【解决方案1】：

首先，您应该查看 Roku SDK 文档，此链接专门用于 Roku 上的 XML 支持：

http://sdkdocs.roku.com/display/sdkdoc/BrightScript+Language+Reference#BrightScriptLanguageReference-45BrightScriptXMLSupport

另外，为了让 Roku 能够解析 XML，XML 内容必须在 <rsp stat="ok"></rsp> 标记内。

您还想查看网格屏幕的文档：

http://sdkdocs.roku.com/display/sdkdoc/roGridScreen

【解决方案2】：

我假设您在 XML 1 中有一个网格屏幕。并且您在 XML 2 中为网格创建了一个组件，现在您希望在 XML 1 中定义的网格屏幕中看到这个 XML 2 组件。

在 XML 1 中，在您定义网格的地方，添加标签

itemComponentName="XML2" '其中 XML2 是您为网格项定义组件的 XML 2 的名称

到网格节点

sub init()
  m.top.functionName = "getcontent"
 end sub

sub getcontent()

  content = createObject("roSGNode", "ContentNode")
  contentxml = createObject("roXMLElement")

  if m.top.contenturi.left(4) = "http"
      readInternet = createObject("roUrlTransfer")
      readInternet.setUrl(m.top.contenturi) 'here give XML path
      contentxml.parse(readInternet.GetToString()) 'parse string from XML his load from browser
  else
       print "Read Asciifile call...."
  end if    

  if contentxml.getName()="Content"

    for each video in contentxml.GetNamedElements("video") 'here element tag is video
      itemcontent = content.createChild("ContentNode")
      itemcontent.setFields(video.getAttributes())
    end for       

  end if

  m.top.content = content

end sub
