问题描述
我在基本上是div列表的字符串中有一个html块...每个div里面都有要单独解析的html.
I have a block of html in a string that is basically a list of divs... Each div has html inside that I want to parse seperately.
我在弄清楚如何遍历初始div时遇到麻烦.
I am having trouble figuring out exactly how to loop over the initial divs.
任何人都可以帮忙吗?
html的示例:
<div><!-- stuff in here --></div>
<div><!-- stuff in here --></div>
<div><!-- stuff in here --></div>
<div><!-- stuff in here --></div>
在此示例中，我希望最终代码会循环四次，并为我提供每个div的内容
In this example I would expect the final code to loop round 4 times and provide me with the contents of each div
推荐答案
这应该有效(如果HTML在外部文件中):
This should work (if the HTML is in an external file):
$doc = new DOMDocument();
$doc->loadHTMLFile('test.html');
$divs = $doc->getElementsByTagName('div');
foreach($divs as $n) {
echo $n->nodeValue;
}
如果包含HTML的字符串，则可以执行以下操作:
And in case of a string containing the HTML, you could do:
$doc = new DOMDocument();
$doc->loadHTML('<html><body><div>A</div><div>B</div><div>C</div><div>D</div></body></html>');
$divs = $doc->getElementsByTagName('div');
foreach($divs as $n) {
echo $n->nodeValue . "\n";
}
这将产生:
A
B
C
D
