[英]I am not getting attribute name from xml response in php?
我从API获得XML响应,但遇到了一个小问题。 我无法从XML响应中获取属性name
。
这是我尝试获取name
属性的代码,但无法获取,请帮助我。
$xml = new SimpleXMLElement($response);
echo "<pre>"; print_r($xml);die();
当我执行我上面的代码不显示name
属性,如order_id, origin,destination
。它显示,而0,1,2键不是显示name
属性。

如果您阅读有关SimpleXML的文章,那么您会发现执行print_r
并不能提供所有数据。 如果您想要field
元素的name
属性,则可以执行以下操作:
$xml = new SimpleXMLElement($response);
foreach ( $xml->object[0]->field as $field ) {
echo $field['name'].PHP_EOL;
}
foreach
将获取已加载的XML,然后选择第一个object
元素([0]将选择第一个object
元素),并在其中每个field
元素。 echo
行使用数组表示法来获取name
属性。
如果需要特定的object
元素,则可以使用XPath查找该对象,并执行与上面类似的操作,然后将每个对象打印出来。
$objectRec = $xml->xpath('//object[@pk="2"]')[0];
foreach ( $objectRec->field as $field ) {
echo $field['name'].PHP_EOL;
}
上面的XPath选择<object pk="2"...>
元素。 请注意, ->xpath()
返回匹配节点的数组,因此在这里我仅使用第一个([0])。
为了帮助检查选定的元素,并且在print_r
帮助不大的情况下,可以使用asXML()
输出节点的XML。
$objectRec = $xml->xpath('//object[@pk="1"]')[0];
echo $objectRec->asXML();
