The code is as follows

Copy code

//Return all content in object form

代码如下

复制代码

//以对象形式返回所有内容  $lib = simplexml_load_file("cet4.xml");  //以数组形式返回获取的item节点         $items=$lib->item;         $wordsLength = sqlserver/42852.htm target=_blank >count($items);         //获取所有节点的下的节点值  for($i=0;$i<$wordsLength;$i++){ $word=$items[$i]; echo $word->word.'-----'.$word->trans.'-----'.$word->phonetic.' ';  }  //simplexml结合xpath无所不能  $words = $lib->xpath("//word");  //获取属性的方法  echo $words[0]['add'].' ';  echo $items[0]['pp']; ?>

$lib = simplexml_load_file("cet4.xml");

//Return the obtained item node in the form of an array

          $items=$lib->item;

          $wordsLength = sqlserver/42852.htm target=_blank >count($items);

//Get the node values ​​under all nodes

for($i=0;$i<$wordsLength;$i++){
$word=$items[$i];
echo $word->word.'-----'.$word->trans.'-----'.$word->phonetic.'
';
}
//simplexml combined with xpath is omnipotent
$words = $lib->xpath("//word");
//Method to get attributes
echo $words[0]['add'].'
';
echo $items[0]['pp'];
?>
