探讨如何使用SimpleXML函数来加载和解析XML文档_PHP教程

大量SmipleXML函数可用来加载和解析大量XML文档。
--------------------------------------------------------------------------------
1.simpleXML_load_file()函数来加载指定的XML文件到对象。如果加载文件时遇到问题，则返回FLASE。例：
book.xml文件：
代码如下:




Jane Austen
Jane Austen's most popular work.



Alberto Moravia
Alberto Moravia's classic psyhcological novel.



Ernest Hemingway
The masterpiece that launched Hemingway's career.



php文件：
代码如下:
$xml=simplexml_load_file("book.xml");echo "

";
var_dump($xml);
?>

输出结果：
代码如下:
object(SimpleXMLElement)#1 (1) {
["book"]=>
array(3) {
[0]=>
object(SimpleXMLElement)#2 (3) {
["title"]=>
string(19) "Pride and Prejudice"
["author"]=>
string(11) "Jane Austen"
["description"]=>
string(32) "Jane Austen's most popular work."
}
[1]=>
object(SimpleXMLElement)#3 (3) {
["title"]=>
string(14) "The Conformist"
["author"]=>
string(15) "Alberto Moravia"
["description"]=>
string(46) "Alberto Moravia's classic psyhcological novel."
}
[2]=>
object(SimpleXMLElement)#4 (3) {
["title"]=>
string(18) "The Sun Also Rises"
["author"]=>
string(16) "Ernest Hemingway"
["description"]=>
string(49) "The masterpiece that launched Hemingway's career."
}
}
}
