How to show relationships between Todo-lists?

Question

How can I show relations between ToDo-lists? I am using Devtodo.

I will give an example. I have my MIT humor in one XML-file:

 <todo version="0.1.19">
     <note priority="low" time="1237320287">
         see the MIT humor-video
     </note> 
 </todo>

Other file is about Usenet-humor

 <todo version="0.1.19">
     <note priority="verylow" time="1237321441">
         read about Usenet Humor
     </note> 
 </todo>

When I change one of my humor-file, I would like to have an alert that shows me my other Todo-lists that have a word "humor" in the title.

Partial Solution

I tried to add a property to the cd-command in my .bashrc that keep showing me my main Todo-lists:

alias='ls (); find /* -name mainlist'

but I feel I am doing the job in a hard way. How are you managing your Todo-lists between folders? Have you got a lot of scripts to show relationships between Todo-lists?

Answer 1

I think I would markup some words as keys say with a '<topic>humor</topic> tag then write some thing that would search through the todos to find the related ones . but I'm thinking that the topics would be fewer. So just keep an index by topic of all open todos with those topics in your app, not in the XML.
