为什么这个PHP代码段不起作用？

Question

In localhost (using Wamp on windows). I'm trying to use this:

<?
$xml = simplexml_load_file(‘http://stocklamp.tumblr.com/api/read/xml’);
$posts = $xml->xpath(“/tumblr/posts/post[@type=’regular’]”);
foreach($posts as $post) {?>  
<?echo $post[‘id’];?>
<?echo $post[‘url-with-slug’];?>”>
<?echo $post->{‘regular-title’};?>
<?echo $post->{‘regular-body’};?>
<?echo date(“jS D M, H:i”,strtotime($post[‘date’]));?>
<?}?>

When trying, all I see is this on my site:

xpath(“/tumblr/posts/post[@type=’regular’]”); foreach($posts as $post) { ?> ”> {‘regular-title’};?> {‘regular-body’};?>

I found the snippet here:

http://stocklamp.tumblr.com/post/274675902/putting-your-tumblr-posts-on-your-websites-the-easy-way

Edit: fixed. Now I'm getting

Parse error: syntax error, unexpected ':' in C:\wamp\www..\index.php on line 52

and it is this line:

$xml = simplexml_load_file(‘http://stocklamp.tumblr.com/api/read/xml’);

I keep getting this error: http://codepad.org/7f1IejIG

Okay. Now I go that fixed, but how do I get the posts by tag?

changing 'type=...' doesn't work.

$posts = $xml->xpath("/tumblr/posts/post[@type='file']");

Answer 1

The last problem is to resolve is that the API XML url provided on the blog is not right. The following works:

<?php
$xml = simplexml_load_file('http://stocklamp.tumblr.com/api/read/'); // No /xml
$posts = $xml->xpath('/tumblr/posts/post[@type="regular"]');
foreach($posts as $post) {?>  
<?echo $post['id'];?>
<?echo $post['url-with-slug'];?>”>
<?echo $post->{'regular-title'};?>
<?echo $post->{'regular-body'};?>
<?echo date("jS D M, H:i",strtotime($post['date']));?>
<?}?>

EDIT

Try running this code without the tags interspersed:

<?php
$xml = simplexml_load_file('http://stocklamp.tumblr.com/api/read/'); // No /xml
$posts = $xml->xpath('/tumblr/posts/post[@type="regular"]');
foreach($posts as $post) {  
    echo $post['id'];
    echo $post['url-with-slug'];
    echo $post->{'regular-title'};
    echo $post->{'regular-body'};
    echo date("jS D M, H:i",strtotime($post['date']));
}
?>
