Parsing an XML file

Hi.

I have an xml file that I need to scroll down to find information under the heading Exposure. the general format is as below.

I need to pull out the "number of Images" number in a list for all the red and all the green exposures and count them.

<Exposure>
<Exposure Name=“red” NumberOfImages=“4” Read=“First”/>
<Exposure Name=“green” NumberOfImages=“4” Read=“First”/>
<Exposure Name=“red” NumberOfImages=“5” Read=“First”/>
<Exposure Name=“green” NumberOfImages=“4” Read=“First”/>

…..

<Exposure Name=“red” NumberOfImages=“6” Read=“Second”/>
<Exposure Name=“green” NumberOfImages=“7” Read=“Second”/>
<Exposure Name=“red” NumberOfImages=“8” Read=“Second”/>
<Exposure Name=“green” NumberOfImages=“9” Read=“Second”/>

so in the above, I need an two arrays, one for green and one for red such as (for red)

1 Red 4 First
1 Red 5 First
..
1 Red 6 Second
1 Red 8 Second

Im not to sure how to continue with my attempt:

fid=fopen(fileR);

while ~feof(fid)
  l=fgetl(fid);
  if strfind(l,'Exposures')
   %Found begining of expsoures, continue
   l2=fgetl(fid);    
   if strfind(l2,'Exposure Name="red')
      ....now what??
  end
end

doc xmlread

would probably be better. It is not intuitive code and objects to work with, but once you get used to it it works well to extract exactly what you are looking for.
