更确切地说,我需要能够像这个脚本那样剥离HTML标签:zubrag.com/tools/html-tags-stripper.php
我需要能够在我的localhost(xampp服务器)上使用任何url执行此操作,但是现在我想使用此url来删除标记,因为它最容易获得:{{3} }
我有什么,不起作用,我不知道为什么或如何解决它。 以下是代码来自:nadeausoftware.com/articles/2007/09/php_tip_how_strip_html_tags_web_page
我已将此行添加到代码中,但它仍无效...
$text = file_get_contents('http://static.anaf.ro/static/10/Timis/Timis.htm');
下面是原始代码(注意原始代码没有上面的那行。那条线是我添加的)

答案 0 :(得分:1)
它运行正常,但是帖子中链接的正则表达式不起作用。它没有返回正确的字符集,所以试试这个:
function strip_html_tags( $text )
{
$text = preg_replace(
array(
// Remove invisible content
'@<head[^>]*?>.*?</head>@siu',
'@<style[^>]*?>.*?</style>@siu',
'@<script[^>]*?.*?</script>@siu',
'@<object[^>]*?.*?</object>@siu',
'@<embed[^>]*?.*?</embed>@siu',
'@<applet[^>]*?.*?</applet>@siu',
'@<noframes[^>]*?.*?</noframes>@siu',
'@<noscript[^>]*?.*?</noscript>@siu',
'@<noembed[^>]*?.*?</noembed>@siu',
// Add line breaks before and after blocks
'@</?((address)|(blockquote)|(center)|(del))@iu',
'@</?((div)|(h[1-9])|(ins)|(isindex)|(p)|(pre))@iu',
'@</?((dir)|(dl)|(dt)|(dd)|(li)|(menu)|(ol)|(ul))@iu',
'@</?((table)|(th)|(td)|(caption))@iu',
'@</?((form)|(button)|(fieldset)|(legend)|(input))@iu',
'@</?((label)|(select)|(optgroup)|(option)|(textarea))@iu',
'@</?((frameset)|(frame)|(iframe))@iu',
),
array(
' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ',
"\n\$0", "\n\$0", "\n\$0", "\n\$0", "\n\$0", "\n\$0",
"\n\$0", "\n\$0",
),
$text );
return strip_tags( $text );
}
/* Read an HTML file */
$raw_text = file_get_contents('http://static.anaf.ro/static/10/Timis/Timis.htm');
/* Get the file's character encoding from a <meta> tag */
preg_match("/<meta[^>]+charset=['\"]?(.*?)['\"]?[\/\s>]/i", $raw_text, $matches );
$encoding = $matches[1];
/* Convert to UTF-8 before doing anything else */
$utf8_text = iconv( $encoding, "utf-8", $raw_text );
/* Strip HTML tags and invisible text */
$utf8_text = strip_html_tags( $utf8_text );
/* Decode HTML entities */
$utf8_text = html_entity_decode( $utf8_text, ENT_QUOTES, "UTF-8" );
echo $utf8_text;
我改变了什么:
要获得正确的字符集,我只需更换此
/* Get the file's character encoding from a <meta> tag */
preg_match( '@<meta\s+http-equiv="Content-Type"\s+content="([\w/]+)(;\s+charset=([^\s"]+))?@i', $raw_text, $matches );
$encoding = $matches[3];
用这个
preg_match("/<meta[^>]+charset=['\"]?(.*?)['\"]?[\/\s>]/i", $raw_text, $matches );
$encoding = $matches[1];
编辑1: 猜猜网站上的脚本在从您提供的URL中剥离标记时遇到了一些问题。它显示了很多。我想剥离标签的最好方法就是在开口之间剥离所有东西。和第一次结束&gt;。但我目前对正则表达式一无所知,也许谷歌可以提供帮助:)
