1、访问具有相同元素名称的节点

2、通过foreach循环所有相同元素名称的子节点

以下为引用的内容:

foreach($xml->channel->item as $key=>$value){

print “Title: ” . $item->title . “\n”;

}

3、输出整个文档

echo $xml->asXML();

4、把节点作为字符串输出

echo $xml->channel->item[0]->asXML();

这将输出文本

以下为引用的内容:

//menu.example./dishes.php?dish=cuke

Gentle flavors of the sea that nourish and refresh you.

带文件名参数的asXML将会把原本输出的内容保存为一个文件

$xml->channel->item[0]->asXML(“item[0].xml”);

完整的代码:

以下为引用的内容:

rss.xml

menu.example./

These are your choices of what to eat tonight.

menu.example./dishes.php?dish=cuke

Gentle flavors of the sea that nourish and refresh you.

menu.example./dishes.php?dish=giblets

Rich giblet flavor infused with salt and spice.

menu.example./dishes.php?dish=abalone

There's no mistaking the special pleasure of abalone.

rss.php文件内容如下:

$xml = simplexml_load_file(“rss.xml”);

echo “

”.$xml->channel->title.“

”;

echo “

”;

echo “

• Title:”.$xml->channel->item[0]->title.“
”;

echo “

• Title:”.$xml->channel->item[1]->title.“
”;

echo “

• Title:”.$xml->channel->item[2]->title.“
”;

echo “

”;

print “Title: ” . $xml->channel->item[0]->title . “\n
”;

print “Title: ” . $xml->channel->item[1]->title . “\n
”;

print “Title: ” . $xml->channel->item[2]->title . “\n
”;

echo “

---

”;

foreach ($xml->channel->item[0] as $element_name => $content) {

print “The $element_name is $content\n
”;

}

echo “

---

”;

print_r($xml);

echo $xml->channel->item[0]->asXML();

?>

任何XML文本在输出前最好用 htmlentiteis() 函数编码后再输出,否这可能出现问题
