问题描述
<?php
$doc = new DOMDocument();
$doc->load('http://weather.yahooapis.com/forecastrss?p=VEXX0024&u=c');
$channel = $doc->getElementsByTagName("channel");
foreach($channel as $chnl)
{
$item = $chnl->getElementsByTagName("item");
foreach($item as $itemgotten)
{
$describe = $itemgotten->getElementsByTagName("description");
$description = $describe->item(0)->nodeValue;
echo $description;
}
}
?>
您将看到一个简单的脚本，该脚本从上述url返回标签的内容.关键是我不需要那种内容，我需要标签里面的那个.我需要属性 code ， temp ，文本.我如何用我的实际代码这么简单?谢谢
And as you can see is a simple script who return the content of the tag from the above url. The thing is that i dont need that content, i need the one who is inside the tag . I need the attributes code, temp, text. How do i do that simple with my actual code? Thanks
标签内容的示例:
<yweather:condition text="Partly Cloudy" code="30" temp="30" date="Fri, 16 Jul 2010 8:30 am AST" />
推荐答案
类似的东西
echo $itemgotten->getElementsByTagNameNS(
"http://xml.weather.yahoo.com/ns/rss/1.0","condition")->item(0)->
getAttribute("temp");
关键是您必须使用getElementsByTagNameNS而不是getElementsByTagName并指定"http://xml.weather.yahoo.com/ns/rss/1.0"作为命名空间.
The key is that you have to use getElementsByTagNameNS instead of getElementsByTagName and specify "http://xml.weather.yahoo.com/ns/rss/1.0" as the namespace.
您知道yweather是http://xml.weather.yahoo.com/ns/rss/1.0的快捷方式，因为XML文件包含xmls属性:
You know yweather is a shortcut for http://xml.weather.yahoo.com/ns/rss/1.0 because the XML file includes a xmls attribute:
<rss version="2.0" xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0"
xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#">
这篇关于如何获得标签“< yweather:condition>".从Yahoo Weather RSS in PHP?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
