我有这种格式的xml是自动创建的，并且想知道如何迭代它并将数据保存到mysql中
<sales>
<site_id="000001" sale_id="80" end_date="20170826" end_time="112420" />
<site_id="000002" sale_id="81" end_date="20170828" end_time="101001" />
<site_id="000003" sale_id="82" end_date="20170828" end_time="101001" />
</sales>
我可以插入到数据库中，但是它是迭代并捕获变量，我有点困惑

这是一个无效的XML，它将是这样的：
<sales>
<sale site_id="000001" sale_id="80" end_date="20170826" end_time="112420"></sale>
<sale site_id="000002" sale_id="81" end_date="20170828" end_time="101001"></sale>
<sale site_id="000003" sale_id="82" end_date="20170828" end_time="101001"></sale>
</sales>
$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadXML($xml);
$xpath = new DOMXpath($dom);
$a = $xpath->query("//sale");
$result = array();
$i = 0;
foreach($a as $b)
{
if ($b->hasAttributes())
{
$j = 0;
$tmp = array();
foreach ($b->attributes as $attr)
{
$tmp[$attr->nodeName] = $attr->nodeValue;
$j++;
}
$result[] = $tmp;
}
$i++;
}
print_r($result);
`
输出：
Array
(
[0] => Array
(
[site_id] => 000001
[sale_id] => 80
[end_date] => 20170826
[end_time] => 112420
)
[1] => Array
(
[site_id] => 000002
[sale_id] => 81
[end_date] => 20170828
[end_time] => 101001
)
[2] => Array
