如何在没有结束标签的自定义动态 html 标签之间获取文本

Question

我有由多个自定义标签分隔的文本，这些标签具有部分动态名称且没有结束标签。

我需要的是获取文本的所有单独部分在自定义标签之间，不包括标签。

对于文本的最后一部分，我只能在标签之后获取文本，因为它没有结束标签。

我见过很多类似的问题，但我发现它们不足以解决我的问题。

例子：

<*fixedTagName|Dynamic part of tag name> // * and | are included in fixed part of tag name
                                   //dynamic part can have spaces between words

  Random text I need to get of unknown length

  some paragraphs of text can start like this(look bellow)

  » name: value
  » name: value

<*fixedTagName|Dynamic part of tag>

  More random text I need to get

<*fixedTagName|Dynamic part of tag>

  Final part of random text I need to get

要获取正则表达式匹配之间的文本，您可以使用 preg_split 函数：

$result = preg_split('/<\*[^|]+\|[^>]+>/', $input);

在这个正则表达式中：

• <\* 匹配 <*;
• [^|]+ 匹配除 | 之外的任何符号 1..* 次；
• \| 匹配 |;
• [^>]+ 匹配除 > 之外的任何符号 1..* 次；
• > 匹配 >。

有了这个输入：

$input = <<<EOL
<*fixedTagName|Dynamic part of tag name> // * and | are included in fixed part of tag name
                                   //dynamic part can have spaces between words

  Random text I need to get of unknown length

  some paragraphs of text can start like this(look bellow)

  » name: value
  » name: value

<*fixedTagName|Dynamic part of tag>

  More random text I need to get

<*fixedTagName|Dynamic part of tag>

  Final part of random text I need to get
EOL;

$result 将是一个类似这样的字符串数组：

Array
(
    [0] => 
    [1] =>  // * and | are included in fixed part of tag name
                                   //dynamic part can have spaces between words

  Random text I need to get of unknown length

  some paragraphs of text can start like this(look bellow)

  » name: value
  » name: value


    [2] => 

  More random text I need to get


    [3] => 

  Final part of random text I need to get
)
