我需要使用PHP删除XML文件的元素。

这是我的XML文件

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <GetVehiculesLocationResponse xmlns="http://google.fr/">
            <GetVehiculesLocationResult>
                <Location>
                    <idVH>001</idVH>
                    <date>2020-06-30T09:06:39</date>
                    <latitude>111111</latitude>
                    <longitude>11111</longitude>
                </Location>
                <Location>
                    <idVH>002</idVH>
                    <date>2020-04-02T13:45:51</date>
                    <latitude>1111111</latitude>
                    <longitude>111111</longitude>
                </Location>
                <Location>
                    <idVH>11111111</idVH>
                    <date>2020-03-24T21:49:46</date>
                    <latitude>1111111</latitude>
                    <longitude>11111111</longitude>
                </Location>
            </GetVehiculesLocationResult>
        </GetVehiculesLocationResponse>
    </soap:Body>
</soap:Envelope>

我想删除idVH等于002的元素

我使用这个代码不工作

$xml1 = simplexml_load_string($result); 
$items = $xml1->xpath("/soap:Envelope/soap:Body/GetVehiculesLocationResponse/GetVehiculesLocationResult/Location[idVH = 002]");

foreach ($items as $i) unset($i[0]);
   echo $xml1->asXML();
