解析雅虎天气API返回的XML数据

解析雅虎天气API返回的XML数据

使用XMLReader解析

* $url = 'https://www.360docs.net/doc/e88578255.html,/forecastrss?w=15015432&u=c';

* $reader = new XMLReader();

* $reader->open($url,'utf-8');

* while($reader->read()){

* if($reader->name == 'yweather:condition'){

* $code = $reader->getAttribute('code'); //获取天气代码

* $temp = $reader->getAttribute('temp'); //获取温度

* }

* if($reader->name == 'yweather:atmosphere'){

** $humi = $reader->getAttribute('humidity'); //获取湿度

** }

** }

使用DOMDocument解析

** $url = 'https://www.360docs.net/doc/e88578255.html,/forecastrss?w=15015432&u=c';

** $yweather = "https://www.360docs.net/doc/e88578255.html,/ns/rss/1.0"; //命名空间

** $res = new DOMDocument();

** $res->load($url);

**

** $node = $res->getElementsByTagNameNS($yweather, 'atmosphere');

** $humi = $node->item(0)->attributes->item(0)->nodeValue; //获取湿度

** $node = $res->getElementsByTagNameNS($yweather, 'condition');

** $code = $node->item(0)->attributes->item(1)->nodeValue; //获取天气代码** $temp = $node->item(0)->attributes->item(2)->nodeValue; //获取温度

** switch($code){
