01 <?php
02 $file = "books.xml";
03 $fp = fopen($file, "rb") or die("cannot open file");
04 $str = fread($fp, filesize($file));
05
06
07        
08 $xml = new DOMDocument();
09 $xml->formatOutput = true;
10 $xml->preserveWhiteSpace = false;
11 $xml->loadXML($str) or die("Error");
12
13 // original
14 echo "<xmp>OLD:\n". $xml->saveXML() ."</xmp>";
15
16 // get document element
17 $root   = $xml->documentElement;
18 $fnode  = $root->firstChild;
19
20 //add a node
21 $ori    = $fnode->childNodes->item(2);
22
23 $id     = $xml->createElement("id");
24 $idText = $xml->createTextNode("3");
25 $id->appendChild($idText);
26
27 $title     = $xml->createElement("title");
28 $titleText = $xml->createTextNode("PHP Framework");
29 $title->appendChild($titleText);
30
31 $author     = $xml->createElement("author");
32 $authorText = $xml->createTextNode("Reza Christian");
33 $author->appendChild($authorText);
34
35 $book   = $xml->createElement("book");
36 $book->appendChild($id);
37 $book->appendChild($title);
38 $book->appendChild($author);
39
40 $fnode->insertBefore($book,$ori);
41
42 echo "<xmp>NEW:\n". $xml->saveXML() ."</xmp>";
