上面那个正则表达式匹配的问题解决了

Jun 23, 2016 pm 02:25 PM

找到原因了,但是原帖无法回复,也无法修改

总结一下吧:
想匹配一个网页地址中的所有图像地址,写了正则表达式如下:

$reg="/<img  src="/static/imghw/default1.png"  data-src="../Images/Album Cover/album_012.jpg"  class="lazy" \s*.*src\s*=\s*[\"|\']?\s*([^ alt="上面那个正则表达式匹配的问题解决了" >\"\']*)/i";
Copy after login

为什么像如下的图像文件地址:
<img  src="/static/imghw/default1.png"  data-src="../Images/Album Cover/album_012.jpg"  class="lazy"   alt="上面那个正则表达式匹配的问题解决了" >
Copy after login

只能匹配到:
上面那个正则表达式匹配的问题解决了$reg="/<img  src="/static/imghw/default1.png"  data-src="../Images/Album Cover/album_012.jpg"  class="lazy" \s*.*src\s*=\s*[\"|\']?\s*([^ alt="上面那个正则表达式匹配的问题解决了" >\"\']*)/i";$s = '<img  src="/static/imghw/default1.png"  data-src="../Images/Album Cover/album_012.jpg"  class="lazy"   alt="上面那个正则表达式匹配的问题解决了" >';preg_match_all($reg, $s, $m);print_r($m);
Copy after login


运行后输出:
Array(    [0] => Array        (            [0] => 
Copy after login


chrome把后面的
<img  src="../Images/Album Cover/album_012.jpg        )    [1] = alt="上面那个正则表达式匹配的问题解决了" > Array        (            [0] => ../Images/Album Cover/album_012.jpg        ))
Copy after login

全删掉了!而且是在源代码中,也就是看最后的网页源代码也看不到这一段!换了firefox,上面的这段直接在网页上也看不到,看源代码可以找到这一段,而且是用红色标记的,这果断是逼我换firefox嘛?

....
echo '

';  <br> print_r($m);  <p class="sougouAnswer">  ....  <br> echo '</p><pre class="brush:php;toolbar:false">';  <br> print_r($m);  <br> 加了<pre class="brush:php;toolbar:false">的,就是输出上面那个结果,应该是chrome的安全保护措施吧,把结果中的不良代码删掉了,不信你可以换个chrome试试,我的chrome版本是 29.0.1541.0  <br>  <br> 果断换firefox了  <p class="sougouAnswer">  试了下,好像是那么回事。那就用firefox吧。 </p>
