Traverse catalogs

Here is my problem (it seems I've a lot of problems nowadays).

I have several folders:

runner.20070830.12.45.12
runner.20070830.12.45.15
runner.20070830.12.45.17
runner.20070830.12.45.20
runner.20070830.12.45.45
runner.20070830.12.45.55

Each catalog contains some html-files.

I need to traverse each folder and get some data from a special html-log file in each folder. How can this be done in a simple way?

This may help if you have access to perl:
Perl 5.8 Documentation - File::Find - Traverse a directory tree

But this seems to be for perl? I need something for bash. Also the number of directories will vary so I need the script to search through every folder in speciefied folder.

Problem solved:

cat *folder*/file.html | grep "hola"

*folder* is a name that all the folders have incommon and then I use grep the get the line containing to numbers.

Cheers
