如何在多个<title>标签</title>之间获取所有内容

Question

我想在这个网站的标题标签之间获得多个标题：

http://drewgarcia23.3owl.com/LiveScores/mlb.php

我尝试过simplexml方式。但这可能是愚蠢的，因为它是一个php文件。任何帮助将不胜感激。我也尝试过preg匹配标签并剥离标签并获取错误。感到沮丧，所以我发布这个。 编码不好

$url = 'http://drewgarcia23.3owl.com/LiveScores/mlb.php';
$rss = simplexml_load_file($url);
$items = $rss->channel->item;
echo $items;

Answer 1

simplexml_load_file()函数将XML文件解释为对象。

这是一个生成xml的php文件。所以：

$url = 'http://drewgarcia23.3owl.com/LiveScores/mlb.php';
$items = simplexml_load_file($url);

foreach ($items->channel->item as $item) {
    echo $item->title . "<br>";
}

标题输出成功。

NY Mets 5 Atlanta 2 (FINAL)
Minnesota 5 Houston 6 (FINAL)
Miami 7 Chicago Cubs 9 (FINAL)
...

Answer 2

试试这个正则表达式：

/<title>(.+)<\/title>/i

preg_match_all('/<title>(.+)<\/title>/i', '{{your data}}', $arr, PREG_PATTERN_ORDER);

Array
(
    [0] => Array
        (
            [0] => <title>MLB Scores</title>
