XML namespace

Post by strohmy » 01 Sep 2013, 09:55

Hey everybody,

I try to read out some parameters from this xml file. There is a namespace for the yweather defined. what is the detailed syntax for this namespace. What do i have to write into NS1 and what do I have to write in the XPath expression to get the yweather:forecast values.

Code: Select all

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

<rss xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0" xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#" version="2.0" xmlns:geo="http://generated.ns/geo">
