XmlSanitizer

XML sanitization with Loofah and Nokogiri.

scrubber = XmlSanitizer::DefaultPermitScrubber.new
scrubber.tags = ["foo", "bar"]

xml = '<foo><bar><baz>baz</baz></bar></foo>'

XmlSanitizer.sanitize(xml: xml, scrubber: scrubber) # or use your custom scrubber
# => "<?xml version=\"1.0\"?>\n<foo>\n  <bar/>\n</foo>\n"

The default scrubber will remove all non-permitted tags and their subtrees.

Installation

Add this line to your application's Gemfile:

gem 'xml_sanitizer'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install xml_sanitizer

Usage

Sanitize an XML document

scrubber = XmlSanitizer::DefaultPermitScrubber.new
scrubber.tags = ["foo"]
scrubber.direction = :bottom_up # default is :top_down

xml = '<foo><bar><baz>baz</baz></bar></foo>'

XmlSanitizer.sanitize(xml: xml, scrubber: scrubber)
# => "<?xml version=\"1.0\"?>\n<foo/>\n"

with XML namespaces

scrubber = XmlSanitizer::DefaultPermitScrubber.new
scrubber.tags = ["ns:foo"]

xml = '<ns:foo xmlns:ns="http://www.w3.org/TR/html4/"><bar>baz</bar></ns:foo>'

XmlSanitizer.sanitize(xml: xml, scrubber: scrubber)
# => "<?xml version=\"1.0\"?>\n<ns:foo xmlns:ns=\"http://www.w3.org/TR/html4/\"/>\n"

Sanitize an XML fragment

scrubber = XmlSanitizer::DefaultPermitScrubber.new(tags: %w[foo bar])
xml = '<foo><bar>baz</bar></foo>'

XmlSanitizer.sanitize_fragment(xml: xml, scrubber: scrubber)
# => "<foo>\n  <bar>baz</bar>\n</foo>"

Development
