// 使用PHP DOM-XML创建和解析XML文件
//创建XML文档对象;以后的处理过程将在此基础上进行
$doc = new_xmldoc("1.0" );
//创建根节点,并设置一个属性
$root = $doc->add_root("faq" );
$root->setattr("page", "32" );
//子节点
$one = $root->new_child("question", "");
//为子节点设置属性
$one->setattr("number", "1");
//question也创建子节点,并且给它赋值
$one->new_child("text", "1. Where to get libxml-2.0.0?");
$one->new_child("answer", "You can download the latest
release of libxml either as a source archive or
RPM package from http://www.xmlsoft.org.
The current version is libxml2-2.2.1." );
$two = $root->new_child("question", "" );
$two->setattr("number", "2");
$two->new_child("text", "2. How to configure PHP4?" );
// 创建一个不直接赋值的节点
$twoone = $two->new_child("answer", "");
// 然后给它单独赋值
$twoone->set_content("DIR is the libxml install directory
(if you just use --with-dom it defaults
to /usr), I needed to use --with-dom=/usr/local" );
$three = $root->new_child("question", "" );
$three->setattr("number", "7" );
$three->new_child("text", "7. How to use DOM XML function ?" );
$three->new_child("answer", "Read this document source for
a simple example." );
//输出到Browser
print("
".htmlspecialchars($doc->dumpmem() )."
" );
// write to file
//写回到文件
$fp = fopen("test_dom.xml", "w+" );
fwrite($fp, $doc->dumpmem(), strlen($doc->dumpmem() ));
fclose($fp);
