一代码
<?php class Message_XML extends DomDocument{private $Root;public function __construct() {parent:: __construct();$this->load("Rss.xml");}public function select_message($Action){$Root  = $this->documentElement;$xpath = new DOMXPath($this);$node_Record = $xpath->query("//item[title='$Action']");    for($i=0;$i<$node_Record->length;$i++){$g=0;foreach($node_Record->item($i)->childNodes as $node){ $field[$g]=iconv("UTF-8","GB2312",$node->textContent);$g++;}print "<table width='750' height='75' border='1' cellpadding='1' cellspacing='1' bordercolor='#FFFFFF' bgcolor='#0099FF'>  <tr>    <td width='126' height='25' align='center'><span class='STYLE_select5'>标题</span></td>    <td width='611'><input name='title' type='text' id='title' size='50' value='$field[0]'></td>  </tr>  <tr>    <td height='25' align='center'><span class='STYLE_select5'>链接地址</span></td>    <td><input name='link' type='text' id='link' size='60' value='$field[1]'></td>  </tr>  <tr>    <td height='25' align='center'><span class='STYLE_select5'>内容摘要</span></td>    <td><textarea name='description' cols='80' rows='5' id='description'>$field[2]</textarea></td>  </tr></table>"; }  }   }?><title>查询XML文件</title><style type='text/css'><!--.STYLE_select5 {font-size: 13px; font-weight: bold; color: #FFFFFF; }--></style><style type="text/css"><!--body,td,th {font-size: 13px;}a:link {text-decoration: none;}a:visited {text-decoration: none;}a:hover {text-decoration: none;}a:active {text-decoration: none;}.STYLE2 {font-size: 18px}--></style><body><table width=750 height=35 border=1 cellpadding=3 cellspacing=1 bordercolor="#FFFFFF" bgcolor="#0099FF">  <form name="form1" method="post" action="index.php">    <tr>      <td height=35 align="center"><span class="STYLE_select5">请输入标题名称：</span>        <input name="Action" type="text" id="Action">      &nbsp;&nbsp;<input type="submit" name="Submit" value="提交">        </td>    </tr>  </form>  <?php                                                                                                                        if($_POST[Submit]==true){ $HawkXML = new Message_XML;    $HawkXML->select_message(iconv("GB2312","UTF-8","$_POST[Action]")); }?></table></body>
