter
$url = "http://www.banki.ru/xml/news.rss"; // example url to parse
$rss = simplexml_load_file($url); // XML parser
print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src

print '<a href="'.$rss->channel->item[1]->link.'">'.$rss->channel->item[1]->title.'</a><br />';

Answer 3

Just change the if condition it will get you the second session

 <?php $i = 0; // counter $url = "http://www.banki.ru/xml/news.rss"; // example url to parse $rss = simplexml_load_file($url); // XML parser print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src foreach($rss->channel->item as $item) { if ($i > 1) { // parse only 1 item print '<a href="'.$item->link.'">'.$item->title.'</a><br />'; } $i++; }
