Nori
Really simple XML parsing ripped from Crack which ripped it from Merb.
Nori was created to bypass the stale development of Crack, improve its XML parser
and fix certain issues.
parser = Nori.new parser.parse("<tag>This is the contents</tag>") # => { 'tag' => 'This is the contents' }
Nori supports pluggable parsers and ships with both REXML and Nokogiri implementations.
It defaults to Nokogiri since v2.0.0, but you can change it to use REXML via:
Nori.new(:parser => :rexml) # or :nokogiri
Make sure Nokogiri is in your LOAD_PATH when parsing XML, because Nori tries to load it
when it's needed.
Typecasting
Besides regular typecasting, Nori features somewhat "advanced" typecasting:
- "true" and "false" String values are converted to
TrueClassand
FalseClass.
- String values matching xs:time, xs:date and xs:dateTime are converted to
Time,
Dateand
DateTimeobjects.
You can disable this feature via:
Nori.new(:advanced_typecasting => false)
Namespaces
Nori can strip the namespaces from your XML tags. This feature might raise
problems and is therefore disabled by default. Enable it via:
Nori.new(:strip_namespaces => true)
XML tags -> Hash keys
Nori lets you specify a custom formula to convert XML tags to Hash keys.
Let me give you an example:
parser = Nori.new(:convert_tags_to => lambda { |tag| tag.snakecase.to_sym }) xml = '<userResponse><accountStatus>active</accountStatus></userResponse>' parser.parse(xml) # => { :user_response => { :account_status => "active" }
Dashes and underscores
Nori will automatically convert dashes in tag names to underscores. For example:
parser = Nori.new parser.parse('<any-tag>foo bar</any-tag>') # => { "any_tag" => "foo bar" }
You can control this behavior with the
:convert_dashes_to_underscores option:
parser = Nori.new(:convert_dashes_to_underscores => false) parser.parse('<any-tag>foo bar</any-tag>') # => { "any-tag" => "foo bar" }
