我一直在尝试使用laravel解析来自USPTO分配api的响应，而一切似乎都错了。在此之前，我真的从未对xml做太多事情。
以下是xml示例：

我也尝试过使用SimpleXml，但是似乎都无法正常工作。请任何帮助将不胜感激。谢谢
答案 0 :(得分：1)
可能是由于您使用的选择器是属性，而不是实际的元素名称。这与SimpleXML等相同。但是我在这里要做的是分两个步骤进行处理。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，那么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，这仅从<result>元素中选取值）。
然后您可以使用类似的方式访问它
'publNum' => $details['publNumFirst'],
'inventionTitle' => $details['inventionTitleFirst'],
这确实假定只有一项要读取，如果还有更多项，则可能需要调整foreach()并将结果保留为数组数组（如果被卡住，请询问）。
