Beau-selector NPM

beau-selector

When I say bo, you say 'selector'.

Run XPath or CSS selectors on arbitrary X(HT)ML documents in the command-line.

installation

npm install --global beau-selector

usage

Just pipe a document to bo and provide a selector!

Usage: bo [xpath|css]

If no attribute is given, innerHTML, text or a plain string
will be returned (depending on what is matched)

Options:
  -o, --outer      get outer XML of the element
  -a, --attribute
  -l, --loglevel                                 [default: "silent"]

You can also optionally specify:

--outer to return the full outer markup of selected elements
--attribute <string> an attribute to extract from the selected element (which will only apply if what was selected is an element), e.g. --attribute href
--loglevel <string> to be more shouty, e.g --loglevel verbose
