regular expressions (parsing strings) [message #36958]

Hi,

My IDL programs need to parse a text file which contains variables that
would need replacing at read-time. Specifically:

#os =unix
#windows_var1 =g:
#windows_var2 =/rootdir/
#unix_var1 =/mnt/groupserver/
#unix_var2 =/rootdir/
#var3 =< <os>_var1 >< <os>_var2 >data/
#var4 =<var3>counterfile.txt

So #var3 eventually becomes '/mnt/groupserver/rootdir/data/' and #var4
becomes 'mnt/groupserver/rootdir/data/counterfile.txt'. And if #os was
set to 'windows', #var4 becomes 'g:/rootdir/data/counterfile.txt'.

I am trying to use regular expressions to replace the text (specifically
using strepex.pro from
http://astro.uni-tuebingen.de/software/idl/aitlib/misc/strep ex.html )
but am having problems with nested tags.

Could anyone point me to somewhere that could help me out ?

Thanks
