php DOMDocument application example (XML creation, addition, deletion, modification)

$xmlpatch = 'index.xml';
$_id = '1';
$_title = 'title1';
$_content = 'content1';
$_author = 'author1' ;
$_sendtime = 'time1';
$_htmlpatch = '1.html';
$doc = new DOMDocument('1.0', 'utf-8');
$doc -> formatOutput = true;
$root = $doc -> createElement_x('root');//New node
$index = $doc -> createElement_x('index');//New node
$url = $doc -> createAttribute('url ');//New attribute
$patch = $doc -> createTextNode($_htmlpatch);//New TEXT value
$url -> appendChild($patch);//Set $patch text to $url attribute The value of
$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);//Node value
$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);//Set $id as the attribute of the index node, the following is similar to
$index -> appendChild($title);
$index -> appendChild($content);
$index -> appendChild($url);
$index -> appendChild($author);
$index -> appendChild($sendtime);
$root -> appendChild($index);//Set index to root byte Click
$doc -> appendChild($root);//Set root as the follow node
$doc -> save($xmlpatch);//Save the file
echo $xmlpatch . ' has create success';

XML operation

 2. add.php adds functions (similar to the index.php file, mainly adding a load and $root = $doc -> documentElement gets the node
 $xmlpatch = 'index.xml';
$_id = '2';
$_title = 'title2';
$_content = 'content2';
$_author = 'author2';
$_sendtime = 'time2';
 $_htmlpatch = '2.html';
$doc = new DOMDocument();
$doc -> formatOutput = true;
if($doc -> load($xmlpatch)) {
$root = $doc - > documentElement;//Get the root node (root)
$index = $doc -> createElement_x('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 {
