<h4>查詢英文單詞</h4>

<form action="xmlprocess.php" method="post">

請輸入英文單詞：<input type="text" name="enword" />

<input type="submit" value="查詢" name="sub" />

</form>

<h4>添加英文單詞</h4>

<form action="xmlprocess.php" method="post">

中文意思：<input type="text" name="ch_word" />

<input type="submit" value="添加" name="add">

</form>

處理文件：xmlprocess.php

復(fù)制代碼代碼如下:

<?php

//創(chuàng)建xml對象

$xmldoc = new DOMDocument();

$xmldoc->load("words.xml");

//查詢

if(!empty($_POST['sub'])){

 $en_word = $_POST['enword'];

 $word = $xmldoc->getElementsByTagName("en");

 for($i=0;$i<$word->length;$i++){

  if($en_word==$word->item($i)->nodeValue){

   $cn_word = $xmldoc->getElementsByTagName("ch")->item($i)->nodeValue;

   break;

  }else{

   $cn_word = "找不到你所輸入的單詞";

  }

 }

 echo $cn_word;

}

//增加詞條

if(!empty($_POST['add'])){

 $en_word = $_POST['en_word'];

 $ch_word = $_POST['ch_word'];

 //獲取根節(jié)點

 $words = $xmldoc->getElementsByTagName("words")->item(0);

 //增加元素，并添加內(nèi)容

 $new_word = $xmldoc->createElement("word");

 $new_word_en = $xmldoc->createElement("en");

 $new_word_en->nodeValue = $en_word;

 $new_word_ch = $xmldoc->createElement("ch");

 $new_word_ch->nodeValue = $ch_word;

 //元素之間掛載，意思是將子元素與父元素相連

 $new_word->appendChild($new_word_en);

 $new_word->appendChild($new_word_ch);

 $words->appendChild($new_word);

 //保存

 $xmldoc->save("words.xml");
