[英]PHP Iterating simplexml in foreach loop
我有一個simplexml對象,如下所示
<?xml version="1.0"?>
<SalesInvoices xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://api.unleashedsoftware.com/version/1">
<SalesInvoice>
<OrderNumber>100</OrderNumber>
</SalesInvoice>
<SalesInvoice>
<OrderNumber>101</OrderNumber>
</SalesInvoice>
</SalesInvoices>
我想遍歷它並僅打印訂單號。 我使用以下腳本:
foreach ($xml->SalesInvoices->SalesInvoice as $salesinvoice) {
echo "hello";
echo $salesinvoice->OrderNumber;
}
當我這樣做時,我根本沒有從循環中獲得任何輸出,即使“ hello”也不會打印。 我究竟做錯了什么?
做
<?php
$string = '<?xml version="1.0"?>
<SalesInvoices xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://api.unleashedsoftware.com/version/1">
<SalesInvoice>
<OrderNumber>100</OrderNumber>
</SalesInvoice>
<SalesInvoice>
<OrderNumber>101</OrderNumber>
</SalesInvoice>
</SalesInvoices>';
$xml = simplexml_load_string($string);
foreach($xml as $SalesInvoice) {
print $SalesInvoice->OrderNumber;
}
