[英]Get text with PHP Simple HTML DOM Parser
i'm using PHP Simple HTML DOM Parser to get text from a webpage.我正在使用 PHP Simple HTML DOM Parser 从网页中获取文本。 The page i need to manipulate is something like:我需要操作的页面是这样的:
<html>
<head>
<title>title</title>
<body>
<div id="content">
<h1>HELLO</h1>
Hello, world!
</div>
</body>
</html>
I need to get the h1
element and the text that has no tags.我需要获取h1
元素和没有标签的文本。 to get the h1
i use this code:要获得h1
我使用以下代码:
$html = file_get_html("remote_page.html");
foreach($html->find('#content') as $text){
echo "H1: ".$text->find('h1', 0)->plaintext;
}
But the other text?但是其他文字呢? I also tried this into the foreach but i get the full text:我也在 foreach 中尝试过这个,但我得到了全文:
$text->plaintext;
but it returned also the H1
tag...但它也返回了H1
标签......
You can simply strip html tags using strip_tags
您可以使用strip_tags
简单地strip_tags
html 标签
<?php
strip_tags($input, '<br>');
?>
Use strip tags, as @Peachy pointed out.正如@Peachy 指出的那样,使用条带标签。 However, passing it a second argument <br>
means string will ignore <br>
tags, which is unnecessary.但是,向它传递第二个参数<br>
意味着 string 将忽略<br>
标签,这是不必要的。 In your case,在你的情况下,
<?php
strip_tags($text);
?>
would work as you'd like, given that you are only selecting content in the content
id.可以按您的意愿工作,因为您只选择content
ID 中的content
。
尝试一下
echo "H1: ".$text->find('h1', 0)->innertext;
It looks like $text->find('text',2);
它看起来像$text->find('text',2);
gets what you're looking for, however I'm not sure how well that will work when the amount of text nodes is unknown.得到你正在寻找的东西,但是我不确定当文本节点的数量未知时它会如何工作。 I'll keep looking.我会继续寻找。
