+1 for jq. A lot of my work these days involves using web APIs in addition to "local" ones from CLI tools. xpath was good for dealing with XML stuff in a similar fashion, and HTML-XML-utils is an awesome suite of CLI things for slicing and dicing, if you're into that sort of thing: http://www.maketecheasier.com/manipulate-html-and-xml-files-...

xmlstarlet is also handy for command-line XML parsing:

Agree, had to use it extensively several years ago, it saved me so much time. But even then the development seemed to have stopped on this tool.
