This article describes the php parsing xml method in detail in the form of examples. Share it with everyone for your reference. The specific analysis is as follows:

The books.xml file is as follows:

//创建一个DOMDocument对象

$doc=new DOMDocument();

//加载XML文件

$doc->load("books.xml");

//获取所有的book标签

$bookDom=$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;

1. DOM parsing XML 　?

<🎜>//Create a DOMDocument object<🎜> <🎜>$doc=new DOMDocument();<🎜> <🎜>//Load XML file<🎜> <🎜>$doc->load("books.xml"); //Get all book tags $bookDom=$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."
"; echo "author：".$author."

"; echo "price：".$price ."
"; echo "**********************************
"; } ?>

　2. xml_parse_into_struct

Create a parser, parse xml data into an array, release the parser, and then extract the desired value from the array.

// 读取xml文件

$file = "books.xml";

$data = file_get_contents($file);

// 创建解析器

$parser = xml_parser_create();

// 将 XML 数据解析到数组中

xml_parse_into_struct($parser, $data, $vals, $index);

// 释放解析器

xml_parser_free($parser);

// 数组处理

$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 "

";</p>
            <p>print_r($arr);</p>
            <p>echo "

$file="books.xml";

$xml = simplexml_load_file($file);

echo "

";</p>
            <p>print_r($xml);</p>
            <p>echo "
