PHP怎么读取各节点的值 由其是province的属性的值

Answer 1

if (file_exists('test.xml')) {
    $xml = simplexml_load_file('test.xml');
 
    print_r($xml);
} else {
    exit('Failed to open test.xml.');
}

Answer 2

$doc = new DOMDocument;
$doc->loadXML($xml);$xpath = new DOMXPath($doc);
$query = '//province/@*';
$entries = $xpath->query($query);

Answer 3

如果用simplexml_load_file  再用foreach遍历数组怎么做？

Answer 4

foreach遍历array你会吗?和这个一样.

Answer 5

if(file_exists('sitemaps.xml')) {
$xml = simplexml_load_file('sitemaps.xml');
//print_r($xml);
Foreach($xml as $k=>$v){
Echo $k,':';
print_r($v);
Echo '<br>';
}
}

Answer 6

为什么要遍历？ $entries就是一个数组，简单的方法都写给你了，还要去搞复杂的

Answer 7

给你个思路，首先取每个节点的值，将他们组成数组，之后循环就可以了！自己去参考怎么获取xml的节点问题！做程序关键是方法
