php修改xml的方法:首先创建一个代码示例文件;然后通过“$new->nodeValue=$_content;”方法修改节点值即可。

php创建、增加、删除、修改xml

创建xml 方法:

  formatOutput = true; $root = $doc -> createElement('root');//新建节点 $index = $doc -> createElement('index');//新建节点 $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 $id = $doc -> createAttribute('id'); $newsid = $doc -> createTextNode($_id); $id -> appendChild($newsid); $title = $doc -> createAttribute('title'); $newstitle = $doc -> createTextNode($_title); $title -> appendChild($newstitle); $cOntent= $doc -> createTextNode($_content);//节点值 $author = $doc -> createAttribute('author'); $newsauthor = $doc -> createTextNode($_author); $author -> appendChild($newsauthor); $sendtime = $doc -> createAttribute('time'); $newssendtime = $doc -> createTextNode($_sendtime); $sendtime -> appendChild($newssendtime); $index -> appendChild($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); $root -> appendChild($index);//设置index为root字节点 $doc -> appendChild($root);//设置root为跟节点 $doc -> save($xmlpatch);//保存文件 echo $xmlpatch . ' has create success'; ?>

增加xml 的节点

 
  formatOutput = true; if($doc -> load($xmlpatch)) { $root = $doc -> documentElement;//获得根节点(root) $index = $doc -> createElement('index'); $url = $doc -> createAttribute('url'); $patch = $doc -> createTextNode($_htmlpatch); $url -> appendChild($patch); $id = $doc -> createAttribute('id'); $newsid = $doc -> createTextNode($_id); $id -> appendChild($newsid); $title = $doc -> createAttribute('title'); $newstitle = $doc -> createTextNode($_title); $title -> appendChild($newstitle); $cOntent= $doc -> createTextNode($_content); $author = $doc -> createAttribute('author'); $newsauthor = $doc -> createTextNode($_author); $author -> appendChild($newsauthor); $sendtime = $doc -> createAttribute('time'); $newssendtime = $doc -> createTextNode($_sendtime); $sendtime -> appendChild($newssendtime); $index -> appendChild($id); $index -> appendChild($title); $index -> appendChild($content); $index -> appendChild($url); $index -> appendChild($author); $index -> appendChild($sendtime); $root -> appendChild($index); $doc -> save($xmlpatch); echo $_id . ' has been added in ' . $xmlpatch; } else { echo 'xml file loaded error!'; } ?>

删除xml 的节点

  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!'; } ?>

修改XML的节点

 
  formatOutput = true; if($doc -> load($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!'; } ?>
