Question

我目前正在使用地理编码解析Twitter推文并使用php显示它们。但目前无法访问推文的URL，而是选择向用户显示Twitter个人资料。

我尝试访问的网址在链接标记

中

<link type="text/html" href="http://twitter.com/pmhigham/statuses/166271863331368961"     rel="alternate" >

它在XML文件中的位置是Feed-＆gt; Entry-＆gt; Link。

我考虑过使用正则表达式，但不知道如何使用它。

这是我的代码。

<h3><?php
if (isset($column1Heading)) {
echo $column1Heading;
}
?></h3>
                <p>
                <strong>Tweets within 10 miles radius of London Eye</strong></br>
              <?php 
               $feed = simplexml_load_file ('http://search.twitter.com/search.atom?geocode=51.5069999695%2C-0.142489999533%2C10.0mi%22london%22&lang=en&rpp=5');
                if ($feed){foreach ($feed->entry as $item) {

                      echo '<a href=\'' . $item->author->uri. '\'>' . $item->title . '</a>', '</br>' . $item->published, '</br>';
                }
                }
                else echo "Cannot find Twitter feed!"
                ?>
                </br>
               <strong>London Hashtag</strong>

                if ($feed){foreach ($feed->entry as $item) {

                }
                }
                else echo "Cannot find Twitter feed!"

Answer 1

如果我理解正确的话：

您可以使用SimpleXML内置的attributes() method访问该属性。

$item->link->attributes()->href

否则正则表达式应如下所示

$string = '<link type="text/html" href="http://twitter.com/pmhigham/statuses/166271863331368961"     rel="alternate" >';
preg_match('/href\=\"([^\"]+)\"/i', $string, $matches);

访问Twitter XML标记内的URL
