PHP在foreach循环中迭代simplexml [英] PHP Iterating simplexml in foreach loop

问题描述

我有一个simplexml对象，如下所示：

 <？xml version =1.0？> 
< SalesInvoices xmlns：xsd =http://www.w3.org/2001/XMLSchemaxmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns = http://api.unleashedsoftware.com/version/1\"> 
< SalesInvoice> 
< OrderNumber> 100< / OrderNumber> 
< / SalesInvoice> 
< SalesInvoice> 
< OrderNumber> 101< / OrderNumber> 
< / SalesInvoice> 
< / SalesInvoices> 
  

我想遍历它，只打印订单号。我使用这个脚本：

$ $ p $ $ $ $ $ $ $ $ foreach $ $回声你好;
echo $ salesinvoice-> OrderNumber;





$ b当我这样做的时候， 你好不打印。我做错了什么？

解决方案

<？php

$ string ='<？xml version =1.0？>
< SalesInvoices xmlns：xsd =http://www.w3.org/2001/XMLSchemaxmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns = 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;
}


I have a simplexml object which looks as below

<?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>

I want to iterate through it and print only the order number. I use this script:

foreach ($xml->SalesInvoices->SalesInvoice as $salesinvoice) {
    echo "hello";
    echo $salesinvoice->OrderNumber;
}

When I do this I get no output from the loop at all, even the "hello" does not print. What am I doing wrong?

解决方案

Do

<?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;
}
