Answer 1

您要搜索的是什么？

$xml = new SimpleXMLElement('<item id="1234">
<property name="country_id">
    <value>4402</value>
</property>
<property name="rc_maintenance_other">
</property>
<property name="claim_right_shareholder">
</property>
<property name="charges_other">
</property>
<property name="other_expenses_heating">
</property>
<property name="unpaid_bills_amount">
</property>
<property name="iv_person_phone">
    <value>03-6756711</value>
</property>
</item>
 ');

foreach ($xml->xpath('//item[@id="1234"]') as $item)
{    
    foreach ($item->children() as $child) {
      echo $child['name'] ."\n";
    }
}

您可以使用$item->categories->category循环foreach：

$source = <<<DATA
<xml>
<title>Test 123</title>
<categories>
<category>Test1</category>
<category>Test2</category>
</categories>
</xml>
DATA;

$item = simplexml_load_string($source);

foreach ($item->categories->category as $elm) {
    echo $elm . PHP_EOL;
}

这将为您提供：

Test1
Test2
