How to access XML item through XSL issue

[4bidden]

I'm working with a Yahoo weather XML feed, and I can't for the life of me figure out how to access the item I need.

Here is the XML file

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<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#">

What I need is the text and temp pulled out of the yweather:condition item above. In my XSL document I can access everything fine using <xsl:value-of select="rss/channel/item/title" /> for example, but whenever I try and reference the yweather item, I don't know how to pull the attributes from inside it. I read about using the @ sign, so <xsl:value-of select="rss/channel/item/yweather:condition/@text" /> should work, but errors the application. I think it has something to do with references the item with a title such as this, yweather:condition

Its got to be something small I'm missing. Any help???

Do you have to use this one? Why not try another like weather.com?

The "yweather" portion is not part of the element name, rather it is the namespace for that element, just as in your XSLT document "xslt" is the namespace for the XSLT elements. Try

<xsl:value-of select="condition@text" />

Also, I don't think there should be a slash between condition and @text in your code, that may be the problem.

Weather.com's feed does not contain items that have ONLY the condition and ONLY the temp. Yahoo's does if I could just figure out how to use it! Grrrr

EDIT: I found a fix from another web board. Here is what needed changed. I'm not familiar enough with this to know exactly why this was needed or what it did.

1. Change the yweather namespace declaration on your XSLT to xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0"
2. Remove the rss namespace declaration on your XSLT, it's not necessary
3. Change your parameter's XPath to: rss/channel/item/yweather:condition/@text

Hi 4bidden,


I am trying to do the same thing with teh Yahoo Weather feed but was not sure with your recommendations:

Change the yweather namespace declaration on your XSLT to xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0"
2. Remove the rss namespace declaration on your XSLT, it's not necessary
3. Change your parameter's XPath to: rss/channel/item/yweather:condition/@text

I am using php 5, and can access item fine like this


$xml = @file_get_contents("Yahoo! Weather - Allentown, PA");
$xml = new SimpleXMLElement($xml);
$a = $xml->channel->item->title;

But if I am trying to access the yweather:condition and put in
$a = $xml->channel->item->yweather:condition->text I get errors on the :

Thansk for any help!
