class Nokogiri::XML::ParseOptions

Parent:
Object

Parse options for passing to Nokogiri.XML or Nokogiri.HTML

Building combinations of parse options

You can build your own combinations of these parse options by using any of the following methods: Note: All examples attempt to set the RECOVER & NOENT options.

Ruby’s bitwise operators

You can use the Ruby bitwise operators to set various combinations.

Nokogiri.XML('<content>Chapter 1</content', nil, nil, Nokogiri::XML::ParseOptions.new((1 << 0) | (1 << 1)))
Method chaining

Every option has an equivalent method in lowercase. You can chain these methods together to set various combinations.

Nokogiri.XML('<content>Chapter 1</content', nil, nil, Nokogiri::XML::ParseOptions.new.recover.noent)
Using Ruby Blocks

You can also setup parse combinations in the block passed to Nokogiri.XML or Nokogiri.HTML

Nokogiri.XML('<content>Chapter 1</content') {|config| config.recover.noent}

Removing particular parse options

You can also remove options from an instance of ParseOptions dynamically. Every option has an equivalent no{option} method in lowercase. You can call these methods on an instance of ParseOptions to remove the option. Note that this is not available for STRICT.

# Setting the RECOVER & NOENT options...
options = Nokogiri::XML::ParseOptions.new.recover.noent
# later...
options.norecover # Removes the Nokogiri::XML::ParseOptions::RECOVER option
options.nonoent # Removes the Nokogiri::XML::ParseOptions::NOENT option
