我有以下XML文件:
<SyncCustomerPartyMaster xmlns="http://schema.infor.com/InforOAGIS/2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:schemaLocation="http://schema.infor.com/InforOAGIS/2 http://schema.infor.com/2.9.1/InforOAGIS/BODs/Developer/SyncCustomerPartyMaster.xsd" releaseID="9.2" versionID="2.9.1">

<CustomerPartyMaster>
<PartyIDs>
<ID accountingEntity="200" lid="lid://infor.ln.dach_nausveln1_200" variationID="108">10100</ID>
<DisplayID>10100</DisplayID>
</PartyIDs>
</CustomerPartyMaster>
</DataArea>
</SyncCustomerPartyMaster>
我尝试通过XPath访问DisplayId:&#39; / SyncCustomerPartyMaster / DataArea / CustomerPartyMaster / PartyIDs / DisplayID&#39;
<?php
$xml = simplexml_load_file("example.xml");
$displayId = $xml->xpath('/SyncCustomerPartyMaster/DataArea/CustomerPartyMaster/PartyIDs/DisplayID');
print_r($xml);
echo '<br />';
echo '<br />';
print_r($displayId);
?>
但是print_r($ display_id)只返回一个空数组。我使用registerXPathNamespace 1摆弄了一下并没有做到这一点 - 有人能请我指出正确的方向吗?
答案 0 :(得分:3)
xmlns="http://schema.infor.com/InforOAGIS/2"
这声明了一个默认命名空间,您需要通过registerXPathNamespace()
注册,并使用注册的前缀来寻址元素。
$xml = simplexml_load_file("example.xml");
$xml->registerXPathNamespace('ns', "http://schema.infor.com/InforOAGIS/2");
$displayIds = $xml->xpath('/ns:SyncCustomerPartyMaster/ns:DataArea/ns:CustomerPartyMaster/ns:PartyIDs/ns:DisplayID');
foreach ($displayIds as $displayId) {
echo $displayId;
}
10100
