PHP preg_match_all 重复出现模式

我正在尝试获取开放标签的匹配项。存在打开父标签（包括子标签）的问题。父标签被捕获，但忽略子标签。

前任。

</p>
<p>hello world</p>
<p><img

preg_match_all('/<(\/?[a-z]+)[^>]*\/?>/i', $trimmed_text, $matches, PREG_OFFSET_CAPTURE | PREG_SET_ORDER);

将给出以下输出：

Array
 (
[0] => Array
    (
        [0] => Array
            (
                [0] => 


                [1] => 0
            )

        [1] => Array
            (
                [0] => /p
                [1] => 1
            )

    )

[1] => Array
    (
        [0] => Array
            (
                [0] => 

[1] => 5 ) [1] => Array ( [0] => p [1] => 6 ) ) [2] => Array ( [0] => Array ( [0] =>

                [1] => 19
            )

        [1] => Array
            (
                [0] => /p
                [1] => 20
            )

    )

[3] => Array
    (
        [0] => Array
            (
                [0] => 

 [1] => 24 ) [1] => Array ( [0] => p [1] => 25 ) ) )

父级中任何打开的标签是否有可能拥有子集数组？

原文

I am trying to grab a match of open tags. Having an issue where a parent tag is opened including a child tag. The parent tag is captured but it ignores the children tags.

ex.

</p>
<p>hello world</p>
<p><img

preg_match_all('/<(\/?[a-z]+)[^>]*\/?>/i', $trimmed_text, $matches, PREG_OFFSET_CAPTURE | PREG_SET_ORDER);

would give the following output:

Array
 (
[0] => Array
    (
        [0] => Array
            (
                [0] => 


                [1] => 0
            )

        [1] => Array
            (
                [0] => /p
                [1] => 1
            )

    )

[1] => Array
    (
        [0] => Array
            (
                [0] => 

[1] => 5 ) [1] => Array ( [0] => p [1] => 6 ) ) [2] => Array ( [0] => Array ( [0] =>

                [1] => 19
            )

        [1] => Array
            (
                [0] => /p
                [1] => 20
            )

    )

[3] => Array
    (
        [0] => Array
            (
                [0] => 

 [1] => 24 ) [1] => Array ( [0] => p [1] => 25 ) ) )

Is it possible for any opened tags in a parent to have a subset array?

你做得很困难，使用 PHP Simple HTML DOM Parser 来解析html，

例如：

// Create DOM from URL or file
include('simple_html_dom.php');
$html = file_get_html('http://www.scroogle.org/');

// Find all images
foreach($html->find('img') as $element)
       echo $element->src . '<br>';

// Find all links
foreach($html->find('a') as $element)
       echo $element->href . '<br>';

you're doing it the hard way, use PHP Simple HTML DOM Parser to parse html,

ex:

// Create DOM from URL or file
include('simple_html_dom.php');
$html = file_get_html('http://www.scroogle.org/');

// Find all images
foreach($html->find('img') as $element)
       echo $element->src . '<br>';

// Find all links
foreach($html->find('a') as $element)
       echo $element->href . '<br>';
