Answer 1

PHP5 有个DomDocument 自己翻手册. php4就有点麻烦了.

Answer 2

代码如下：
$str= "<?xml version=\"1.0\" encoding = \"GB2312\"?><root><op_code>1002 </op_code><op_name>gxvps </op_name><op_user>2000000301 </op_user><op_time>2008-27-06 07:57:50 </op_time><sp_id>2000000301 </sp_id><package_id>9511869734 </package_id><ret_code>1 </ret_code><result><RepReserved1>100 </RepReserved1><RepReserved2>200 </RepReserved2><RepReserved3>300 </RepReserved3></result></root>";
$xml = new SimpleXMLElement($str);
print_r($xml);

Answer 3

dddd.xml<?xml version="1.0" encoding="gb2312"?>
<tabled> <trd>
  <tdf>123423213</tdf>
<tdf>123423213ddddd</tdf>
 </trd>
  <trd>
  <tdf>dddd</tdf>
<tdf>42343dddd</tdf>
 </trd>
</tabled>
PHP代码：$file = "dddd.xml";
if(file_exists($file)) $xml = simplexml_load_file($file);echo $xml->trd[0]->tdf[0];输出结果
123423213
