php - 使用正则表达式（或任何其他方式）匹配基本 HTML

Question

我有一些HTML如下：

    <b>This is a title: </b> 0091 + Two + 423 + Four + (Five, Six, Seven)
    <b>Some more text: </b> Abc + Hi + Random + Text + (Hello, 522, Four)
    ...
    <b>Hello world!: </b> Test + Foo + 1122 + (120, 122, Four)

现在，使用php，我想拆分它并制作两个数组，如下所示：

数组 1 - （这将包含<b>标签中的所有内容）

    [0] -> <b>This is a title: </b>
    [1] -> <b>Some more text: </b>
    ...
    [n] -> <b>Hello world!: </b>

数组 2 - （这将包含标签之外的所有内容）<b>

    [0] -> 0091 + Two + 423 + Four + (Five, Six, Seven)
    [1] -> Abc + Hi + Random + Text + (Hello, 522, Four)
    ...
    [n] -> Test + Foo + 1122 + (120, 122, Four)

我尝试使用正则表达式，preg_match_all但我似乎无法弄清楚它们。任何帮助将不胜感激。

谢谢！

Answer 1

<?php 
$string = '    <b>This is a title: </b> 0091 + Two + 423 + Four + (Five, Six, Seven)
    <b>Some more text: </b> Abc + Hi + Random + Text + (Hello, 522, Four)
    ...
    <b>Hello world!: </b> Test + Foo + 1122 + (120, 122, Four)';
preg_match_all("#(<b>[^<]+<\/b>)([^<]+)#", $string, $matches);
print_r($matches);
?> 

输出：

Array
(
    [0] => Array
        (
            [0] => <b>This is a title: </b> 0091 + Two + 423 + Four + (Five, Six, Seven)

            [1] => <b>Some more text: </b> Abc + Hi + Random + Text + (Hello, 522, Four)
    ...

            [2] => <b>Hello world!: </b> Test + Foo + 1122 + (120, 122, Four)
        )

    [1] => Array
        (
            [0] => <b>This is a title: </b>
            [1] => <b>Some more text: </b>
            [2] => <b>Hello world!: </b>
        )

    [2] => Array
        (
            [0] =>  0091 + Two + 423 + Four + (Five, Six, Seven)

            [1] =>  Abc + Hi + Random + Text + (Hello, 522, Four)
    ...

            [2] =>  Test + Foo + 1122 + (120, 122, Four)
        )

)

Answer 2

你可以试试这个：

<pre>
<?php

$subject =<<<LOD
<b>This is a title: </b> 0091 + Two + 423 + Four + (Five, Six, Seven)
<b>Some more text: </b> Abc + Hi + Random + Text + (Hello, 522, Four)
<b>Hello world!: </b> Test + Foo + 1122 + (120, 122, Four)
LOD;

$pattern = '~(<b>.*?</b>)((?>[^<]+|<(?!b))*)~';
preg_match_all($pattern, $subject, $matches);

array_shift($matches);
array_walk_recursive($matches,function (&$val){ $val=trim($val); });
list($array1, $array2) = $matches;

print_r($array1);
print_r($array2);
