Question

Background:

I want to take some xml from one file, put it in a template file and then save the modified template as a new file. It works, but when I save the file out, all the nodes that I added have a default namespace prepeneded, i.e.

        <default:ComponentRef Id="C__AD1817F9C64A42F0A14DDDDC82DFC8D9"/>
        <default:ComponentRef Id="C__157DD41D70854617A3D6D1E4A39B589F"/>
        <default:ComponentRef Id="C__2E6D8662F38FE62CAFA9F8842A28F510"/>
        <default:ComponentRef Id="C__54E5E2181323D4A5F37293DAA87B4230"/>

Which I want to be just:

        <ComponentRef Id="C__AD1817F9C64A42F0A14DDDDC82DFC8D9"/>
        <ComponentRef Id="C__157DD41D70854617A3D6D1E4A39B589F"/>
        <ComponentRef Id="C__2E6D8662F38FE62CAFA9F8842A28F510"/>
        <ComponentRef Id="C__54E5E2181323D4A5F37293DAA87B4230"/>

The following is my ruby code:

file = "wixmain/generated/DarkOutput.wxs"
template = "wixmain/generated/MsiComponentTemplate.wxs"
output = "wixmain/generated/MSIComponents.wxs"

dark_output = Nokogiri::XML(File.open(file))
template_file = Nokogiri::XML(File.open(template))

#get stuff from dark output
components = dark_output.at_css("Directory[Id='TARGETDIR']")
component_ref = dark_output.at_css("Feature[Id='DefaultFeature']")

#where to insert in template doc
template_component_insert_point = template_file.at_css("DirectoryRef[Id='InstallDir']")
template_ref_insert_point = template_file.at_css("ComponentGroup[Id='MSIComponentGroup']")

template_component_insert_point.children= components.children()
template_ref_insert_point.children= component_ref.children()

#write out filled template to output file
File.open(output, 'w') { |f| template_file.write_xml_to f }

Update

Example of my template file:

<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'>
  <Fragment>
    <ComponentGroup Id='MSIComponentGroup'>
    </ComponentGroup>
  </Fragment>
  <Fragment Id='MSIComponents'>
      <DirectoryRef Id='InstallDir'>
      </DirectoryRef>
  </Fragment>
</Wix>

Workaround was to remove the xmlns attribute in the input file.

Or to use the remove_namespaces! method when opening the input file

input_file = Nokogiri::XML(File.open(input))
input_file.remove_namespaces!
