共分四个文件,分别是创建、增加、删除、修改四个功能,变量都是写死的,改一改用$_POST方式接收就可以用了
//index.php 创建功能formatOutput = true; jb51.net$root = $doc -> createElement('root');//新建节点 jb51.net$index = $doc -> createElement('index');//新建节点 jb51.net$url = $doc -> createAttribute('url');//新建属性 $patch = $doc -> createTextNode($_htmlpatch);//新建TEXT值 $url -> appendChild($patch);//将$patch文本设为$url属性的值 jb51.net$id = $doc -> createAttribute('id'); $newsid = $doc -> createTextNode($_id); $id -> appendChild($newsid); jb51.net$title = $doc -> createAttribute('title'); $newstitle = $doc -> createTextNode($_title); $title -> appendChild($newstitle); jb51.net$content = $doc -> createTextNode($_content);//节点值 jb51.net$author = $doc -> createAttribute('author'); $newsauthor = $doc -> createTextNode($_author); $author -> appendChild($newsauthor); jb51.net$sendtime = $doc -> createAttribute('time'); $newssendtime = $doc -> createTextNode($_sendtime); $sendtime -> appendChild($newssendtime); jb51.net$index -> appendChild($id);//将$id设为index节点的属性,以下类同 $index -> appendChild($title); $index -> appendChild($content); $index -> appendChild($url); $index -> appendChild($author); $index -> appendChild($sendtime); jb51.net$root -> appendChild($index);//设置index为root字节点 jb51.net$doc -> appendChild($root);//设置root为跟节点 jb51.net$doc -> save($xmlpatch);//保存文件 jb51.netecho $xmlpatch . ' has create success'; jb51.net?> jb51.netXML操作 jb51.net
//add.php 增加功能(跟index.php文件差不多,主要就是加个load载入跟 $root = $doc -> documentElement获得跟节点
formatOutput = true; if($doc -> load($xmlpatch)) { $root = $doc -> documentElement;//获得根节点(root) $index = $doc -> createElement('index'); jb51.net$url = $doc -> createAttribute('url'); $patch = $doc -> createTextNode($_htmlpatch); $url -> appendChild($patch); jb51.net$id = $doc -> createAttribute('id'); $newsid = $doc -> createTextNode($_id); $id -> appendChild($newsid); jb51.net$title = $doc -> createAttribute('title'); $newstitle = $doc -> createTextNode($_title); $title -> appendChild($newstitle); jb51.net$content = $doc -> createTextNode($_content); jb51.net$author = $doc -> createAttribute('author'); $newsauthor = $doc -> createTextNode($_author); $author -> appendChild($newsauthor); jb51.net$sendtime = $doc -> createAttribute('time'); $newssendtime = $doc -> createTextNode($_sendtime); $sendtime -> appendChild($newssendtime); jb51.net$index -> appendChild($id); $index -> appendChild($title); $index -> appendChild($content); $index -> appendChild($url); $index -> appendChild($author); $index -> appendChild($sendtime); jb51.net$root -> appendChild($index); jb51.net$doc -> save($xmlpatch); jb51.netecho $_id . ' has been added in ' . $xmlpatch; jb51.net} else { echo 'xml file loaded error!'; } ?>XML操作-添加 jb51.net
//edit.php 修改功能(这里只修改title属性值 跟节点值)
formatOutput = true; jb51.netif($doc -> load($xmlpatch)) { $root = $doc -> documentElement; $elm = $root -> getElementsByTagName('index'); $checkexist = 0; foreach ($elm as $new) { if($new -> getAttribute('id') == $_id) { $new -> setAttribute('title', $_title); $new -> nodeValue = $_content;//修改节点值,真是太意外了,没想到跟JS一样直接能赋值... //$new -> removeChild($new -> nodevalue); $checkexist = 1; } } if($checkexist == 0) { echo $_id . ' is not found in ' . $xmlpatch; } else { $doc -> save($xmlpatch); echo $_id . ' has been changed'; } } else { echo 'xml file loaded error!'; } jb51.net?>XML操作-修改 jb51.net
//del.php 删除功能
formatOutput = true; if($doc -> load($xmlpatch)) { $root = $doc -> documentElement; $elm = $root -> getElementsByTagName('index'); foreach ($elm as $new) { if($new -> getAttribute('id') == $_id) { if($root -> removeChild($new)) { echo $_id . ' has been deleted'; } else { echo $_id . ' delete failed'; } } } $doc -> save($xmlpatch); } else { echo 'xml file loaded error!'; } jb51.net?>XML操作-删除 jb51.net
总结一下,创建跟添加主要用的就是create跟appendChild,create后边跟Element就是创建节点,跟Attribute就是创建属性,TextNode就是创建值,然后appendChild就是设置从属关系,这么一看非常简单。删除与修改都是用先获得节点列表getElementsByTagName然后foreach遍历想要修改的节点.
