當我嘗試從我的雅虎天氣api提取描述時,我遇到了問題,我認爲問題可能是找到確切的路徑。無法從雅虎天氣api提取描述標籤
<?php
\t $url ="https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(55844479)%20where%20text%3D%22Riga%2C%20Lv%22)&format=xml&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
\t $error = "";
\t $file = fopen($url, "r");
\t
\t if($file == false)
\t {
\t \t $error = "File open error";
\t }
\t else
\t {
\t \t $stringXML = "";
\t \t while (feof($file)==false)
\t \t {
\t \t \t $stringXML.= fread($file, 8192);
\t \t }
\t \t $xml = new SimpleXMLElement($stringXML);
\t \t fclose($file);
\t \t $description = $xml->results->link->description;
\t }
?>
<html>
\t <head>
\t \t <title>Yahoo weather API</title>
\t </head>
\t <body>
\t
\t \t <h1>Yahoo weather api</h1>
<?php
\t if($error == "")
\t {
\t \t echo "<h3>Description:".$description."</h3>";
\t }
\t else
\t {
\t echo "<p>".$error."</p>";
\t }
?> \t
\t </body>
</html>
任何人的頭腦幫助我? :)
謝謝!然而,我需要第二個描述標籤,其中包含cdata :) –
它在*項目*,所以它會是$ description = $ xml-> results-> channel-> item-> description;查看編輯@RalfsR – eeetee
非常感謝,現在工作很好! –
