Escape special characters (e.g. &) for XML requests

[rubiii]

this does not work

client = Savon::Client.new "http://example.com"
response = client.get_programs! do |soap|
  soap.namespace = "http://example.com"
  soap.body = { :username => "user", :password => "somePass21&" , :campaignid => 123 }
end

this does

xml = Builder::XmlMarkup.new
xml.username "user"
xml.password "somePass21&"
xml.campaignid 123

client = Savon::Client.new "http://example.com"
response = client.get_programs! do |soap|
  soap.namespace = "http://example.com"
  soap.body = xml.target!
end

the problem here is, that the ampersand inside the password string is not escaped. will get this fixed with the next release.

Is there an option to turn off escaping of special characters? Can we add one if not?

There are wsdls whose elements have processContents="lax". This is typically used when the desired message content is raw xml which is not escaped and in read directly into the system/api.

Is there any chance to turn off that escaping? I have XML in string, which breaks when escaped. I also put other data into the request as a hash, so manually typing all this into soap.xml would not be preferable. If you use first soap.body and then soap.xml the whole body is overwritten.. See below a shortened example.

soap.body = {
  "Example" => {
    "Foo" => "bar",
    "Bar" => "foo"
  },
  "XMLString" => xml_string
}

@vkoivula there's a way to prevent escaping of specific hash values by appending an apostroph to the key.

@rubiii Thanks.

Does this method of escape preventing actually work in Version 2? It seems here https://github.com/savonrb/savon/blob/version2/lib/savon/qualified_message.rb#L22
that any key passed that ends with an exclamation gets the exclamation stripped off before it gets here
https://github.com/savonrb/savon/blob/version2/lib/savon/message.rb#L32

(rdb:1) Gyoku.xml_tag("requestXml!", :key_converter => @key_converter).to_s
"requestXml"

and thus escaping always happens.
