Convert unordered list html markup into a multidimensional array using xpath

$total = [];
$ind = 0;
foreach ($geral as $name) {
    $s = explode("\n",$name->nodeValue);
    foreach($s as  $ss){
        if(str_contains($ss,"Status: ")){
            $total[$ind]["status"] = str_replace('Status: ','',$ss);
        }
        if(str_contains($ss,"Data  : ")){
            
            $data = str_replace('Data  : ','',$ss);
            $data = str_replace('Hora: ','',$data);
            $data = explode(" | ",$data);
            $total[$ind]["data"] = $data[0];
            $total[$ind]["hora"] = $data[1];
        }
        if(str_contains($ss,"Origem: ")){
            $total[$ind]["origem"] = str_replace('Origem: ','',$ss);
        }
        if(str_contains($ss,"Destino: ")){
            $total[$ind]["destino"] = str_replace('Destino: ','',$ss);
        }
        if(str_contains($ss,"Local: ")){
            $total[$ind]["local"] = str_replace('Local: ','',$ss);
        }
    }
    $ind++;
}

print_r($total);

Just make sure that there's a new line every after li. Inconsistencies on the HTML may ruin the output. Sorry for that.

The solution is a little easier if xpath is used twice. Once for the ul tags and once each for the underlying li tags. The splitting is done simply with explode.

$doc = new DOMDocument();
$doc->loadHTML($htmlString);
$xpath = new DOMXPath($doc);

$geral = $xpath->query('//ul[@class="linha_status"]');

$total = [];
foreach ($geral as $node) {
  $sArr = [];
  $li = $xpath->query('li',$node);
  foreach($li as $item){
    $liVal = $item->nodeValue;
    $parts = explode("|",$liVal);
    foreach($parts as $part){
      list($key,$val) = explode(':',$part);
      $sArr[trim($key)] = trim($val);
    }
  }
  $total[] = $sArr;
}

$result = json_encode($total, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);

I definitely support @jspit's recommendation of using nested xpath calls for convenience, however I prefer a few different coding choices. Here is the break down of my snippet below:

1. Load the document with UTF-8 encoding to preserve multibyte characters
2. Use xpath to iterate all <ul> tags with the qualifying class
3. Use xpath to iterate all !<li> tags nested within the qualifying <ul>
4. Split the <li> text by pipes to form 1 or more segments -- no limiter is necessary
5. Split each segment by the first occurring colon -- limiting the explosion to 2 parts is crucial because some segments contain multiple colons; removing spaces during this explosion saves having to call trim() twice later
6. Push the key-value pair in to the result array with a first level index relating to the parent ul.

Code: (Demo)

$result = [];
$doc = new DOMDocument;
$doc->loadHTML('<?xml encoding="UTF-8">' . $htmlString);
$xpath = new DOMXPath($doc);
foreach ($xpath->query('//ul[@class="linha_status"]') as $i => $ul) {
    foreach ($xpath->query('li', $ul) as $li) {
        foreach (explode("|", $li->nodeValue) as $segment) {
            [$key, $result[$i][$key]] = preg_split('/\s*:\s*/', trim($segment), 2);
        }
    }
}
var_export($result);

Output:
