PHPによるXMLの簡単な処理

1. xml

/*
 * 手动输出xml
 * @author flyer0126
 * @since 2012/4/27
 */
header("Content-Type:text/xml");
print &#39;<?xml version="1.0"?>&#39;."\n";
print "<shows>\n";
$shows = array(
                array(
                        &#39;name&#39; => &#39;aa&#39;,
                        &#39;channel&#39; => &#39;a1&#39;,
                        &#39;start&#39; => &#39;a2&#39;
                ),
                array(
                        &#39;name&#39; => &#39;bb&#39;,
                        &#39;channel&#39; => &#39;b1&#39;,
                        &#39;start&#39; => &#39;b2&#39;
                ),
                array(
                        &#39;name&#39; => &#39;cc&#39;,
                        &#39;channel&#39; => &#39;c1&#39;,
                        &#39;start&#39; => &#39;c2&#39;
                )
);
foreach($shows as $show)
{
    print "<show>\n";
    foreach($show as $tag => $val)
    {
        print "<$tag>".htmlspecialchars($val)."</$tag>\n";
    }
    print "</show>\n";
}
print "</shows>\n";
/**
<?xml version="1.0"?>
<shows>
<show>
<name>aa</name>
<channel>a1</channel>
<start>a2</start>
</show>
<show>
<name>bb</name>
<channel>b1</channel>
<start>b2</start>
</show>
<show>
<name>cc</name>
<channel>c1</channel>
<start>c2</start>
</show>
</shows>
**/

を手動で出力する2. DOMDocument

/*
 * 通过DOMDocument生成xml
 * @author flyer0126
 * @since 2012/4/27
 */
// 创建新文档
$dom = new DOMDocument("1.0", "UTF-8");
// 创建根元素humans，并将其添加至文档
$humans = $dom->appendChild($dom->createElement("humans"));
// 创建根元素zhangying，并将其添加至humans
$zhangying = $humans->appendChild($dom->createElement("zhangying"));
// 创建name元素，并将其添加至zhangying
$name = $zhangying->appendChild($dom->createElement("name"));
$name->appendChild($dom->createTextNode("张映"));
$sex = $zhangying->appendChild($dom->createElement("sex"));
$sex->appendChild($dom->createTextNode("男"));
$old = $zhangying->appendChild($dom->createElement("old"));
$old->appendChild($dom->createTextNode("28"));
// 创建根元素tank，并将其添加至humans
$tank = $humans->appendChild($dom->createElement("tank"));
// 创建name元素，并将其添加至tank
$name = $tank->appendChild($dom->createElement("name"));
$name->appendChild($dom->createTextNode("tank"));
$sex = $tank->appendChild($dom->createElement("sex"));
$sex->appendChild($dom->createTextNode("男"));
$old = $tank->appendChild($dom->createElement("old"));
$old->appendChild($dom->createTextNode("28"));
/*// 设置author元素
$author = $book->appendChild($dom->createElement("author"));
$author->appendChild($dom->createTextNode("zhangh"));
$author->setAttribute("class", "win_close");*/
// 输出
$dom->formatOutput = true;
header('Content-Type:text/xml');
echo $dom->saveXML();
// 将文档表现形式放于book变量中
//$book = $dom->saveXML();
// 将文档输出为book.xml文件
//$dom->save("humans.xml");
/**
    <?xml version="1.0 encoding="UTF-8"?>
    <humans>
    <zhangying>
    <name>张映</name>
    <sex>男</sex>
    <old>28</old>
    </zhangying>
    <tank>
    <name>tank</name>
    <sex>男</sex>
    <old>28</old>
    </tank>
    </humans>
