Issues installing mashpodder - crontab and xsltproc missing

I’m trying to install on Volumio2 v2.030

I had used this previously on Volumio1 without issue but now have 2 issues

  1. I can’t install crontab (see my reply to a previous question here: crontab-t4986.html)
  2. mashpodder can’t parse the rss and is most likely because it requires xsltproc from: … README.txt:

Can anybody help me install crontab and xsltproc please?

I use mashpodder to configure a number of BBC podcasts to be downloaded regularly so I can listen to later. I’m open to suggestions to another way of downloading podcasts but mashpodder is one simple script which worked pretty well previously.
