Time for action – getting XML data

First let's create an example of getting data from an XML file and updating the weather widget from its data. We will create a new web page called weather.html and put the markup for the weather widget into it. This page will have a Check Weather button. When clicked, it will call the weather widget's update() method. You can find the code for this example in Chapter 8/example8.1.

Next we need to create an XML file with some weather information in it. We will name the file weather.xml and place it in the data folder:

<weather>
    <location>Your City</location>
    <current_observation>
        <weather>Snow</weather>
        <temperature_string>38.3 F (3.5 C)</temperature_string>
        <feelslike_string>38 F (3 C)</feelslike_string>
        <relative_humidity>76%</relative_humidity>
        <wind_string>From the WSW at 1.0 MPH</wind_string>
