Close or Fix a broken img tag using PHP

问题

I'm having troubles fixing a 'broken' html string, using PHP

I'm facing the common problem of using substr on an html string, which results in broken tags.

I've managed to fix all the broken tags, except the image one, as the tag itself is not complete, it's not even an opening tag,

For example, Suppose you have a string:

<div><img alt="foo" title="bar"

I'd really want to to add a > to close this, and my other scripts know how to close the div automatically.

Does anyone have any ideas on how to catch broken <img> tags and automatically fix them?

I've seen many solutions including DOMdocument, tidy and HTMLpurifier, but they don't seem to fix this specific problem.

Any help would be appreciated.

回答1:

Yes you can repair tags using DOMDocument. (Based on example):

$html = '<div><img alt="foo" title="bar"';
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML($html);
libxml_clear_errors();

$out = '';
foreach ($dom->getElementsByTagName('body')->item(0)->childNodes as $child) {
    $out .= $dom->saveXML($child);
}
echo htmlentities($out);
