Answer 1

此regex适用于给定的字符串。

Search for   - "([^<>]*?)"(?=[^>]*?<)
Replace with - &raquo;\1&laquo;

在这里演示
测试它-

INPUT - 
<p>This is a "wonderful long text". "Another wonderful ong text" At least it should be. Here we have a <a href="http://wwww.site-to-nowhere.com" target="_blank">link</a>.</p>

OUTPUT - 
<p>This is a &raquo;wonderful long text&laquo;. &raquo;Another wonderful ong text&laquo; At least it should be. Here we have a <a href="http://wwww.site-to-nowhere.com" target="_blank">link</a>.</p>

在PHP中执行此操作-

$str = '<p>This is a "wonderful long text". "Another wonderful ong text" At least it should be. Here we have a <a href="http://wwww.site-to-nowhere.com" target="_blank">link</a>.</p>';
var_dump(preg_replace('/"([^<>]*?)"(?=[^>]*?<)/', '&raquo;\1&laquo', $str));

是输出-

/** OUTPUT **/
string '<p>This is a &raquo;wonderful long text&laquo. &raquo;Another wonderful ong text&laquo At least it should be. Here we have a <a href="http://wwww.site-to-nowhere.com" target="_blank">link</a>.</p>' (length=196)

echo '»\1«';
echo "»\1«";

preg_replace('/"([^<>]*?)"(?=[^>]*?<)/', '&raquo;\1&laquo;', $str)
preg_replace("/\"([^<>]*?)\"(?=[^>]*?<)/", "&raquo;\\1&laquo;", $str)
preg_replace("/\"([^<>]*?)\"(?=[^>]*?<)/", "&raquo;$1&laquo;", $str)

\"([^<>]*?)\"(?=(?:[^>]*?(?:<|$)))
