Creating simple xml file using Drupal

Here is the snippet to create an xml file using our custom module. We can customise tags, attributes and values for the xml elements.

    $dom = new DomDocument('1.0');

    //add root - <parent>
    $parent = $dom->appendChild($dom->createElement('parent'));

    //set attributes to <parent> tag
    $parent->setAttribute("name", "parent1");

    //add <child1> element to <parent>
    $child1 = $parent->appendChild($dom->createElement('child1'));

    //add elements to <child1>
    $schema = $child1->appendChild($dom->createElement('schema'));
    $schema->appendChild($dom->createTextNode('Schema Name')); //add <title> text node element to <schema>
    $schemaversion = $child1->appendChild($dom->createElement('schemaversion'));

    //add <child2> element to <parent>              
    $child2 = $parent->appendChild($dom->createElement('child2'));
    //add elements to <child2>
    $listr = array('value1','value2');

    $i = 1;
    foreach ($listr as $parent => $href) {
                $baby = $child2->appendChild($dom->createElement('baby'));
                $baby->setAttribute("href", $href);
                $baby->setAttribute("type", "webcontent");
                $baby->setAttribute("intendeduse", "unspecified");
                $babyfile = $baby->appendChild($dom->createElement('file'));
                $babyfile->setAttribute("href", $href);

    // generate xml
    $dom->formatOutput = true; // set the formatOutput attribute of dom Document to true
    $test1 = $dom->saveXML(); // save XML as string or file
    $dom->save('simple.xml'); // save as file
