php如何读取xml文件标签中嵌套标签里的值

Question

帮我解决一个问题下 
参考例子：
<frame>
       <node>
               <name>1</name>
               <name>2</name>
               <name>3</name>
       <de>
</frame>
<frame>
       <node>
               <name>4</name>
               <name>5</name>
               <name>6</name>
               <name>7</name>
       <de>
</frame>
<frame>
       <node>
               <name>8</name>
               <name>9</name>
               <name>10</name>
               <name>11</name>
       <de>
</frame>
<frame>
       <node>
               <name>1</name>
               <name>2</name>
               <name>3</name>
               <name>4</name>
               <name>5</name>
               <name>6</name>
       <de>
</frame>
<frame>
       <node>
               <name>1</name>
               <name>2</name>
               <name>3</name>
       <de>
</frame>
结果是要得到每一个<frame>中<name>值
结果类似：array（0=>{1,2,3},1=>{4,5,6,7},2=>{8,9,10,11},3=>{1,2,3,4,5,6},4=>{1,2,3}）

Answer 1

xml的对象有很多，自己google吧..
另外也可以用正则表达式来读写xml..就是麻烦点。

Answer 2

正则方法。试试。$con=file_get_contents('test.xml');
preg_match_all('/<frame>(.*)<\/frame>/isU',$con,$arr);foreach($arr[1] as $k=>$v){
      preg_match_all('#<name>(.*)</name>#isU',$v,$ar[$k]);
  $tem[]=$ar[$k][1];
}
print_r($tem);  Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        )    [1] => Array
        (
            [0] => 4
            [1] => 5
            [2] => 6
            [3] => 7
        )    [2] => Array
        (
            [0] => 8
            [1] => 9
            [2] => 10
            [3] => 11
        )    [3] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 4
            [4] => 5
            [5] => 6
        )    [4] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        ))
