PHPのDomDocumentでXML生成

 

$dom = new DomDocument('1.0', 'utf-8');
$hoge = $dom->appendChild($dom->createElement('Hoge'));
echo $dom->saveXML();

で

<?xml version="1.0" encoding="utf-8"?>
<Hoge/>

$dom = new DomDocument('1.0', 'utf-8');
$hoge = $dom->appendChild($dom->createElement('Hoge'));
$hogeAttr = $hoge->appendChild($dom->createAttribute('Name'));
echo $dom->saveXML();

で

<?xml version="1.0" encoding="utf-8"?>
<Hoge Name=""/>

$dom = new DomDocument('1.0', 'utf-8');
$hoge = $dom->appendChild($dom->createElement('Hoge'));
$hogeAttr = $hoge->appendChild($dom->createAttribute('Name'));
$hogeAttr->value = "Fuga";
echo $dom->saveXML();

で

<?xml version="1.0" encoding="utf-8"?>
<Hoge Name="Fuga"/>

$dom = new DomDocument('1.0', 'utf-8');
$hoge = $dom->appendChild($dom->createElement('Hoge'));
$hogeAttr = $hoge->appendChild($dom->createAttribute('Name'));
$hogeAttr->value = "Fuga";
$moge = $hoge->appendChild($dom->createElement('Moge'));
echo $dom->saveXML();

で

<?xml version="1.0" encoding="utf-8"?>
<Hoge Name="Fuga">
　<Moge/>
</Hoge>

$dom = new DomDocument('1.0', 'utf-8');
$hoge = $dom->appendChild($dom->createElement('Hoge'));
$hogeAttr = $hoge->appendChild($dom->createAttribute('Name'));
$hogeAttr->value = "Fuga";
$moge = $hoge->appendChild($dom->createElement('Moge', 'Moga'));
echo $dom->saveXML();

で

<Hoge Name="Fuga">
　<Moge>Moga</Moge>
</Hoge>

となる感じ。ノードひとつ追加するにもなんか見づらい感じになるので
僕は適当なfunction作って自分が見やすいようにやってますYO。
