問(wèn)題描述
我試圖對(duì)一個(gè) XML 文件進(jìn)行排序,但沒(méi)有成功.一天半后,我需要專家的幫助.謝謝.
我的 XML 文件(示例中的縮寫(xiě)):
<截止日期><截止日期><日期>2010-06-01</日期><text>夏季到期申請(qǐng)</text></截止日期><截止日期><日期>2010-07-01</日期><text>秋季到期申請(qǐng)</text></截止日期><截止日期><日期>2010-07-31</日期><text>夏季賬單到期</text></截止日期></截止日期>
我的 PHP:
';foreach($xml as $deadline) echo <<<EOF日期:{$deadline->date}文本:{$deadline->text}EOF;echo'</pre>';//結(jié)束這項(xiàng)工作?>
有沒(méi)有人有一個(gè)簡(jiǎn)單的 PHP 解決方案來(lái)在回顯到屏幕之前按日期"對(duì) XML 文件進(jìn)行排序?
謝謝
好的,抱歉之前在房子里走來(lái)走去 - 為了清楚起見(jiàn),我添加了不同的答案,但使用了我鏈接到的排序代理技術(shù).
function xsort(&$nodes, $child_name, $order=SORT_ASC){$sort_proxy = array();foreach ($nodes as $k => $node) {$sort_proxy[$k] = (string) $node->$child_name;}array_multisort($sort_proxy, $order, $nodes);}$structure = '<?xml version="1.0" encoding="utf-8" ?><截止日期><截止日期><日期>2010-06-01</日期><text>夏季到期申請(qǐng)</text></截止日期><截止日期><日期>2010-07-01</日期><text>秋季到期申請(qǐng)</text></截止日期><截止日期><日期>2010-07-31</日期><text>夏季賬單到期</text></截止日期></deadlines>';$xml = simplexml_load_string($structure);$nodes = $xml->xpath('/deadlines/deadline');//按日期排序,降序xsort($nodes, 'date', SORT_DESC);var_dump($nodes);
I have tried to get an XML file to sort and have had no luck. After a day and a-half, I need some help from an expert. Thanks.
My XML File (shortened for the example):
<?xml version="1.0" encoding="iso-8859-1"?>
<deadlines>
<deadline>
<date>2010-06-01</date>
<text>Application for Summer Due</text>
</deadline>
<deadline>
<date>2010-07-01</date>
<text>Application for Fall Due</text>
</deadline>
<deadline>
<date>2010-07-31</date>
<text>Summer Bill Due</text>
</deadline>
</deadlines>
My PHP:
<?php
$xml = simplexml_load_file($_SERVER['DOCUMENT_ROOT'].'/feeds/deadlines.xml');
// start THIS WORKS
echo'<pre>';
foreach($xml as $deadline) echo <<<EOF
Date: {$deadline->date}
Text: {$deadline->text}
EOF;
echo'</pre>';
// end THIS WORKS
?>
Does anyone have a simple PHP solution to sort the XML file on "date" prior to the echo to screen?
Thanks
Okay, sorry for going around the houses before - I've added a different answer for clarity but using the sort proxying technique I linked to.
function xsort(&$nodes, $child_name, $order=SORT_ASC)
{
$sort_proxy = array();
foreach ($nodes as $k => $node) {
$sort_proxy[$k] = (string) $node->$child_name;
}
array_multisort($sort_proxy, $order, $nodes);
}
$structure = '<?xml version="1.0" encoding="utf-8" ?>
<deadlines>
<deadline>
<date>2010-06-01</date>
<text>Application for Summer Due</text>
</deadline>
<deadline>
<date>2010-07-01</date>
<text>Application for Fall Due</text>
</deadline>
<deadline>
<date>2010-07-31</date>
<text>Summer Bill Due</text>
</deadline>
</deadlines>';
$xml = simplexml_load_string($structure);
$nodes = $xml->xpath('/deadlines/deadline');
// Sort by date, descending
xsort($nodes, 'date', SORT_DESC);
var_dump($nodes);
