直接贴代码吧！主要有两个文件，一个查询、修改单词的表单所处的页面。然后另外一个文件用于将单词保存到XML文件中，使用的类是DOMDocument类。这个类就是用于操作XML文件的。

<head><title>test for xml file</title><script type="text/javascript"><!--function cssShow(){var b=document.getElementById("sele");if(b.value==2){document.getElementById("desc").style.display="none";document.getElementById("note").style.display="none";}else {document.getElementById("desc").style.display="inline-block";document.getElementById("note").style.display="inline-block";}}--></script></head><form  action="./test.php" method="post"> word:   <input type="text" size=20 name="word"/><br/><span  id="desc">descri: <input type="text" size=20 name="descri"/></span><br/><span id="note">note:   <input  type="text" size=20 name="note"/></span><br/><select id="sele" name="select" onchange="javascript:cssShow();"><option value="1" selected="selected">insert</option><option value="2">query</option></select><br/><input type="submit" value="submit"/></form><?php header("content-type:text/html;charset=utf-8");require_once 'xml.class.php';if(isset($_POST['select'])){$word=$descri=$note="";$dom = new XMLOper();if(isset($_POST['word'])){$word=$_POST['word'];$word=strtoupper($word);}if(isset($_POST['descri'])){$descri=$_POST['descri'];}if(isset($_POST['note'])){$note=$_POST['note'];}$arr=array($descri,$word,$note);switch($_POST['select']){case 1:if(!$dom->checkWord($word)){$dom->xml_insert($arr);$dom->save();echo "successful";}else {echo "danci has exist yet!";}exit;case 2:if(!$dom->checkWord($word)) die("no word in the dbtable");   $arr=$dom->xml_query($word);   if($arr[0]==""){die("no word in xml");}   echo "result:<br/>word:$arr[0]<br/>descri:$arr[1]<br/>note:$arr[2]";}}?>

xml.class.php文件如下：

<?phpclass XMLOper {private  $dom;private  $root;public function __construct(){$this->dom =new DOMDocument("1.0","utf-8");$this->dom->formatOutput=true;}public function xml_query($word){$bool=$this->dom->load("test.xml");if(!$bool)echo "error when load the xml file<br/>";$arr=array();$temp=$this->dom->getElementById($word);$arr[0]=$temp->getElementsByTagName("NAME")->item(0)->nodeValue;$arr[1]=$temp->getElementsByTagName("DESCRI")->item(0)->nodeValue;$arr[2]=$temp->getElementsByTagName("NOTES")->item(0)->nodeValue;return $arr;}public function setTextNode($Node,$content){$Node->appendChild($this->dom->createTextNode($content));}public function xml_insert($contentArray){$arr=array("WORD","DESCRI","NAME","NOTES");$this->setRootEle("DANCI");for($j=0;$j<4;$j++){$tempArr[$j]=$this->dom->createElement($arr[$j]);}$word=$this->root->appendChild($tempArr[0]);for($j=1;$j<4;$j++){$this->setTextNode($word->appendChild($tempArr[$j]),$contentArray[$j-1]);}$word->setAttribute("id", $contentArray[1]);}public function setRootEle($name){$this->root=$this->dom->appendChild($this->dom->createElement($name));}public function checkWord($word){$str=file_get_contents("test.xml");if(preg_match("/<NAME>".$word."<\/NAME>/", $str)==1)return true;else return false;}public function save(){$this->dom->save("temp.xml");$fp=fopen("temp.xml", "r+");//不能用w+，要不然文件就会被覆盖,这种方式会覆盖之前写过的信息,而不是插入。/*下面的一句话就可以让保存的文件的编码设为UTF-8，而文件默认编码方式为ANSI。这一点可以用记事本程序查看文件的编码方式 fwrite($fp,"\xef\xbb\xbf");*/fwrite($fp, "<?xml ?>"); fgets($fp,200);//第一行字节留有200足够,使文件指针转移到下一行//fgets($fp,200);$xml="";while(!feof($fp)){$xml.=fread($fp, 1024);}$xml.="</TABLE>";fclose($fp);$str=file_get_contents("test.xml");$pattern="/<\/TABLE>/";$replacement="";$str=preg_replace($pattern,$replacement,$str);file_put_contents("test.xml",$str);$fp=fopen("test.xml", "a+");fwrite($fp,$xml);fclose($fp);}}?>
