本文介紹了PHP應(yīng)用：php解析xml方法實(shí)例詳解，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。
本文以實(shí)例形式詳細(xì)講述了php解析xml辦法.分享給大家供大家參考.具體分析如下：PHP實(shí)例
books.xml文件如下：PHP實(shí)例
<?xml version="1.0" encoding="ISO-8859-1"?> <bookstore> <book category="children"> <title lang="en">Harry Potter</title> <author>J K. Rowling</author> <year>2005</year> <price>29.99</price> </book> <book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="web" cover="paperback"> <title lang="en">Learning XML</title> <author>Erik T. Ray</author> <year>2003</year> <price>39.95</price> </book> </bookstore>
1、DOM解析XMLPHP實(shí)例
<?php
//創(chuàng)建一個(gè)DOMDocument對(duì)象
$doc=new DOMDocument();
//加載XML文件
$doc->load("books.xml");
//獲取所有的book標(biāo)簽
$bookDom=$doc->getElementsByTagName("book");
foreach($bookDom as $book){
$title = $book->getElementsByTagName("title")->item(0)->nodeValue;
$author = $book->getElementsByTagName("author")->item(0)->nodeValue;
$year = $book->getElementsByTagName("year")->item(0)->nodeValue;
$price = $book->getElementsByTagName("price")->item(0)->nodeValue;
echo "title：".$title."<br>";
echo "author：".$author."<br>";
echo "year：".$year."<br>";
echo "price：".$price ."<br>";
echo "***********************************<br>";
}
?>
2、xml_parse_into_structPHP實(shí)例
創(chuàng)建解析器,將xml數(shù)據(jù)解析到數(shù)組,釋放解析器,再有就是從數(shù)組中提取想要的值.PHP實(shí)例
<?php
// 讀取xml文件
$file = "books.xml";
$data = file_get_contents($file);
// 創(chuàng)建解析器
$parser = xml_parser_create();
// 將 XML 數(shù)據(jù)解析到數(shù)組中
xml_parse_into_struct($parser, $data, $vals, $index);
// 釋放解析器
xml_parser_free($parser);
// 數(shù)組處理
$arr = array();
$t=0;
foreach($vals as $value) {
$type = $value['type'];
$tag = $value['tag'];
$level = $value['level'];
$attributes = isset($value['attributes'])?$value['attributes']:"";
$val = isset($value['value'])?$value['value']:"";
switch ($type) {
case 'open':
if ($attributes != "" || $val != "") {
$arr[$t]['tag'] = $tag;
$arr[$t]['attributes'] = $attributes;
$arr[$t]['level'] = $level;
$t++;
}
break;
case "complete":
if ($attributes != "" || $val != "") {
$arr[$t]['tag'] = $tag;
$arr[$t]['attributes'] = $attributes;
$arr[$t]['val'] = $val;
$arr[$t]['level'] = $level;
$t++;
}
break;
}
}
echo "<pre>";
print_r($arr);
echo "</pre>";
?>
3、用 SAX 解析器讀取 XML-----XML Simple API(SAX)解析器PHP實(shí)例
<?php $file="books.xml"; $xml = simplexml_load_file($file); echo "<pre>"; print_r($xml); echo "</pre>"; ?>
