1.

<FONT style="COLOR: #ff0000">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：
<div class="codetitle"><a style="CURSOR: pointer" data="82152" class="copybut" id="copybut82152" onclick="doCopy('code82152')"> 代码如下:<div class="codebody" id="code82152">
<?xml version="1.0" standalone="yes"?>

Pride and Prejudice
<author gender="female">Jane Austen
Jane Austen's most popular work.

The Conformist
<author gender="male">Alberto Moravia
Alberto Moravia's classic psyhcological novel.

The Sun Also Rises
<author gender="male">Ernest Hemingway
The masterpiece that launched Hemingway's career.

php文件：
<div class="codetitle"><a style="CURSOR: pointer" data="73866" class="copybut" id="copybut73866" onclick="doCopy('code73866')"> 代码如下:<div class="codebody" id="code73866">
<?php
$xml=simplexml_load_file("book.xml");echo "

";
var_dump($xml);
?>

输出结果：
<div class="codetitle"><a style="CURSOR: pointer" data="51840" class="copybut" id="copybut51840" onclick="doCopy('code51840')"> 代码如下:<div class="codebody" id="code51840">
