It’s been a while since I’ve had to deal with XML, but I remember finding it fairly convenient to restructure XML documents with XSLT. Modifying the data in those documents, much less so. I think there’s a sweet spot.

These are good suggestions, but maybe it’s worth noting that one of the solutions offered in the article is not equivalent: tail -f /some/log/file | grep -E 'thing1.*thing2' This will only match if the subpa
