title: How do I update an xml file with msbuild with two namespaces?
body: <p>This msbuild below task can take into account one namespace, but in the case where I'm updating an mxml (flex) that has a mix of namespaces, can I use this task or another msbuild task to do the update?</p>
  
  <pre><code>&lt;XmlUpdate
          Prefix="fx"
          Namespace="http://ns.adobe.com/mxml/2009"
        XmlFileName="myFlexApp.mxml"
        Xpath="//mx:Application/fx:Declarations/fx:String[@id='stringId']"
        Value="xxxxx"&gt;
  </code></pre>
  
  <p>Here is the flex xml I'm trying to update:</p>
  
  <pre><code>&lt;mx:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
              xmlns:mx="library://ns.adobe.com/flex/mx" 
              xmlns:s="library://ns.adobe.com/flex/spark"&gt;
  &lt;fx:Declarations&gt;
      &lt;fx:String id="stringId"&gt;UPDATE_ME&lt;/fx:String&gt;
  &lt;/fx:Declarations&gt;&lt;/mx:Application&gt;
  </code></pre>
