如何在 laravel 5 中解析 USPTO xml 响应

Question

我一直在尝试使用 laravel 解析来自 USPTO assignments api 的响应，但一切似乎都是错误的。在此之前，我真的从来没有做过这么多的 xml。

这里是xml示例：

   <?xml version="1.0" encoding="UTF-8"?>
<response>
    <lst name="responseHeader">
        <int name="status">0</int>

这是我尝试过的：

    $client = new Client(array( 'curl' => array( CURLOPT_SSL_VERIFYPEER => false, CURLOPT_SSL_VERIFYHOST =>0), ));
    $res = $client->request('GET', 'https://assignment-api.uspto.gov/patent/basicSearch?query='.$request->input('query'));
    $respons = $res->getBody()->getContents();
    // dd($respons);
    $xml = XmlParser::extract($respons);
    $doc = $xml->parse([
        'publNum' => ['uses' => 'result.publNum'],
        'inventionTitle' => ['uses' => 'result.inventionTitle'],
        'inventors' => ['uses' => 'result.inventors'],
        'corrName' => ['uses' => 'result.corrName'],
        'corrAddress1' => ['uses' => 'result.corrAddress1'],
        'corrAddress2' => ['uses' => 'result.corrAddress2'],
        'corrAddress3' => ['uses' => 'result.corrAddress3'],
        'patAssigneeName' => ['uses' => 'result.patAssigneeName'],
        'patAssigneeAddress1' => ['uses' => 'result.patAssigneeAddress1'],
        'patAssigneeAddress2' => ['uses' => 'result.patAssigneeAddress2'],
        'patAssigneeCity' => ['uses' => 'result.patAssigneeCity'],
        'patAssigneeState' => ['uses' => 'result.patAssigneeState'],
        'patAssigneeCountryName' => ['uses' => 'result.patAssigneeCountryName'],
    ]);

    dd($doc);

我也尝试过使用 SimpleXml，但似乎一切都不起作用。请任何帮助将不胜感激。谢谢

这可能是由于您使用的选择器是一个属性而不是实际的元素名称。这与 SimpleXML 等相同，但我在这里所做的是分两步处理它。第一个使用name 属性作为键和值将其转换为关联数组。如果该值具有子元素，则这些元素本身将作为数组添加...

$xml = simplexml_load_string($respons);
$details = [];
foreach ( $xml->result->doc->children() as $element )   {
    if ( count($element) > 0 )  {
        foreach ( $element->children() as $sub )   {
            $details[(string)$element['name']][] = (string)$sub;
        }
    }
    else    {
        $details[(string)$element['name']] = (string)$element;
    }
}

print_r($details);

将给出

的输出

Array
(
    [id] => 48719-909
    [reelNo] => 48719
    [frameNo] => 909
    [conveyanceText] => ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS).
    [corrName] => LOCKE LORD LLP
    [corrAddress1] => P.O. BOX 55874
    [corrAddress2] => BOSTON, MA 02205
    [patAssignorEarliestExDate] => 2019-03-20T04:00:00Z
    [patAssignorName] => Array
        (
            [0] => CLAMEN, LIANE
            [1] => GLAZER, PAUL
        )

    [patAssigneeName] => Array
        (
            [0] => OJO, LLC
        )

    [applNum] => Array
        (
            [0] => 13096729
        )

    [intlRegNum] => Array
        (
            [0] => NULL
        )

    [applNumSize] => 1
    [patNumSize] => 1
    [inventionTitleFirst] => INJECTABLE PHYSIOLOGICALLY ADAPTIVE INTRAOCULAR LENSES (IOL'S)
    [applNumFirst] => 13096729
    [filingDateFirst] => 2011-04-28T04:00:00Z
    [intlPublDateFirst] => 0001-01-01T00:00:00Z
    [intlRegNumFirst] => NULL
    [issueDateFirst] => 0001-01-01T00:00:00Z
    [patNumFirst] => NULL
    [publDateFirst] => 2011-11-03T04:00:00Z
    [publNumFirst] => 20110270389
)

（请注意，这只会从<result> 元素中挑选出值）。

然后你可以使用类似的东西访问它

'publNum' => $details['publNumFirst'],
'inventionTitle' => $details['inventionTitleFirst'],

这确实假设只有 1 项要读取，如果还有更多，则需要调整 foreach() 并将结果保存为数组数组（询问您是否卡住了）。
