本文章来给大家介绍一个PHP 操作xml编程之xml的crud操作,有需要了解的同学可参考.
html代码页面,代码如下:
<html> <head> <meta http-equiv="Content-type" content="text/html;charset=utf-8"> </head> <body> <form action="wordProcess.php" method="post"> <input type="text" name="enword"> <input type="hidden" name="type" value="query"> <input type="submit" value="查询"> </form> <span>添加单词</span> <form action="wordProcess.php" method="post"> 英文:<input type="text" name="enword"><br> 中文:<input type="text" name="zhword"><br> <!--<input type="hidden" name="type" value="insert"> <input type="hidden" name="type" value="update"> --> <input type="submit" name="type" value="添加"> <input type="submit" name="type" value="修改"> </form> <form action="wordProcess.php" method="post"> <input type="text" name="word"> <input type="hidden" name="type" value="delete"> <input type="submit" value="删除"> </form> </body> </html>
wordpress.php文件,代码如下:
<?php
//接收类型 看看用户做什么(查询、添加....)
$type=$_REQUEST['type'];
//echo $type;
//exit();
//创建xml文档对象
$doc=new DOMDocument();
$doc->load("words.xml");
//进行判断
if($type=="query"){
//获取用户输入的值
$enword=$_REQUEST['enword'];
//判断是否进入查询
$isEnter=false;
//获取所有单词节点
$words=$doc->getElementsByTagName("word");
//遍历单词节点
for($i=0;$i<$words->length;$i++){
$word_node=$words->item($i);
//获取不同的语种
$en_word=getNodeVal($word_node,"en");
$zh_word=getNodeVal($word_node,"zh");
//查询

exit();
}
}
//开源代码phprm.com
//获取节点的文本值
function getNodeVal(&$MyNode,$tagName){
return $MyNode->getElementsByTagName($tagName)->item(0)->nodeValue;
}
words.xml,代码如下:
<?xml version="1.0" encoding="utf-8" <words><word><en>boy</en><zh>男孩</zh></word><word><en>girl</en><zh>女孩</zh></word><word><en>fire</en><zh>火</zh></word><word><en>word</en><zh>词库</zh></word></words>
