从wordpress文章中拉出列表

问题描述

我想从我的wordpress文章中取出列表(ul)元素,这样我就可以将它放在不同的位置。



我当前的CSS拉出图像和blockqute并放置文本

html

  <?php 
$ content = preg_replace('/< blockquote>(。*?)< \ / blockquote> /','',get_the_content());
$ content = preg_replace('/(< img [^> *>)/','',$ content);
$ content = wpautop($ content); //添加段落标签
$ content = str_replace('< p>< / p>','',$ content); //删除空白段落
echo $ content;
?>


解决方案

只是一个友好的提示是它通常不被推荐用正则表达式解析html。
如果你想这样做,你可以尝试像这样:

  $ pattern ='〜< ul> ;(。*?)< / UL>〜S'; 

所以在你的代码中它看起来像这样:

  preg_match_all('/(〜< ul>(。*?)< / ul>〜s)/',$ content,$ ulElements); 

然后将其从原始字符串中移除:

  preg_replace('/(〜
    (。*?)< / ul>〜s)/','',$ content);


I want to pull out the list (ul) element from my wordpress post(s) so I can put it in a different location.

My current css pulls out the images and blockqute and puts just the text

html

<?php
  $content = preg_replace('/<blockquote>(.*?)<\/blockquote>/', '', get_the_content());
  $content = preg_replace('/(<img [^>]*>)/', '', $content);
  $content = wpautop($content); // Add paragraph-tags
  $content = str_replace('<p></p>', '', $content); // remove empty paragraphs
    echo $content;
?>
解决方案

Just a friendly reminder is that it is generally not recommended to parse html with regex.If you would like to do that anyway you could try like this:

$pattern = '~<ul>(.*?)</ul>~s';

So in your code it would look like this:

preg_match_all('/(~<ul>(.*?)</ul>~s)/', $content, $ulElements);

And then for removing it from the original string:

preg_replace('/(~<ul>(.*?)</ul>~s)/', '', $content);
