PEG-based Parsing for XML-ish Data

Description and Disclaimer

This code provides a single PEG to help parse XML-like strings to produce Janet data structures. It's not an attempt at a complete / correct parser, but it seems to have handled some cases tolerably well.

Usage

Command Line

Zero to sample invocation:

git clone https://github.com/sogaiu/janet-xmlish
cd janet-xmlish
janet -l ./janet-xmlish/grammar -e '(pp (peg/match xmlish-peg "<h1>hi</h1>"))'

Output:

@[{:content @["hi"] :tag "h1"}]

From Code

Assuming installation like:

jpm install https://github.com/sogaiu/janet-xmlish

Code might look like:

(import janet-xmlish/grammar :as xmlish)

(peg/match xmlish/xmlish-peg
           ``<a href="http://127.0.0.1:8000">link</a>``)

Evaluation might yield:

@[{:attrs @{"href" "http://127.0.0.1:8000"}
   :content @["link"]
   :tag "a"}]
