Question

我想使用 php 按日期过滤我的 xml 数据

<xml>
<customer>
  <cid>1</cid>
  <amount_paid>1000</amount_paid>
  <date>2012-01-10</date>
</customer>
<customer>
  <cid>2</cid>
  <amount_paid>3000</amount_paid>
  <date>2012-01-10</date>
</customer>
<customer>
  <cid>3</cid>
  <amount_paid>1000</amount_paid>
  <date>2012-01-05</date>
</customer>
<customer>
  <cid>6</cid>
  <amount_paid>7000</amount_paid>
  <date>2012-01-21</date>
</customer>
</xml>

如何按日期过滤我的 xml？例如。我想获得 date = "2012-01-10" 的客户

看到它在行动

<?php
    $string = '<xml>
<customer>
  <cid>1</cid>
  <amount_paid>1000</amount_paid>
  <date>2012-01-10</date>
</customer>
<customer>
  <cid>2</cid>
  <amount_paid>3000</amount_paid>
  <date>2012-01-10</date>
</customer>
<customer>
  <cid>3</cid>
  <amount_paid>1000</amount_paid>
  <date>2012-01-05</date>
</customer>
<customer>
  <cid>6</cid>
  <amount_paid>7000</amount_paid>
  <date>2012-01-21</date>
</customer>
</xml>';

$xml = simplexml_load_string($string);

foreach ($xml->customer AS $customer)
{
    if ($customer->date == '2012-01-10')
    {
        echo $customer->cid . "<br>\n";
        echo $customer->amount_paid . "<br>\n";
    }
}
