Andra Waagmeester contributed several linux shell scripts to call the web service: download the scripts here. The xmlstarlet tool makes it easy to parse the results. Below is an example on how to parse the results.
./listPathways.sh |\ sed "s/<[A-Za-z0-9]*:/</g"|\ # remove the namespaces sed "s/<\/[A-Za-z0-9]*:/<\//g"|\ # remove the closing namespaces xml sel -t -m //pathways -v "concat(id,',',name,',',species,',',revision,',',url)" -n
