XMl 各地區(qū)天氣情況的詳細(xì)信息，并將解析的數(shù)據(jù)入庫(kù)

1、關(guān)于DOM

文件名：city.php

2、XML基于事件,循環(huán)出各地區(qū)天氣信息：jiexi.php

<?php
header("content-type:text/html;charset=utf-8");
$file = 'http://flash.weather.com.cn/wmaps/xml/china.xml';
$stack = array();
 
function startTag($parser, $name, $attrs) 
{
    global $stack;
    $tag=array("name"=>$name,"attrs"=>$attrs);   
    array_push($stack,$tag);
}
 
function cdata($parser, $cdata)
 {
     global $stack,$i;
     if(trim($cdata))
     {     
        $stack[count($stack)-1]['cdata']=$cdata;    
     }
 }
 
function endTag($parser, $name) 
{
    global $stack;   
   $stack[count($stack)-2]['children'][] = $stack[count($stack)-1];
    array_pop($stack);
}
 
$xml_parser = xml_parser_create();
 xml_set_element_handler($xml_parser, "startTag", "endTag");
 xml_set_character_data_handler($xml_parser, "cdata");
 
$data = xml_parse($xml_parser,file_get_contents($file));
 if(!$data) {
    die(sprintf("XML error: %s at line %d",
 xml_error_string(xml_get_error_code($xml_parser)),
 xml_get_current_line_number($xml_parser)));
 }
 
xml_parser_free($xml_parser);
 
print("<pre>\n");
 print_r($stack);
 print("</pre>\n");
