php删除xml节点的方法:首先遍历所有bird节点以及每一个bird节点的所有属性;然后修改节点值;最后通过“removeChild”方法删除节点即可。
php xml读取、编辑、删除节点
代码如下:
$doc = new DOMDocument(); $doc->load('bird_base.xml'); $root = $doc->getElementsByTagName('birdList'); $root = $root->item(0); $bird = $root->getElementsByTagName('bird'); //遍历所有 bird 节点 foreach ($bird as $rootdata) { //遍历每一个 bird 节点所有属性 $speciesID= $rootdata->getElementsByTagName('speciesID')->item(0)->nodeValue; $localName= $rootdata->getElementsByTagName('localName')->item(0)->nodeValue; $engName= $rootdata->getElementsByTagName('engName')->item(0)->nodeValue; $latinName= $rootdata->getElementsByTagName('latinName')->item(0)->nodeValue; $bird = $this->bird->get_bird_detail($speciesID); if(!empty($bird)) { //修改节点值 $rootdata->getElementsByTagName('localName')->item(0)->nodeValue = $bird['localName']; $rootdata->getElementsByTagName('engName')->item(0)->nodeValue = $bird['engName']; $rootdata->getElementsByTagName('latinName')->item(0)->nodeValue = $bird['latinName']; }else { //删除节点 $rootdata->parentNode->removeChild($rootdata); } } $doc->save('bird_base.xml'); bird_base.xml 示例 <?xml version="1.0" encoding="UTF-8"?> <birdList> <bird> <speciesID>1</speciesID> <localName>雪鹑</localName> <engName>Snow Partridge</engName> <latinName>Lerwa lerwa</latinName> </bird> <bird> <speciesID>2</speciesID> <localName>藏雪鸡</localName> <engName>Tibetan Snowcock</engName> <latinName>Tetraogallus tibetanus</latinName> </bird> </birdList>
