PHP - > preg_match_all爲以下結構<h6>我的標題</h6>一些文字... <h6>另一個標題</h6>更多的文字

Question

，我渴望尋求的解決方案得到這個文本字符串

<h6>First pane</h6> 
... pane content ... 
<h6>Second pane</h6> 
Hi, this is a comment. 
To delete a comment, just log in and view the post's comments. 
There you will have the option to edit 
or delete them. 
<h6>Last pane</h6> 
... last pane content ... 

解析到一個PHP數組。

我需要把它單獨給

1. 
1.0=> First pane 
1.1=> ... pane content ... 

2. 
2.0=> Second pane 
2.1=> Hi, this is a comment. 
    To delete a comment, just log in and view the post's comments. 
    There you will have the option to edit 
    or delete them. 

3. 
3.0=> Last pane 
3.1=> ... last pane content ... 

Answer 1

你的正則表達式應該是這樣的：

/<h6>([^<]+)<\/h6>([^<]+)/im 

如果您運行下面的腳本，你會發現你正在尋找的值在$匹配[1]和$匹配[2]。

$s = "<h6>First pane</h6> 
... pane content ... 
<h6>Second pane</h6> 
Hi, this is a comment. 
To delete a comment, just log in and view the post's comments. 
There you will have the option to edit 
or delete them. 
<h6>Last pane</h6> 
... last pane content .."; 
$r = "/<h6>([^<]+)<\/h6>([^<]+)/im"; 

$matches = array(); 
preg_match_all($r,$s,$matches); 

print_r($matches); 

Answer 2

你不應該試圖用正則表達式解析HTML。這注定會給除最簡單的HTML之外的所有人造成很大的痛苦和不快，並且如果文檔結構中的任何內容發生更改，它將立即中斷。使用正確的HTML或DOM解析器來代替，如PHP的DOMDocumenthttp://php.net/manual/en/class.domdocument.php

例如，你可以使用的getElementsByTagName http://www.php.net/manual/en/domdocument.getelementsbytagname.php來獲取所有h6的

Answer 3

我相信PREG_SET_ORDER標誌是你在找什麼。

$regex = '~<h6>([^<]+)</h6>\s*([^<]+)~i'; 

preg_match_all($regex, $source, $matches, PREG_SET_ORDER); 

這種方式，在每個$元素相匹配陣列是包含總體匹配，隨後所有的組的陣列捕捉單個匹配嘗試。結果直到第一場比賽看起來是這樣的：

Array 
(
    [0] => Array 
     (
      [0] => First pane 
... pane content ... 

      [1] => First pane 
      [2] => ... pane content ... 

     )

編輯：請注意\s*我加了。沒有這一點，匹配的內容始終沒有行分隔符開始。
