我正嘗試讀取在元素名稱中具有' - '的xml源。飼料可以在這裏找到。在某些元素名稱中使用' - '讀取XML Feed
http://forecast.weather.gov/MapClick.php?lat=42.19774&lon=-121.81797&FcstType=dwml
我是新來的PHP,所以我可能俯瞰一些基本的東西。我正在使用SimpleXML來閱讀提要。這裏是我用來找出我的問題的一些基本代碼。我讀了wordedForecast和min temp,沒有任何問題。當我嘗試閱讀的條件圖標的PHP不工作(這是我在底部註釋掉的部分),我相信這個問題的答案很簡單
<?php
$feed_url = 'http://forecast.weather.gov/MapClick.php?lat=42.19774&lon=-121.81797&FcstType=dwml';
$ch = curl_init($feed_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
if (!empty($result))
{
$xml = new SimpleXMLElement($result);
print "<br> Discription\n";
$wordedForecast = $xml->data->parameters->wordedForecast->text;
foreach ($wordedForecast as $value)
{
print "<br> $value\n";
}
print "<br> Min Tempature\n";
$Tempature = $xml->data->parameters->temperature->value;
foreach ($Tempature as $value)
{
print "<br> $value\n";
}
print"<br>conditions Icon link\n";
//This is one of the elements that I am stumped on how to read.
/* $conditions= $xml->data->parameters->conditions-icon->icon-link;
foreach ($conditions as $value)
{
print "<br> $value\n";
}
*/
}
?>
,但我已用完關於如何去做的想法。我有與<time-layout>
,<probability-of-precipitation>
和<weather-conditions>
元素相同的問題。
感謝您的任何答案或想法如何讓它工作。
