// 使用PHP DOM-XML創(chuàng)建和解析XML文件

//創(chuàng)建XML文檔對象；以后的處理過程將在此基礎(chǔ)上進行
$doc = new_xmldoc("1.0" );

//創(chuàng)建根節(jié)點，并設(shè)置一個屬性
$root = $doc->add_root("faq" );
$root->setattr("page", "32" );

//子節(jié)點
$one = $root->new_child("question", "");
//為子節(jié)點設(shè)置屬性
$one->setattr("number", "1");
//question也創(chuàng)建子節(jié)點，并且給它賦值
$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?" );
// 創(chuàng)建一個不直接賦值的節(jié)點
$twoone = $two->new_child("answer", "");
// 然后給它單獨賦值
$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." );

//輸出到Browser
print("<pre>".htmlspecialchars($doc->dumpmem() )."</pre>" );

// write to file
//寫回到文件
$fp = fopen("test_dom.xml", "w " );
fwrite($fp, $doc->dumpmem(), strlen($doc->dumpmem() ));
fclose($fp);

// ------------------------------------------------------
//現(xiàn)在使用xpath從XML文檔中得到內(nèi)容

$doc = xmldoc(join("", file("test_dom.xml")) );
$ctx = xpath_new_context($doc );

分享：XML輕松學習手冊(1)XML快速入門
前言 XML越來越熱，關(guān)于XML的基礎(chǔ)教程網(wǎng)絡(luò)上也隨處可見。可是一大堆的概念和術(shù)語往往讓人望而生畏，很多朋友問我：XML到底有什么用，我們是否需要學習它？我想就我個人學習過程的心得和經(jīng)驗，
