PHP获取并修改某些RSS标签的字符串

Question

我有一个RSS源的游戏。什么是最好的方式来提取然后修改和回显所选标签的文本只从每个项目？

因此，例如文本输出我想应该是：

Game: Rapunzel Split Up With Flynn (HTML5) 
Category: girl 
Image: http://www.website.com/thumb/201611/Rapunzel-Split-Up-With-Flynn.jpg 
Game: Barbie Clean Place (HTML5) 
Category: girl 
Image: http://www.website.com/thumb/201611/Barbie-Clean-Place.jpg 

有更多的项目但正如我刚才显示出许多的2。

有什么好的RSS或XML处理库我可以使用或一些简单的代码？

Answer 1

把你的XML和JSON做或数组这样你就可以访问它更容易

$xml = '<xmlstuff></xmlstuff'; // Be warned of ' xml could cause error 

$json = json_encode(simplexml_load_string($xml), true); 
$arrays = json_decode($json, true); 

echo "<pre>"; 
var_dump($arrays); 
echo "</pre>"; 

现在，您可以访问诸如阵列中的数据！

echo $name1 = $arrays['channel']['item'][0]['name']."<br>"; 
echo $name2 = $arrays['channel']['item'][1]['name']."<br><br>"; 

//MORE ADVANCED 

foreach ($arrays['channel']['item'] as $items){ 
    echo $items['name']."<br>"; 
}
