---------------------------------------------------------------------------------------
<your code>
----------------------------------------------------------------------------------------
 
<canvas>
  <dataset name="dset" src="queue.xml"/>
  <dataset name="basics" src="stubbed-out-until-i-know-what-to-load"/>
 
<simplelayout axis="y"/>
 
  <view datapath="dset:/queue/status/request">
     <script>
         var d = canvas.datasets.basics;
         d.setAttribute('src', 'requests/@id/basics.xml");
     </script>
 
    <simplelayout axis="x"/>
    <text datapath="@id"/>
    <text datapath="basics:/request/study"/>
    <text datapath="basics:/request/experiment"/>
    <text datapath="basics:/request/status"/>
  </view>
</canvas>
 
--------------------------------------------------------------------------------
</yourcode>

  <dataset name="basics" src="stubbed-out-until-i-know-what-to-load"/>
 
<simplelayout axis="y"/>
 
  <view datapath="dset:/queue/status/request">     
     <method event="ondata">
      var d = canvas.datasets.basics; 
      d.setAttribute('src', 'requests/'+this.datapath.getNodeAttribute('id')+'/basics.xml');
     </method>     
     
 
    <simplelayout axis="x"/>
    <text datapath="@id"/>
    <text datapath="basics:/request/study"/>
    <text datapath="basics:/request/experiment"/>

good lucky,i'm sorry for my bad english.


Newbie here. I know so little, I don't even know how to properly title
this thread.

My data is in several xml files and I want to combine them and look at a
summary table.

I want to see this:

id study experiment status
-----------------------------------------------
1053 myStudy MyExperiment pending
1054 myStudy2 MyExperiment2 pending
1 myStudy3 MyExperiment3 inprogress
...

Top level file named queue.xml .. looks like this:














And the details of each request are in different files based on their id. 
For now, let's just look at a file called basics.xml.

E.G. This lives in directory requests/1053 where 1053 is the request id.
requests/1053/basics.xml

in there, we have:



1
pending
MyExperiment
MyStudy


I want to change the src of the 'details' dataset depending on which item
in the queue I am currently looking at. My first (and feeble) attempt is
this, which doesn't work for several reasons. I apparently can't nest a
script tag like that, and the requests/@id/basics.xml doesn't do the XPath
substitution. Obviously I have no idea what I'm doing.









         var d = canvas.datasets.basics;
         d.setAttribute('src', 'requests/@id/basics.xml"/>
     









I couldn't find any examples to help me along these lines, and I just
don't have any idea about how to override methods, or plug into hooks, or
whatever it takes to get this done.

Thanks for any help.

Donald
