删除协议时，使用HTTP / S忽略<input>标记

Question

I run a PHP script in WordPress that removes the http: and https: protocols from all the links, this is the full code, but here's the section that strips the protocols:

# If 'Relative' option is selected, remove domain from all internal links
if ( $this->option == 2 ) {
    $website = preg_replace( '|https?:\/\/|', '', home_url() );
    $links = preg_replace( '|https?:\/\/' . $website . '|', '', $links );
}
# For all external links, remove protocols
$links = preg_replace( '|https?:\/\/|', '', $links );

This works as intended. However, it also removes the protocol in text fields like so:

I'm trying to update my regex to ignore any <input> fields so that it doesn't remove protocols. Particularly ones with the value=http: or value=https: From my tests:

<input type="url" value="http://example.com">

I've come up with this pattern:

<input(.*)value=["\']https?:\/\/

But I'm not sure how to implement this regex to skip over any <input> field that match this logic. I've tried the following logic, but it didn't work:

# Skip input fields with links
if ( preg_match( '|<input(.*)value=["\']https?:\/\/|', $links ) ) {
    return $links;
}
# If 'Relative' option is selected, remove domain from all internal links
if ( $this->option == 2 ) {
    $website = preg_replace( '|https?:\/\/|', '', home_url() );
    $links = preg_replace( '|https?:\/\/' . $website . '|', '', $links );
}
# For all external links, remove protocols
$links = preg_replace( '|https?:\/\/|', '//', $links );

Thanks to Wiktor Stribiżew, this is the working regex:

/<input\b[^<]*\bvalue=[\"\']https?:\/\/(*SKIP)(*F)|https?:\/\//
