Re: Aggregation of xml in a directory

[Martin Lüthi]

Hi

Upon recommendation from this list, I initially used XPathDirectoryGenerator,
but it was too slow for online use. Since I know when a file is changed, I
call the following URL which produces one large XML file with the contents of
all files in the directory.

A FileChainingGenerator would probably be a better solution, but here I have a
full Cocoon XML/XSLT solution.  Not very elegant, but at least it works. If
somebody comes up with something better, I'll be happy ;-)

Cheers Martin

Have a look at the XPathDirectoryGenerator in the scratchpad. With it,
you can generate a directory listing, with a node extracted from each
file. Eg, I used it to extract  elements from a list of Ant
scripts:

The relevant config was:

Thanks for the suggestion Steven. What I have done is to write a perl 
script which I run whenever the xml files are updated. This generates an 
XML file which includes all the others in the directory. So in the end I 
don't use DirectoryGenerator or Aggregation in Cocoon - but CInclude works 
fine.

(I better figure out CachingCInclude too.)

Aggregation of xml in a directory

[Alex McLintock]

Hi folks,

I am trying to figure out how to get Cocoon to display all the xml files in 
a directory without being explicitly told each of their names in the sitemap.

I guess I need a combination of the Directory Generator and the Aggregation 
tools.

I am not too worried about the order of the files otherwise I would have to 
use an XML database - which I would like to avoid if possible.

PS I have looked in the Langham/Ziegeler book but can't find anything useful.

Do I need to write a DirectoryAggregation Generator in Java? perhaps others 
would find it useful too.

Alex

Better: combine the DirectoryGenerator with the CInclude Transformer.
