XSL filter ignores "omit-xml-declaration" setting in stylesheets

[ghost]

Specifying omit-xml-declaration="yes" in an XSL stylesheet is supposed to suppress the XML declaration (<?xml ...?>) at the top of the generated output. However, nanoc's XSL filter ignores this setting, which causes problems when the filter is used to generate XML fragments for inclusion in other layouts.

The problem is the filter invokes Nokogiri in a way that returns an object representing the transformed XML. When the filter requests a string representation from the object a new XML declaration is naturally generated.

The solution is to change the filter so it fetches the raw output of the transformation, which will make omitted elements stay omitted.

This is another small fix I've made locally and I'll submit a pull request in a moment.

Or rather, I will when GitHub starts cooperating with me.

👍

(Out of curiosity, what are you using the XSL stylesheets for?)

[ghost]

Documentation for a REST API. I'm capturing descriptions of the resources in a simple, custom XML format that is transformed into DocBook reference entries and then into XHTML (and possibly, someday, into XSL-FO and PDF).

@simonsouth If the content is open or sanitized, I would love to see it.
