[英]Using PHP foreach loop to parse Simple XML result from AWS Cloudsearch API response
這是我第一次在這里提出問題,我也是PHP和簡單XML的新手,但我決心學習這一點。 我已經搜索了所有之前提出的所有相關問題,但是盡管看上去很相似,但仍無法將其應用於我的情況。 真令人沮喪:(。
我正在嘗試從Amazon Cloudsearch讀取XML格式的API響應。
這是原始的XML響應:
<results xmlns="http://cloudsearch.amazonaws.com/2011-02-01/results">
<rank>-text_relevance</rank>
<match-expr>(label '"mango"')</match-expr>
<hits found="99" start="0">
<hit id="mango1to100_csv_31">
<d name="imageurl">
http://st.mngbcn.com/rcs/pics/static/T6/fotos/S1/66650066_51.jpg
</d>
</hit>
<hit id="mango1to100_csv_10">
<d name="imageurl">
http://st.mngbcn.com/rcs/pics/static/T6/fotos/S1/63650060_34.jpg
</d>
</hit>
<hit id="mango1to100_csv_11">
<d name="imageurl">

</d>
</hit>
<hit id="mango1to100_csv_12">

<hit id="mango1to100_csv_13">

</results>
我已經使用SimpleXML來開始:

我正在嘗試根據結果中提供的URL讀取並顯示所顯示的每個項目的圖像。 我知道我應該在這里使用“ foreach”循環,但似乎無法正確執行,因此這是我做的很長的路要走:
<?php
$feed_url = 'http://www.myapicallexample.com';
$feed = simplexml_load_file($feed_url);
echo "<ul>";
echo "<li><img src='", $feed->hits[0]->hit[1]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[2]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[3]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[4]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[5]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[6]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[7]->d,"'></li>";
echo "</ul>";
?>
我已經嘗試通過查看其他問題的答案來嘗試foreach語句的各種組合,但是沒有任何效果。 我准備把我的電腦扔到窗外。 提前致謝!
附錄:這是我先前許多無腦嘗試之一的示例:)
<?php
$feed_url = 'http://www.myapicallexample.com';
$xml = simplexml_load_file($feed_url);
$imageurl = $xml->hits[0]->hit[1]->d;
foreach($imageurl as $a)
{
echo $a;
}
?>
$feed_url = 'http://www.myapicallexample.com';
$xml = simplexml_load_file($feed_url);
foreach($xml->hits->hit as $hit){
echo "url:".$hit->d;
}
