php修改xml的方法:首先創(chuàng)建一個(gè)代碼示例文件;然后通過(guò)“$new->nodeValue=$_content;”方法修改節(jié)點(diǎn)值即可。
php創(chuàng)建、增加、刪除、修改xml
創(chuàng)建xml 方法:
formatOutput = true;
$root = $doc -> createElement('root');//新建節(jié)點(diǎn)
$index = $doc -> createElement('index');//新建節(jié)點(diǎn)
$url = $doc -> createAttribute('url');//新建屬性
$patch = $doc -> createTextNode($_htmlpatch);//新建TEXT值
$url -> appendChild($patch);//將$patch文本設(shè)為$url屬性的值
$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);//節(jié)點(diǎn)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);//將$id設(shè)為index節(jié)點(diǎn)的屬性,以下類(lèi)同
$index -> appendChild($title);
$index -> appendChild($content);
$index -> appendChild($url);
$index -> appendChild($author);
$index -> appendChild($sendtime);
$root -> appendChild($index);//設(shè)置index為root字節(jié)點(diǎn)
$doc -> appendChild($root);//設(shè)置root為跟節(jié)點(diǎn)
$doc -> save($xmlpatch);//保存文件
echo $xmlpatch . ' has create success';
?>增加xml 的節(jié)點(diǎn)
formatOutput = true;
if($doc -> load($xmlpatch)) {
$root = $doc -> documentElement;//獲得根節(jié)點(diǎn)(root)
$index = $doc -> createElement('index');
$url = $doc -> createAttribute('url');
$patch = $doc -> createTextNode($_htmlpatch);
$url -> appendChild($patch);

} else {
echo 'xml file loaded error!';
}
?>刪除xml 的節(jié)點(diǎn)
formatOutput = true;
if($doc -> load($xmlpatch)) {
$root = $doc -> documentElement;
$elm = $root -> getElementsByTagName('index');
foreach ($elm as $new) {
if($new -> getAttribute('id') == $_id) {

} else {
echo $_id . ' delete failed';
}
}
}
