Question : extract certain xml nodes from bash script and write them to a file

hello.

for a bash script I am writing, I need to take take the parameters from 1 or more effects in an xml file and write those parameters in separate files (one per effect).

For example, in the xml file attached, I have two effects (one ..... , one ....

I tried something like
EFFECT_1_PARAMETER=`cat my_xml_file | perl -pi -e 's@.*(.*)fectStack>@$1@g' but it does not work and does not enable me to loop through effects in the xml to write each of them to a separate file.

Could anybody help ?
I'm using linux centos 4, and cannot install anything : I would like the script to work straight out of the box.

thanks a lot

Answer : extract certain xml nodes from bash script and write them to a file

This will create an out#.xml, where # starts at 1 for the first pair, and increments for each one.

perl -e 'local $/;$_=<>;s|()|$count++;open(OUT,">out$count");print OUT "$1\n";close($o)|gse;' file.xml
