title: Locate XML node with specific attribute and change it
body: <p>I have looked through several threads here on how to locate an XML node and change an attribute. However, I cannot find a solution to my problem:</p>
  
  <p>I have an XML node which has several nodes under it with the same name (but different attributes). For example:</p>
  
  <pre><code>&lt;Configuration&gt;
    &lt;ConfigOptions&gt;
      &lt;add key="Localize" value="Off" /&gt;
      &lt;add key="Cache" value="Database" /&gt;
      &lt;add key= etc........
  </code></pre>
  
  <p>I need to use a simple VBScript to locate the <code>&lt;add&gt;</code> node where <code>key="Cache"</code> and then change the value to something else.</p>
