README

Simple scraper for validating nested XML/JSON examples in OpenStack/Rackspace doc files.

General outline

1. Executes a recursive wget for a given URI. The process follows every link nested in a given piece of markup until every possible link is exhausted. It saves each remote URI to the local filesystem. An example location might be: ./docs/docs.openstack.org, where docs.openstack.org is the root URI you specified. Only HTML files are saved, any other remote file type is omitted.

2. Once the wget procedure is complete, the PHP script traverses the local directory recursively, scanning each HTML file for a given regex pattern. The regular expression indicates how code samples are nested into the markup.

3. Once code samples are extracted, the script judges whether it is either JSON or XML. It then executes the relevant parsing test for either type.

4. If the parsing fails, it is likely malformed, and generates an error. These errors can either be output to the console (i.e. STDOUT) or to a local log file.

CLI options

The main script you will need to run is:

./bin/doc-validator

Supported CLI flags

Convenience scripts

To run against docs.openstack.org, run: ./bin/openstack

To run against docs.rackspace.com, run: ./bin/rackspace

Installation

You will need to install this package with Composer:

# Install Composer executable
curl -sS https://getcomposer.org/installer | php

# Install package
php composer.phar require jamiehannaford/doc-validator:1.0.0

You can then access the binary:

./vendor/bin/doc-validator -udocs.foo.com -q -l < /dev/null &

Because you have left the --log-file flag empty, it will log everything to a default location:

./vendor/jamiehannaford/doc-validator/log/docs.foo.com.log
