使用正则表达式替换内部链接，但如果它们是动态的，则不是，即包含php回显

Question

I am going through a project and replacing internal links to go through a url function. I have created a bit of regex which does what I need, however I don't want it to do anything with dynamic links, as I'm going to go through and do them manually.

My regex is:

(href|src)=(?:'|")\/(?!http)(.+?)(?:'|")

My replace is:

$1="<?php echo url('$2'); ?>"

This works fine for:

<link rel='stylesheet' type='text/css' href='/public/css/print.css' media="print"/>
<link rel='stylesheet' type='text/css' href='http://example.com/public/css/print.css' media="print"/>

I want it to ignore the following though:

<link rel='stylesheet' type='text/css' href='/public/css/print<?php echo 1; ?>.css' media="print"/>

Bonus points if someone can provide a seperate regex and replace which takes the echo and places it in a string concatination of the url function! Something along the lines of

$1="<?php echo url('$2' . $3 . '$4'); ?>"

Answer 1

(?:'|")\/(?!http)([^<]+?)(?:'|")

will probably be good enough for the first part. Ie, replace the . with [^<] to match only strings that don't contain an opening angle bracket.

This might work ok for the second part

(?:'|")\/(?!http)([^<]+?)(<\?php[^>]*?>)?([^<]+?)(?:'|")
