正则表达式梦Night [英] Regular Expression Nightmare

问题描述

大家好，
我似乎可以解决这个reg-ex，任何帮助将不胜感激，
我想将搜索到的单词替换为HREF，但要避免HREF嵌套，我现在正在做的事情是，我在开始和结束处放置了垃圾``< ##''和``##>"已更改的文本中搜索到的单词中的单词，然后替换不在< ##和##>
之间的单词

Hello Guys,
there is this reg-ex that i can seem to solve, any help would be appreciated,
i wana replace the searched word into an HREF,but avoid the nesting of HREFs, what im doin rite now, is that i place garbage ''<##'' and ''##>'' in the begining and end of the searched word in the text that has already been changed and then replace the words not in between <## and ##>

// placing <## and ##> 
$temptext = preg_replace('/(<a([^>]+)>)(.*?)(<\/a>)/is', "$1<##$3##>$4", $blogvalue["content"]);

//then search the word not in <## and ##>

$search = "/([^<##a-zA-Z'=:\"]".mysql_escape_string($value["keyword"]).")/is";

// replace it with the HREF

$replace = ' <a href="'.$value[" url="].'">'.mysql_escape_string($value["keyword"]).'</a>';

//assign it to the new content
$newContent = preg_replace($search, $replace, $temptext);

现在的问题是，这也改变了HREF内部的链接，
例如，如果我的内容中的某些链接已经更改，例如
< a href ="www.brown.com">布朗</a>我想更改内容中其余的棕色"，它会忽略锚点内的棕色"，但会更改www.brown.com中的棕色" ...

任何想法

[修改:添加了前置标记，尽管我不确定这是什么语言... $使我想到了PHP，但没有以//开头的注释.

now the problem is that this also changes the link inside the HREF,
for example, if i have some link already changed in my content like
<a href="www.brown.com">Brown</a> and i wana change the rest of the ''Brown'' in the content, it would ignore the ''Brown'' inside the anchors, but would change the ''brown'' in www.brown.com .....

any ideas

[Modified: added pre tags, though I''m not sure what language that is...the $ made me think PHP, but not with comments starting with //]

推荐答案

temptext = preg_replace(' /(< a([^>] +)>)()( .*?)(< \/a>)/是'，"

temptext = preg_replace('/(<a([^>]+)>)(.*?)(<\/a>)/is', "

1< ##

3 ##>
