#read(aip_file = nil) ⇒ Nokogiri::HTML5::Document, String

Read an AIP source file

Depending on whether a local copy of the file exists, either:

  • download from URL to local storage and read from local archive

  • read from local archive

An URL builder method url_for(aip_file) must be defined either in helper.rb or in the AIP parser definition (e.g. ENR-2.1.rb).

Parameters:

  • aip_file (String) (defaults to: nil) —

    e.g. “ENR-2.1” or “AD-2.LFMV” (default: aip)

Returns:

  • (Nokogiri::HTML5::Document, String) —

    HTML as Nokogiri document, PDF or TXT as String

  aip_file ||= aip
  @downloader.read(document: aip_file, url: url_for(aip_file))
end

#select(klass, attributes = {}) ⇒ Array<AIXM::Feature>

Search features previously written to AIXM and return those matching the given class and attribute values

Examples:

select(:airport, id: "LFNT")

Parameters:

  • klass (Class, Symbol) —

    feature class like AIXM::Feature::Airport or AIXM::Feature::NavigationalAid::VOR, shorthand notations as symbols e.g. :airport or :vor as listed in AIXM::CLASSES are recognized as well

  • attributes (Hash) (defaults to: {}) —

    filter by these attributes and their values

Returns:

  • (Array<AIXM::Feature>)
