Re: Usage of XPath

Hello Colin!
Thank you for the reply. I need to learn CVS then.

Yes, it is not a trivial project, but is very interesting. The main 
purpose is to learn Eiffel (and GOBO) and design using eiffelstudio.

The current version is not optimized: 
 
  -- an XML file is open (after browsing the disk)
     * <cases>
         <product> ...
         <product> ...
             ...
         <product> ...

         <customer> ...
         <customer> ...
             ...
         <customer> ...

         <case customer="xxx1" product="yyyy1">
         <case customer="xxx2" product="yyyy2">
             ...
         <case customer="xxxn" product="yyyyn">
       <cases>

  -- it is then parsed
  -- the document of the resulting tree pipe is then copied one
     element at a time into a cache class representing a new XML
     document which contain a copy of the tree-pipe structure
     and lists of pointers to each class beneath the root for 
     browsing convenience.
     * if the structure is corrupt, then it is reestablished wiht
       default elements on the fly.
     *'rescue' is used here to try the exceptions mechanism.
  -- elements can then be removed, modified, added etc in the cache

  -- and just for fun I wanted to use XPATH in this toy program
     the same way it is used in an xsl file.
