title: Reading XML in id="key" value="value" attribute format?
body: <p>How can I read XML in the attribute format into a ExtJS Store, where key/values
  are specified on one row as id/value?  I'm more familiar with the second format
  given below.</p>
  
  <pre>
  &lt;?xml version="1.0" encoding="UTF-8"?>
  &lt;XMLResponse>
      &lt;data>
          &lt;row>
              &lt;column id="title" value="Star Wars"/>
              &lt;column id="director" value="Lucas"/>
              &lt;column id="year" value="1977"/>
          &lt;/row>
          &lt;row>
              &lt;column id="title" value="Jaws"/>
              &lt;column id="director" value="Spielberg"/>
              &lt;column id="year" value="1975"/>
          &lt;/row>
      &lt;/data>
  &lt;/XMLResponse>
  </pre>
  
  <p>The more traditional way of writing XML.</p>
  
  <pre>
  &lt;?xml version="1.0" encoding="UTF-8"?>
  &lt;XMLResponse>
      &lt;data>
          &lt;row>
              &lt;title>Star Wars&lt;/title>
              &lt;director>Lucas&lt;/director>
              &lt;year>1977&lt;/year>
          &lt;/row>
          &lt;row>
              &lt;title>Jaws&lt;/title>
              &lt;director>Spielberg&lt;/director>
              &lt;year>1975&lt;/year>
          &lt;/row>
      &lt;/data>
  &lt;/XMLResponse>
  </pre>
