The code then creates a new dompath object and uses it to return a NodeList with matching elements. The code selects the first element from the list: $xPath = new domxpath($dom); $selectedNode = $xPath->query($path)->item(0); The last block is a loop that checks the names of each of the child nodes of the <DVD> element. The code stores each value in a different variable using the PHP shorthand property textContent to access the text inside the element: foreach ($selectedNode->childNodes as $child) { if ($child->nodeName == "title") { $title = $child->textContent; } elseif ($child->nodeName == "format") { $format = $child->textContent; } elseif ($child->nodeName == "genre") { $genre = $child->textContent; } } > The page could have located the elements using other coding approaches. Using this approach allows me to show you how to use the domxpath object and different DOM scripting methods and properties. The page displays the values in the form elements: <form id="frmEditDVD" method="POST" action="editDVDAction.php"> <input type="hidden" name="txtID" value="< php echo $id; >"/> <table> <tr> <td class="emphasis">Title:</td> <td><input name="txtTitle" type="text" size="30" maxlength="50" value="< php echo $title; >"/></td> </tr> <tr> <td class="emphasis">Format:</td> <td><input name="txtFormat" type="text" size="30" maxlength="50" value="< php echo $format; >"/></td> </tr> <tr> <td class="emphasis">Genre:</td> <td><input name="txtGenre" type="text" size="30" maxlength="50" value="< php echo $genre; >"/></td> </tr> <tr> <td class="emphasis" colspan="2"> <input type="submit" id="btnAdd" value="Update DVD"/> vb.net code 39 reader VB .
