lbstanza-tidy's Introduction

Stanza wrapper for LibTidy

This adds a stanza wrapper around the libtidy implementation. This allows for parsing HTML, XHTML, and XML documents.

Setup

This module includes tidy-html5 as a git submodule for ease of build.

sudo apt install cmake build-essentials
git submodule update --init
cd tidy-html5
mkdir output
cd output
cmake ..
make

This will place the static/dynamic artifacts in the tidy-html5/output directory. The start.sh script references this directory and the tidy-html5/include folder.

If you want to install libtidy using your OS's package manager, you will need to set the environment variables in start.sh to the correct location to find the headers and libraries.

Example

  val doc = TidyDoc()
  val stat = get-status(doc)
  #EXPECT(stat == 0)

  val input = "<!DOCTYPE html><html><head><title>SomeStuff</title></head><body><p id=\"asdf\">SomeText</p><p id=\"qwer\">SomeMoreText</p></body></html>"

  val code = parse-str(doc, input)
  #EXPECT(code == 0)

  val body = get-body(doc)
  val pElems = to-tuple(get-children(body))
  ; pElems = [TidyNode(...), TidyNode(...)]
  ;   Where the pElems are the two 'p' nodes in the body.

See the unit tests for some more examples.
