parse_namespaces fails with undefined method `gsub' for 0:Fixnum

[PiotrNestor]

ruby 1.9.3 wasabi 2.1.0

I'm getting the following problem when parsing SOAP:

NoMethodError: undefined method gsub' for 0:Fixnum
/usr/lib/ruby/gems/1.9.1/gems/wasabi-2.1.0/lib/wasabi/parser.rb:58:inblock in parse_namespaces'
55: @namespace = namespace.to_s if namespace
56:
57: @namespaces = @document.collect_namespaces.
=> 58: inject({}) { |result, (key, value)| result.merge(key.gsub(/xmlns:/, "") => value) }
59: end
60:
61: def parse_endpoint
/usr/lib/ruby/gems/1.9.1/gems/wasabi-2.1.0/lib/wasabi/parser.rb:57:in `each'

The problem is that 'collect_namespaces' returns a hash like:

{ 0 => ["xmlns:wsdl", "http://schemas.xmlsoap.org/wsdl/"] }

The 'inject' should be then like:

inject({}) { |result, (key, value)| result.merge(value[0].gsub(/xmlns:/, "") => value[1]) }

Is this a known problem with wasabi parse_namespaces? Is the fix acceptable?

Regards Piotr

just tested the collect_namespaces method and for me it's returning the expected result:

{ "soap" => "http://schemas.xmlsoap.org/wsdl/soap/",
  "tns"  => "http://v1_0.ws.auth.order.example.com/",
  "wsdl" => "http://schemas.xmlsoap.org/wsdl/" }

can you provide me with that wsdl, your ruby version and the version of nokogiri you're running?

installed ruby 1.9.2-p0 and tested with both wasabi (2.1.0):

require "wasabi"
doc = Wasabi.document File.read("vapix.wsdl")
doc.parser.namespaces

# { "wsdl" => "http://schemas.xmlsoap.org/wsdl/", ...
#    "wstop" => "http://docs.oasis-open.org/wsn/t-1" }

and nokogiri (1.5.2):

require "nokogiri"
doc = Nokogiri.XML File.read("vapix.wsdl")
doc.collect_namespaces

# { "xmlns:wsdl" => "http://schemas.xmlsoap.org/wsdl/", ...
#   "xmlns:wstop" => "http://docs.oasis-open.org/wsn/t-1" }

can you run the code snippets above and verify that nokogiri's collect_namespaces method is the problem?

[PiotrNestor]

I get the following results with wasabi 2.1.0

require "wasabi"
doc = Wasabi.document File.read("vapix.wsdl")
doc.parser.namespaces

{"h"=>"t"}

and with nokogiri 1.5.2

require "nokogiri"
doc = Nokogiri.XML File.read("vapix.wsdl")
doc.collect_namespaces

{"xmlns:wsdl"=>"http://schemas.xmlsoap.org/wsdl/",
 "xmlns:aa"=>"http://www.axis.com/vapix/ws/action1",
 "xmlns:wsnt"=>"http://docs.oasis-open.org/wsn/b-2",
 "xmlns:soap"=>"http://schemas.xmlsoap.org/wsdl/soap12/",
 "xmlns"=>"http://www.w3.org/1999/xhtml",
 "xmlns:xs"=>"http://www.w3.org/2001/XMLSchema",
 "xmlns:wstop"=>"http://docs.oasis-open.org/wsn/t-1"}

[rubiii]

don't know why it would return { "h" => "t" }, but it looks like collect_namespaces isn't the problem, right? at least it returns the namespaces as expected instead of returning:

{ 0 => ["xmlns:wsdl", "http://schemas.xmlsoap.org/wsdl/"] }

[koppen]

For what it's worth, with Nokogiri 1.5.2 I am in line with @rubiii in getting a result from collect_namespaces like:

{"xmlns:wsdl"=>"http://schemas.xmlsoap.org/wsdl/", "xmlns:aa"=>"http://www.axis.com/vapix/ws/action1", "xmlns:wsnt"=>"http://docs.oasis-open.org/wsn/b-2", "xmlns:soap"=>"http://schemas.xmlsoap.org/wsdl/soap12/", "xmlns"=>"http://www.w3.org/1999/xhtml", "xmlns:xs"=>"http://www.w3.org/2001/XMLSchema", "xmlns:wstop"=>"http://docs.oasis-open.org/wsn/t-1"}

... which is also the format the Nokogiri documentation details at http://nokogiri.org/Nokogiri/XML/Document.html#method-i-collect_namespaces.

@PiotrNestor , are you sure you're using pristine, unmodified versions of Nokogiri and Wasabi to get your results? The {"h"=>"t"} result looks a lot like what you'd get running your suggested inject on the documented response from collect_namespaces:

# Ruby 1.9.2, Nokogiri 1.5.2:
require 'nokogiri'
doc = Nokogiri.XML File.read("vapix.wsdl")
doc.collect_namespaces
# => {"xmlns:wsdl"=>"http://schemas.xmlsoap.org/wsdl/", "xmlns:aa"=>"http://www.axis.com/vapix/ws/action1", "xmlns:wsnt"=>"http://docs.oasis-open.org/wsn/b-2", "xmlns:soap"=>"http://schemas.xmlsoap.org/wsdl/soap12/", "xmlns"=>"http://www.w3.org/1999/xhtml", "xmlns:xs"=>"http://www.w3.org/2001/XMLSchema", "xmlns:wstop"=>"http://docs.oasis-open.org/wsn/t-1"}
_.inject({}) { |result, (key, value)| result.merge(value[0].gsub(/xmlns:/, "") => value[1]) }
# => {"h"=>"t"}

closing this as the problem doesn't seem to be related to wasabi.
