PHP解析无效的HTML [英] PHP parsing invalid html

问题描述

我正在尝试解析服务器上不存在的html

i'm trying to parse some html that is not on my server

    $dom = new DOMDocument();
    $dom->loadHTMLfile("http://www.some-site.org/page.aspx");      
    echo    $dom->getElementById('his_id')->item(0);

但是php返回类似ID his_id already defined in http://www.some-site.org/page.aspx, line: 33的错误.我认为这是因为DOMDocument正在处理无效的html.那么，即使无效，我该如何解析呢?

but php returns an error something like ID his_id already defined in http://www.some-site.org/page.aspx, line: 33. I think that is because DOMDocument is dealing with invalid html. So, how can i parse it even though is invalid?

推荐答案

您应运行 HTML对其进行整理，以便在解析之前对其进行清理.

You should run HTML Tidy on it to clean it up before parsing it.

$html = file_get_contents('http://www.some-site.org/page.aspx');
$config = array(
  'clean' => 'yes',
  'output-html' => 'yes',
);
$tidy = tidy_parse_string($html, $config, 'utf8');
$tidy->cleanRepair();
$dom = new DOMDocument;
$dom->loadHTML($tidy);

请参见此选项列表.
