การเขียน PHP ดึงข้อมูลจาก XML มาแสดงแบบมีเงื่อนไข ตามที่เรากำหนดครับ

<? 

$dom = new DOMDocument("1.0","UTF-8");
$dom1 = new DOMDocument("1.0","UTF-8");
$dom->load("http://dgcsc.org/goldprices2.xml");
$dom1->load("http://www2.bot.or.th/RSS/fxrates/fxrate-USD.xml");
$data1 = $dom->getElementsByTagName("GoldPrice");
foreach($data1 as $GoldPrice)
{
	echo $GoldPrice->attributes->item(1)->textContent." "."(Unit : ".$GoldPrice->attributes->item(0)->textContent.")"."<hr>";	
}
$data2 = $dom->getElementsByTagName("Price");
foreach($data2 as $Price)
{
	echo $Price->attributes->item(0)->textContent." "."(".$Price->attributes->item(1)->textContent.")"."<br>";	
	$data3 = $Price->getElementsByTagName("Ask");
	$data4 = $Price->getElementsByTagName("Bid");
	$bath = $dom1->getElementsByTagName("value");
	foreach($data3 as $Ask)
	{
		foreach($bath as $th)
		{
			$THB = $th->textContent."<br>";
		}
		echo "ราคาซื้อ ":.$Ask->textContent*$THB."<br>";	
	}
	foreach($data4 as $Bid)
	{
		echo "ราคาขาย :".$Bid->textContent*$THB."<br>";
	}
}
