Our XML File

Here is our XML file.

We are going to insert a new <Link> child element that holds sibling elements <title> and <url>.

<?xml version="1.0" encoding="ISO-8859-1"?>
<MyLinksCentral>
    <Links>
        <Link>
            <title>Krio Media</title>
            <url>http://www.krio.me</url>
        </Link>
        <Link>
            <title>SEO Miami</title>
            <url>http://www.mercadeoporinternet.com/</url>
        </Link>
    </Links>
</MyLinksCentral>

How To Add The XML Elements

And here is how we add the new elemnts to the document

  $xdoc = new DomDocument;
  $xdoc->Load('MyLinksCentral.xml');

        $links = $xdoc->getElementsByTagName('Links')->item(0);
        $newLinkElement = $xdoc ->createElement('Link');
        $newTitleElement = $xdoc ->createElement('title');
        $newURLElement = $xdoc ->createElement('url');

        $urlNode = $xdoc ->createTextNode ('Google');
        $titleNode = $xdoc ->createTextNode ('http://www.google.com');

        $newTitleElement -> appendChild($titleNode);
        $newURLElement -> appendChild($urlNode);

        $newLinkElement -> appendChild($newTitleElement);
        $newLinkElement -> appendChild($newURLElement);

        $links -> appendChild($newLinkElement);

$xdoc->save('MyLinksCentral.xml');

Step-By-Step Analysis Of The XML

Load – We load the XML file.

getElementsByTagName – We get the Links element, which holds all of our links.

createElement – We create the elements that we will be inserting into our XML file and save them into a variable.

createTextNode – We place the values of the elements into variables. In this case it is the URL and Title we want. We we will inserting Google as the Title and http://google.com as the URL.

appendChild – We put the text we just created into the actual elements <title> and <url>.

appendChild – The next set of appendChild’s are to place the complete <title> and <url> tags inside of our <Link> element.

The final appendChild is to insert the final <Link> tag into the <Links> element of the XML file to be saved.
