Question

我从API获得XML响应，如下所示：

$response = <<<XML
<response uri="/crm/private/xml/Leads/insertRecords">
<result>
  <message>Record(s) updated successfully</message>
  <recorddetail>
    <fl val="Id">1203498000000109001</fl>
    <fl val="Created Time">2014-09-24 09:19:44</fl>
    <fl val="Modified Time">2014-09-24 11:38:08</fl>
    <fl val="Created By"><!--[CDATA[Brydges]]--></fl>
    <fl val="Modified By"><!--[CDATA[Brydges]]--></fl>
  </recorddetail>
</result>
</response>
XML;

如果我想要消息，使用

这似乎很容易

$xml_response = new SimpleXMLElement($response); $message = $xml_response->result->message; echo $message;

但是，我正在尝试检索<fl val="id">行的内容，例如1203498000000109001.

我已经查看过很多关于SO的问题，并尝试了以下所有建议，但没有成功：

//using xpath with SimpleXMLElement
$xml_response =  new SimpleXMLElement($response);
$zoho_id = $xml_response->xpath('/response/result/recorddetail/fl[@val="Id"]');
echo $zoho_id;

//using xpath with simplexml_load_string
$xml_response =  new simplexml_load_string($response);
$zoho_id = $xml_response->xpath('/response/result/recorddetail/fl[@val="Id"]');
echo $zoho_id;

//using a foreach loop
$xml_response = new SimpleXMLElement($response);
foreach ($xml_response->result->recorddetail->fl as $fl) {
 if ((string) $fl['val'] == 'Id') {
    echo (string) $fl;
  }
}

// using a foreach loop and then a switch case over the val attribute value to only echo Id
foreach ($xml_response->result->recorddetail->fl as $fl) {
    switch((string) $fl['val']) { // Get attributes as element indices
    case 'Id':
        echo (string)$fl, ' is the Id';
        break;
    }
}

有关我如何检索我需要的内容的任何建议吗？

关注GHOSTS的建议：

print_r（$ doc）返回：

SimpleXMLElement Object ( 
    [@attributes] => Array ( 
        [uri] => /crm/private/xml/Leads/insertRecords 
    ) 
    [result] => SimpleXMLElement Object ( 
        [message] => Record(s) updated successfully 
        [recorddetail] => SimpleXMLElement Object ( 
            [FL] => Array ( 
                [0] => 1203498000000109001 
                [1] => 2014-09-24 09:19:44 
                [2] => 2014-09-24 13:06:37 
                [3] => SimpleXMLElement Object ( 
                    [@attributes] => Array ( 
                        [val] => Created By 
                    ) 
                ) 
                [4] => SimpleXMLElement Object ( 
                    [@attributes] => Array ( 
                        [val] => Modified By 
                    ) 
                ) 
            ) 
        ) 
    ) 
)

第一个xpath部分已经正确，xpath结果返回一个数组，所以请将其视为：

$xml_response =  new SimpleXMLElement($response);
$zoho_id = (string) $xml_response->xpath('/response/result/recorddetail/fl[@val="Id"]')[0];
                                                                                    //  ^
echo $zoho_id;
// assuming you're expecting one result

如果您有多个节点，则可以使用循环：

$zoho_id = $xml_response->xpath('/response/result/recorddetail/fl[@val="Id"]');
foreach($zoho_id as $node) {
    $id = (string) $node;
    echo $id;
}

或者：

$xml_response =  new SimpleXMLElement($response);
$recorddetail = $xml_response->xpath('/response/result/recorddetail');
foreach($recorddetail as $node) {
    $id_node_val = (string) $node->FL[0];
    echo $id_node_val;
}

基于节点属性值的Echo XML子节点值
