背景:我有一个Wix安装程序,在现有的IIS网站中创建虚拟目录.创建虚拟目录(在安装之前它不存在)但是应该已经创建了IIS网站(用户只需选择要安装到ListBox中的网站).

问题:在卸载时,安装到的IIS网站的物理路径变为空白,该属性没有值.下面是我的主要wix文件的简化版本.我不确定为什么卸载会影响IIS网站,但任何想法都表示赞赏.

注意:我在Wix 3.5和Windows Server 2008 R2,IIS 7上.

所以我已阅读:help scroll-cursor并非常喜欢zz,它将光标所在的行放在窗口中间.

我正在寻找帮助来制作一个类似的映射,zz但是将光标放在窗口高度的20%处(或25%,30%等).

编辑:

感谢ZyX和Drasill,我能够修改他的功能以获得所需的功能:

function ScrollToPercent(percent)
    let movelines=winheight(0)*a:percent/100

    if has("float") && type(movelines)==type(0.0)
        let movelines=float2nr(movelines)
    endif

    let oldso=&so
    execute ":set so=" . movelines
    execute "normal! zt"
    execute ":set so=" . oldso
endfunction

背景:

我想从一个文件中获取一些xml,将其放在模板文件中,然后将修改后的模板保存为新文件.它可以正常工作,但是当我保存文件时,我添加的所有节点都有一个预先定义的默认命名空间,即

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

我想要的只是:

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

以下是我的ruby代码:

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 }

更新

我的模板文件示例:

<?xml version="1.0" …
