regex php:在div中查找所有内容 [英] regex php: find everything in div
问题描述
我正在尝试使用regexp在div内查找eveything.我知道可能有一种更聪明的方法来执行此操作-但我选择了regexp.
I'm trying to find eveything inside a div using regexp. I'm aware that there probably is a smarter way to do this - but I've chosen regexp.
所以目前我的正则表达式模式如下:
so currently my regexp pattern looks like this:
$gallery_pattern = '/<div class="gallery">([\s\S]*)<\/div>/';
它可以解决问题-
问题是如果我彼此之间有两个div，就像这样.
The problem is if i have two divs after each other - like this.
<div class="gallery">text to extract here</div>
<div class="gallery">text to extract from here as well</div>
我想从两个div中提取信息，但是在测试时，我的问题是我没有得到中间的文本，而是:
I want to extract the information from both divs, but my problem, when testing, is that im not getting the text in between as a result but instead:
"text to extract here </div>
<div class="gallery">text to extract from here as well"
所以总结一下.它跳过div的第一端.并继续进行下一个.
div中的文本可以包含<，/和换行符.只是让您知道！
So to sum up. It skips the first end of the div. and continues on to the next.
The text inside the div can contain <, / and linebreaks. just so you know!
有人对这个问题有简单的解决方案吗?我仍然是正则表达式新手.
Does anyone have a simple solution to this problem? Im still a regexp novice.
推荐答案
这样的事情怎么样:
$str = <<<HTML
<div class="gallery">text to extract here</div>
<div class="gallery">text to extract from here as well</div>
HTML;
$matches = array();
preg_match_all('#<div[^>]*>(.*?)</div>#', $str, $matches);
var_dump($matches[1]);
注意?"在正则表达式中，因此它不是贪婪的".
Note the '?' in the regex, so it is "not greedy".
哪位可以帮助您:
array
0 => string 'text to extract here' (length=20)
1 => string 'text to extract from here as well' (length=33)
这应该可以正常工作...如果您没有divs的话；如果您这样做了……那么……实际上:您真的确定要使用有理表达式来解析HTML，这本身并不是那个有理吗?
This should work fine... If you don't have imbricated divs ; if you do... Well... actually : are you really sure you want to use rational expressions to parse HTML, which is quite not that rational itself ?
