我使用SimpleXML构建一个小脚本来解析一个小XML文件。我有几个使用SimpleXML的脚本，并且没有任何问题，所以我之前使用过它。所以我不确定它为什么不起作用。当我做print_r（$ xml）;测试它输出的元素，但我不能得到它来解析数据，否则。SimpleXML什么都不返回
这是我正在使用的测试XML。
这里的SimpleXML的
//Set path to data file
$data = "http://www.mesquiteweather.net/xml/mesquite.xml";
// Lets parse the XML feed
$xml = simplexml_load_file($data);
//Set initial output to false
$tData = false;
foreach($xml->entry as $entry){
$fname = $entry->fname;
$lname = $entry->lname;
$location = $entry->location;
$report = $entry->report;
$description = $entry->description;
片断如果有人需要在这里看到整个脚本是。

我不知道我失踪或俯瞰。我做了很多次。有什么建议么？
-Thanks
我们可以看到print_r的结果吗？ –
